Operating Instructions

Daikin RoCon+ HP

Daikin controller RoCon+ HP1

008.1447899_00 – 09/2019 – EN

2 Product description

INFORMATION

The RoCon+ HP controller is part of the Daikin Altherma

ETS(X/H).

It consists of theswitching panel PCB RoCon BM2Cto

which the actuators and sensors as well as other compon-

ents in the regulating system are connected and the oper-

ating unit RoCon+ B1.

These operating instructions only explain the functions and

possible settings of the controller. More detailed informa-

tion on other device components can be found in the other

applicable documents.

The electronic, digital controller is able to automatically control all

heating and hot water functions for a direct heating circuit, a storage

loading circuit and also further heating circuits via optionally connect-

ible mixer modules, depending on the heating device.

It undertakes all safety management for the Daikin Altherma ETS(X/

H). In the event of a water shortage or undefined operating states,

this executes a safety switch-off. A corresponding error message

shows the operator all the information regarding fault causes.

All function settings for the Daikin Altherma ETS(X/H) and the op-

tional RoCon devices that are connected via the data bus are under-

taken with the control elements of the integrated RoConB1 control

panel and shown on the plain text display with coloured backlighting.

The following additional, optional devices can be connected to the

Daikin Altherma ETS(X/H) via the controller data bus:

▪ Room controller EHS157034

▪ EHS157068 mixer module

In addition, the RoCon+ HP controller has a frost protection function

for the direct heating circuit and the storage tank charging circuit as

well as an automatic function for heating support (integration of an

additional heat source such as a wood-burning boiler or solar sys-

tem).

The potential-free AUX switching contact can be used to carry out

different control functions in conjunction with external devices (re-

quest from an external heat generator, switching to bivalent operat-

ing mode, external status display, etc.).

In addition, it also has several inputs for assessing external control

contacts (external operating mode switching or heat request, Smart

Grid and low rate EVU functions(1)).

The optional outside temperature sensor installed on the north side

of the building can be used to further optimise the weather-com-

pensated feed temperature controller.

If the optional EHS157056 gateway is installed and connected to the

Internet, the Daikin Altherma ETS(X/H) can be conveniently mon-

itored and operated by remote control using a mobile phone (app).

Initial commissioning of the heating system is described in the in-

stallation instructions for the Daikin Altherma ETS(X/H).

Certain menu items of the RoCon+ HP controller are only accessible

to the heating expert. This security measure ensures that no un-

desirable malfunctions arise during operation of the system through

incorrect settings.

All settings for the allocated heating circuit can be carried out in the

same way as the operating unit. If the terminal function is activated,

all operating possibilities that are available on the integrated operat-

ing unit are available with the exception of certain special functions

(e.g. manual operation).

After appropriate assignment, a connected EHS157068 mixer mod-

ule is also operated using the RoCon+ B1 control panel and/or the

EHS157034 room station.

2.1 Temporary shutdown

CAUTION

A heating system that is shut down can freeze in the event

of frost and may suffer damage.

▪ Drain the heating system that is shut down if there is

danger of frost.

▪ If the heating system is not drained, the power supply

must be ensured and the external main switch must re-

main switched on if there is a danger of frost.

If the indoor unit is not required for a lengthy period, it can be tem-

porarily decommissioned.

However, we recommend not to disconnect the system from the

power supply but merely to switch it to "Standby mode" (see Control-

ler operating instructions).

The system is then protected from frost. The pumps and valve pro-

tection functions are active.

If it is not possible to guarantee the power supply when there is

danger of frost,

▪ completely drain the indoor unit on the water side, or

▪ apply suitable antifreeze measures to the connected heating sys-

tem and hot water storage tank (e.g. draining).

INFORMATION

If there is a danger of frost for only a few days with uncer-

tainly in the gas and power supply, the oes not need to be

drained because the heat insulation is very good as long

as the storage tank temperature is observed regularly and

does not fall below + 3°C.

However, this provides no frost protection for the connec-

ted heat distribution system.

(1) The energy supply company (EVU) sends signals that are used for controlling the power mains loading and that have an influence on the cost

of the power and availability.

3 Operation

3.1 General

DANGER: RISK OF ELECTROCUTION

If electrical components come into contact with water, this

can cause an electric shock as well as cause potentially

fatal burns or injuries.

▪ The displays and keys of the control unit must be pro-

tected against the effects of moisture.

▪ To clean the control unit, use a dry cotton cloth. The

use of aggressive cleaning agents and other fluids can

cause damage to devices or lead to an electric shock.

INFORMATION

The Daikin Altherma ETS(X/H) makes the most effective

use of energy at the lowest possible return and hot water

target temperatures.

If an external heat generator (e.g. the optional backup

heater) is activated at feed target temperatures above

50°C, the efficiency (COP) of the Daikin Altherma ETS(X/

H) can deteriorate (depending on the outside temperature).

008.1447899_00 – 09/2019 – EN

4 Function

The system fully automatically controls the operation of the room

heating, room cooling and domestic hot water preparation on the

sanitary side on the basis of the specifications set in the RoCon+ HP

controller. The functions that can influence system operation are de-

scribed below.

Some of the functions and parameters described are restricted by

access rights and can only be set by a heating specialist (see

Chap. 4.5.1).

4.1 Mode

[→Main menu →Operating mode]

This menu is used to select the operating mode for operating the

device. The current operating mode is indicated by a corresponding

symbol on the start screen.

Standby operating mode (Standby)

NOTICE

A heating system that is not protected against frost can

freeze in the event of frost and thus be damaged.

▪ Drain the heating system on the water side if there is a

danger of frost.

▪ If the heating system is not drained, the power supply

must be ensured and the mains switch must remain

switched on if there is a risk of frost.

In this operating mode, the Daikin Altherma ETS(X/H) is switched to

standby mode. The frost protection function remains unchanged. In

order to maintain this function, the system must not be disconnected

from the mains.

All controllers integrated in the RoCon system via the CAN bus are

primarily also switched to the "Standby" operating mode.

INFORMATION

In the [Standby] operating mode, the heat pump and the

optionally connected backup heater are disconnected from

the power supply (energy-saving mode) if the following

conditions are met:

▪ the outside temperature sensor is connected and cor-

rectly parametrised in the system configuration

▪ the outside temperature is more than 8°C

▪ there is no heating request

▪ the frost protection function is not active in any connec-

ted HC and

▪ the Daikin Altherma ETS(X/H) has been switched on

for at least 5minutes.

Reduce operating mode

Reduced heating operation (lower room target temperature) accord-

ing to the set reduction temperature in the [Reduce room temperat-

ure] parameter (see Chap. 4.2).

Domestic hot water preparation according to the feed target temper-

atures and switching cycles in the [Hot water auto. 1] hot water time

program (see Chap. 4.2).

Heating operating mode

Heating, cooling mode according to the room target temperature set

in the [Room temperature target 1] parameter (see Chap. 4.2).

A connected outside temperature sensor (weather-compensated

feed temperature control) or a connected room controller also influ-

ence the target temperature.

Domestic hot water preparation according to the feed target temper-

atures and switching cycles in the [Hot water auto. 1] hot water time

program (see Chap. 4.2).

Summer operating mode

Only domestic hot water preparation according to the set target tem-

peratures and switching cycles is carried out in the [Hot water auto.

1] hot water time program (see Chap. 4.2).

All controllers integrated in the RoCon system via the CAN bus are

also switched to the higher-level [Summer] operating mode.

Automatic 1 operating mode (time program)

Automatic heating and setback mode according to the permanent

time programs (see Chap. 4.3):

▪ [Heating circuit auto. 1]

▪ [Hot water auto. 1]

INFORMATION: SWITCHING CONTACT FOR EX-

TERNAL OPERATING MODE CHANGEOVER

Switching can also be performed from an external device

(e.g. modem, ...) via a floating switching contact connected

to terminal J8 of the Daikin Altherma ETS(X/H) to the "Ext"

terminals. See Tab. 4-1.

In this case, the switching contact functionality is depend-

ent on the parameter [Func. burner blocking contact]:

▪ [Func. burner blocking contact] = Resistance values

(default setting): Evaluation of the resistance values.

▪ [Func. burner blocking contact] = Burner blocking con-

tact: Evaluation as a burner blocking contact. If the

switching contact is closed, the external heat generator

has priority.

Tab.4-1 Resistance values for evaluating the EXT signal

INFORMATION

The resistances specified in Tab. 4-1 in a tolerance field of

5%. Resistances outside this tolerance field are interpreted

as an open input. The heat generator switches back to the

previously active operating mode.

The input is not considered for resistance values greater

than the value for "Automatic 2".

If several switching contacts are connected to the Daikin

Altherma ETS(X/H) (e.g. smart grid, room thermostat), the

associated functions may have a higher priority than the

external mode switching. The operating mode requested

by the EXT switching contact is then possibly not activated

or is only activated later.

Besides these operating modes, different temporary time programs

(see Tab. 4-2) are available that are carried out with priority after ac-

tivation.

surised storage tank water in the Daikin Altherma ETS(X/H) hot wa-

ter storage tank.

▪ On use of the optional EKBUxx backup heater, this is carried out

due to the design installation situation.

▪ If an alternative WEZ (e.g. gas- or oil-fired boiler) is used, this can

be hydraulically integrated

▪ unpressurised via the connections (solar feed and solar return)

of the hot water storage tank or

▪ in the case of Daikin Altherma ETS(X/H) ...B device types, via

the integrated pressurised solar system heat exchanger

The setting of the [Config. ext. heat source] parameter is used to

define if any additional heat generator (WEZ) is available for do-

mestic hot water preparation and heating support, and which.

▪ No external heat source

▪ Optional backup heater

▪ Ext. heat sources HW and HZU: Alternative WEZ provide do-

mestic hot water preparation and backup heating. To request the

WEZ, relay K3 on PCB RTX-EHS is switched.

▪ Ext. heat source HW or HZU: Alternative WEZ 1 (optional backup

heater EKBUxx) undertakes domestic hot water preparation and

alternative WEZ2 undertakes heating support. To request WEZ 1,

relay K3, and to request WEZ 2, relay K1, on PCB RTX-EHS are

switched respectively. Heed warning notice! The operation of an

Smart grid

WARNING

There is a danger of scalds at hot water target temperat-

ures over 65°C. This is possible because the utility com-

pany (EVU) is entitled to control current draw optimised ac-

cording to supply and demand in the definitions for Smart

Grid.

Due to such forced charging, the hot water target temper-

ature in the hot water storage tank can exceed 65°C.

This storage tank charging is carried out even when the

[Standby] operating mode is set.

▪ Install scald protection in the hot water distribution line.

To use this function, a special electricity meter with SG receiver to

which the Daikin Altherma ETS(X/H) must be connected is required.

As soon as the function is activated by the [Smart grid] parameter,

the heat pump is set to an operating mode as per Tab. 4-4 depend-

ing on the utility company signal.

Interlink function

Setting the [Interlink function] parameter = On offers the possibility

that the Daikin Altherma ETS(X/H) two different feed temperature

setpoints are included in the controller.

This applies to both weather-compensated control and control ac-

cording to a fixed feed target temperature (see Chap. 4.5).

One possible application is, for example, the additional integration of

an HP convector in a surface heating and cooling system.

Prerequisite: 2 switching contacts are connected to Daikin Altherma

ETS(X/H) plug connection J16 (e.g. room thermostats).

▪ [Interlink function] parameter = Off: Deactivated

▪ [Interlink function] parameter = On: Evaluation of the heating and

cooling switching contacts at plug connection J16 on the RoCon

4.4.5 Intelligent storage tank management

[→Main menu →Settings →ISM]

If the storage temperatures are high enough, the energy in the stor-

age tank can be used for room heating. This can either increase

comfort ([Continuous heating] function) or make it possible to use

energy from an external heat source, e.g. solar, when heating is re-

quired ([Heating support (HZU)] function).

Continuous heating

This function enables uninterrupted heating, even when the evapor-

ator is being defrosted. This enables high comfort to be guaranteed,

even with rapidly reacting heating systems (e.g. convectors).

Heating support (HZU)

If the Heating support function ([Heating support (HZU)] parameter =

On) is activated, the energy in the Daikin Altherma ETS(X/H)'s integ-

rated storage tank is used to undertake the heating function. If the

storage temperature is sufficiently high, the burner remains inactive.

The minimum value (THZUmin) is calculated as follows: THZUmin = cur-

rently active hot water target temperature [Hot water temperature,

target] + [Heating support hysteresis] parameter.

Switch-on condition:

Tdhw > THZUmin + 4K and Tdhw > [Hot water temperature, target] in-

formation parameter + 1K

If the switch-on condition is fulfilled, heat is taken from the storage

tank and this is used to supply the heating system.

Switch-off condition:

Tdhw < THZUmin or Tdhw < [Feed temperature, target] parameter (see

Chap. 4.5.3)

If the switch-off condition is fulfilled, the heating support from the hot

water storage tank is set and the burner takes over the heating oper-

ation.

The [Heating support power] parameter limits the maximum power

that can be taken. The [Heating support max. temp.] parameter limits

the maximum temperature that can enter the heating system.

Further explanations and possible settings for the parameters in this

menu can be found in Chap. 7.5.5.

sure setpoints for the water side can be defined.

Further explanations and possible settings for the parameters in this

menu can be found in Chap. 7.6.1.

4.5.3 HC configuration

[→Main menu →Configuration →HC config]

This menu is used to adjust the basic functionality of the heating cir-

cuit.

Further explanations and possible settings for the parameters in this

menu can be found in Chap. 7.6.2.

Weather-dependent feed temperature control

If the weather-compensated feed temperature control is active, the

feed temperature ([Feed temperature, target] parameter) is determ-

ined automatically according to the set heating/cooling curve de-

pending on the outside temperature.

This function is activated in the delivery condition. It can only be de-

activated (fixed value control) or reactivated with a technician code.

If the room controller is also connected (EHS157034) to the RoCon+

HP, the target temperatures are controlled according to the weather

and room temperature ([Room influence] parameter).

This function can only be configured using the technician code. Con-

tact your heating expert in this regard.

This function is activated or deactivated via the [Weather-com-

pensated] parameter in the "Configuration" menu.

▪ [Weather-compensated] parameter = Weather-compensated:

Weather-compensated feed temperature control

▪ [Weather-compensated] parameter = Feed temperature, fixed:

Control based on fixed target temperature

▪ For heating mode: [Feed temperature, heating mode] para-

meter or [Feed temperature, reducing mode] parameter

▪ For cooling mode: [Feed temperature, cooling mode] parameter

INFORMATION

The weather-compensated feed temperature control has

no influence on the feed target temperature in the case of

a hot water circuit request.

With connected Mixer module

The setting of the heating/cooling curves and the activation of the

weather-compensated feed temperature control for the assigned HC

are carried out in the same way as described above.

The assigned HC can be operated as a:

▪ Mixer add-on

The outside temperature of the outside temperature sensor con-

nected to the Daikin Altherma ETS(X/H) external temperature

sensor is transmitted to the mixer module via the CAN bus.

or as a

▪ Mixer add-on with zone control

A separate outside temperature sensor must be connected to the

mixer module. The assigned HC is controlled according to the out-

side temperature relevant for this zone.

If the terminal function is activated, the mixer module can be oper-

ated and the settings for the assigned heating circuit undertaken via

the RoCon+ B1 control panel of the Daikin Altherma ETS(X/H).

In conjunction with the EHS157034 room control, the mixer module

can also control the assigned heating circuit completely autonom-

ously and independently of the heat generator.

Further explanations and possible settings for this menu can be

found in Chap. 7.6.

Frost protection function

The integrated heating circulation pump is switched on at an external

temperature below the [Frost protection temperature] parameter

value in order to prevent the heating system from freezing.

In addition, the feed, storage and connected room temperature

sensors are also constantly monitored. If the temperature measured

by one of these sensors falls below 7°C (below 5°C at room tem-

perature), the antifreeze function is also activated.

If the heating feed temperature falls below 7°C, the Daikin Altherma

ETS(X/H) heats until the heating feed temperature reaches at least

12°C.

The function is ended if the external temperature rises above the set

[Frost protection temperature] parameter value + 1K and also there

is no other activation condition.

INFORMATION

If low rate functions are activated,

[HT/NT function] parameter = Switch all off

[Smart grid] parameter = On

operation of the heat pump can be shut off completely for a

limited period of time by the utility company. In these

cases, regulation is not possible even in frost protection

conditions and the device's internal heating circulation

pump is not switched on.

These situations can be recognised if, in the [→Main

menu →Information →Overview] menu in the operating

data field: "Ext", the "High rate" value or "SG1" is dis-

played.

Heating curve

WARNING: FLAMMABLE MATERIAL

In the event of malfunction, the floor heating system, the

screed or the floor structure could be damaged due to

overheating.

▪ Prior to initial commissioning, set the maximum temper-

ature limit in the RoCon+ HP controller ([Max. feed

temperature] parameter) to the maximum permitted

system temperature prior to starting the emission

measurement.

▪ Connect an overheating protection switch (in the build-

ing) at the "Ext" plug connection for external operating

mode switch-over so that the Daikin Altherma ETS(X/

H) is switched to the "Standby" or "Summer" operating

mode. If the [Room thermostat] parameter = Yesor the

[Interlink function] parameter = On, the overheating

protection switch must be connected so that the room

thermostat's switching contact is interrupted.

▪ If the floor heating is also used for room cooling, the

connection notes in the above point also apply to the

connection of a moisture protection switch in the build-

ing.

The heating curve is used to adapt the feed temperature to the char-

acteristics of the building independent of the respective outside tem-

perature (weather-compensated feed temperature control, see

Chap. 4.5). Generally speaking, the slope of the heating curve de-

scribes the ratio of the feed temperature change to the external tem-

perature change.

The heating curve is valid within the limits of the minimum and max-

imum temperatures set for the respective HC. The room temperature

measured in the occupied area may differ from the required room

temperature; these deviations can be kept to a minimum by installing

a room thermostat or a room control.

The controller is set at the factory in such a way that the heating

curve does not independently adjust itself during operation.

The automatic heating curve adjustment can be activated ([Heat-

ing curve adaptation] parameter) if the outside temperature sensor

and the room controller (EHS157034) are connected (see

Chap. 4.5).

Start conditions for automatic heating curve adjustment:

▪ Outside temperature <8°C

▪ Operating mode is [Automatic 1] or [Automatic 2]

▪ Duration of the setback period is at least 6h

If no automatic heating curve adjustment is activated, the heating

curve can be manually adjusted by adjusting the [Heating curve]

parameter).

INFORMATION: MANUALLY ADJUSTING THE HEAT-

ING CURVE

Do not make any corrections to the set values for 1 – 2

days, and then only make them in small increments.

▪ Deactivate the external heat sources (e.g. stoves, dir-

ect sunlight, open windows).

▪ Fully open any radiator thermostat valves or actuators.

▪ Activate "Heating" operating mode. Approximate setting

values:

Heating element: 1.4 to 1.6.

Floor heating: 0.5 to 0.9.

Comfort heating

If the heat pump cannot cover the heating demand when outside

temperatures are very low, heat is extracted from the storage tank

and used for room heating. In rare cases (in systems with high re-

quired feed temperatures and low required hot water temperatures),

the required feed temperature can be higher than the storage tank

target temperature. In order to avoid short-term loss of comfort in

heating mode for these systems, the [Comfort heating] parameter

can be set to "On". At corresponding outside temperatures, the stor-

age tank temperature is raised above the storage tank temperature

set for the hot water requirement.

INFORMATION

If [Comfort heating] is set to "On", the power consumption

of the heat pump may increase. In the default setting,

[Comfort heating] is set to "Off".

Detailed explanations and possible setting values of this function can

be found in Chap. 7.6.

4.5.5 Cooling

[→Main menu →Configuration →Cooling]

This menu is used to make settings for cooling mode.

CAUTION: DANGER OF CONDENSATION

In the event of malfunction or incorrect parameter settings,

the floor heating, the screed or the floor structure could be

damaged due to condensation.

▪ Prior to initial commissioning and activation of cooling

mode, set the minimum temperature limit to the min-

imum permissible system temperature in the RoCon

controller (parameter [Feed temperature lower limit]).

Prerequisites for cooling mode:

▪ Outside temperature > set value of room target temperature

▪ Outside temperature > set value of the [Start cooling outside

temp.] parameter

▪ [Cooling] operating mode activated.

▪ via menu "Operating mode" or

▪ via room thermostat function (cooling switching contact closed)

▪ No heat request active in the heating system's RoCon system.

INFORMATION

If the mean outside temperature falls below 4°C when

"Cooling" operating mode is active, the operating mode

automatically switches to "Heating".

Renewed automatic operating mode switching to "Cooling"

only takes place:

▪ if a room thermostat is connected to plug connection

J16 (cooling) and

▪ the room thermostat's switching contact is closed and

▪ the mean outside temperature increases to over 10°C

again.

Cooling curve

[→Main menu →Configuration →Cooling →Cooling curve]

The cooling curve determines the feed target temperature in cooling

mode depending on the respective outside temperature. (for

weather-compensated feed temperature control, see Chap. 4.5.3).

Warmer outside temperatures result in a colder feed target temperat-

ure and vice versa. The cooling curve can be adapted to the condi-

tion of the building by four parameters (see Fig. 4-3).

1 [Start cooling outside temp.]

2 [Max. cooling outside temp.]

3 [Target flow cooling, start]

4 [Target flow cooling, max.]

Cooling parameters

[→Main menu →Configuration →Cooling →Parameters]

This menu combines further parameters to determine target feed

temperatures in cooling mode.

During weather-dependent T-HS control, the user can increase or

decrease the target feed temperature by a maximum of 5K with the

parameter [Cooling setpoint correction]. A temperature reduction is

limited by the [Feed temperature lower limit] parameter.

INFORMATION

If optional frost protection valves are installed in the sys-

tem, the [Feed temperature lower limit] parameter must not

be set below 7°C.

4.5.6 Domestic hot water

[→Main menu →Configuration →DHW]

The domestic hot water preparation can be individually adapted to

the behaviour and requirements of the users in this menu. This min-

imises energy consumption and increases comfort.

Solar function

The [Solar function] is used to reduce the target temperature of the

hot water storage tank in order to increase the yield of a connected

solar system. The target value of the hot water temperature is set as

a function of the outside temperature and in compliance with the

safety functions. In addition, the following parameters are defined:

Hot water hysteresis= 5K; Building insulation= Normal

To activate the solar function, it must be set to "On" in the menu

[→Main menu →Configuration →DHW →Solar function] and the

switching contact EXT (J8) must be closed.

Settings for optional circulation pump

Depending on the [Circulation pump control] parameter, an optional

circulation pump can be controlled synchronously with the selected

time program for domestic hot water preparation or with the time pro-

gram for the circulation pump (see Chap. 4.3). During the release

times of the selected time program, the circulation pump can be op-

erated either continuously or cycled. This is defined with the [Circula-

tion pump interval] parameter.

Anti-legionella protection

This function is used to prevent bacterial contamination in the hot

water tank by thermal disinfection. To do so, the hot water tank is

heated 1× daily or 1× weekly to the disinfection temperature [Anti-le-

gionella temperature] depending on the [Anti-legionella day] para-

meter. Disinfection starts at the specified start time [Anti-legionella

start time] and is active for one hour. An optionally connected circu-

lation pump is automatically switched on during this time.

Detailed explanations and possible setting values of this function can

be found in Chap. 7.6.5.

4.5.7 Additional program

[→Main menu →Configuration →Addition]

This menu combines programs which simplify initial commissioning

of the system.

Air purge function

[→Main menu →Configuration →Addition →Ventilation]

By activating the ventilation function, the controller starts a fixed

defined sequence program with start/stop operation of the integrated

heating circulation pump and various positions of the integrated 3-

way switching valves. Existing air can escape during operation via

the automatic ventilation valve.

INFORMATION

The activation of this function does not replace correct

venting of the HC.

The HC must be completely full before activating this func-

tion.

Relay Test

[→Main menu →Configuration →Addition →Relay test]

This program allows testing of internal switching relays. This may be

necessary in the event of malfunctions, error messages or as part of

annual maintenance. When the menu is opened, all relays are deac-

tivated. Selecting one or more relays activates them. When the

menu is exited, all relay tests are terminated.

The relay test menu is operated in the same way as list entries (see

Chap. 3.3.3). However, several relays can be activated in parallel in

the relay list for testing. To do this, select the corresponding relay

with "OK". Activated relays are indicated by a tick.

Floor screed dryout

[→Main menu →Configuration →Addition →Screed]

The screed drying is started in the menu according to the settings in

[Screed program]. The program is used exclusively for the pre-

scribed drying of newly created screed for floor heating systems.

The first day of the screed program begins after activation of the pro-

gram at the change of day at 00:00.

Screed drying is a special function and is not interrupted by any

other operating mode. It can only be activated by the heating expert

for the direct HC and/or optionally connected mixed HCs. It must be

activated separately for each HC.

INFORMATION

Before starting the screed drying, the [Room thermostat]

and [Interlink function] parameters must be deactivated.

During a short-term power failure, a previously activated

screed drying is continued at the point of the interruption.

After activation of the screed drying, all weather-compensated con-

trol functions of the respective HC are switched off. The respective

HC works as a constant temperature control regardless of the oper-

ating mode and switching times.

Already activated screed drying can be deactivated at any time. After

ending the screed drying, the parameter is automatically set to "Off"

and the HC works according to the currently set operating mode

again.

Floor screed program

[→Main menu →Configuration →Addition →Program]

This menu allows the individual adjustment of the factory settings for

the duration and feed target temperatures of the screed drying.

Changes can only be made after entering the specialist code.

Changing the screed program

A separate feed target temperature can be set for each day for a

maximum duration of 28 days. The end of the screed program is

defined by the first day without a preset feed target temperature.

Typical screed programs

Function heating

The function heating serves as proof of the production of defect free

work for the heating engineer. A prefabricated heating protocol relat-

ing to floor heating systems can be found on the manufacturer's In-

ternet portal.

In this sense, the function heating (identical with "Heating" in

EN1264, section 5.2) is not considered as a heating process to

achieve workability of the screed. Generally, a special screed curing

heating and/or mechanical drying is required for this.

The heating of cement screeds should be carried out after 21days

at the earliest and of anhydrite screeds after 7 days at the earliest in

accordance with the specifications of the manufacturer. The first

heating begins with a feed temperature of 25°C that must be main-

tained for 3days. Afterwards, the heating is carried out with the max-

imum set feed temperature for the HC (limited to max. 55°C), which

must be maintained for a further 4days.

After the described heating process, it is not yet assured that the

screed has reached the required moisture content for workability of

the screed.

The moisture content in the screed must be checked by measure-

ment prior to laying the surface covering.
