7Controller description

Controller structure

The controller (1) has a single module

construction, which includes a control panel

and an main module. To operate the system,

an external temperature sensor (3) connected

to the controller module via a cable (2) is

necessary. The controller should be placed in

the boiler room close to electrical devices

included in the central heating system.

Controller operation

Heat source

The controller controls the operation of heat

source, equipped with an ON-OFF contact,

e.g. an automatic gas, oil or pellet boiler, by

activating or deactivating it according to a

heat demand of the central heating system. It

has a 0-10V control output, which is used to

modulate the heat source's power depending

on the heating system's heat demand.

Hot domestic water

The controller controls the operation of DHW

pump loading a hot water tank up to a user-

defined temperature. Preparation of DHW can

be programmed in time intervals. The

controller also controls a DHW circulating

pump. It enables quick transportation of DHW

to a bathroom or kitchen located far away.

Heating circuits

The controller control the operation of one

direct heating circuit and two adjustable

heating circuits. Water temperature in heating

circuits is set by weather, i.e. water

temperature in the heating circuit is calculated

in accordance with a temperature from the

external sensor. Due to this, despite of

varying external temperature, a room

temperature in heated compartments are kept

on a set level.

Dependent heating circuits

The temperature in individual heating circuits

can be asked in several ways:

- weather control –with consideration to

external temperature sensor readings,

- constant value –without external

temperature sensor,

- with using modes of work with time

schedules, without using additional room

thermostats,

- with using room thermostats or other

heating systems, which by means of contacts

(closed) affect individual heating circuits.

Solar system

The controller controls a basic solar system

heating the DHW tank. Apart from

temperature sensors, no additional module is

necessary to operate the solar system.

INSTALLATION AND SERVICE SETTINGS

Multi-Mix

9Controller assembly

Environmental conditions

Due to fire risk it is forbidden to use the

controller in proximity of explosive gases or

dust. Moreover the controller cannot be used

in conditions of water steam condensation or

be exposed to effects of water.

Storage and transport

conditions

The controller cannot be exposed to

immediate effects of atmospheric conditions

i.e. rain or sunrays. Temperature of storage

and transport should be within scope

-15…+65°C.

Mounting requirements

Regulator should be installed by qualified and

authorized technician with observance of

applicable standards and regulations.

The manufacturer disclaims any liability for

damage caused by non-observance of

instructions specified in this manual.

Ambient temperature and temperature of

mounting base should be within the range of

0…50˚C.

Prior to installing the controller make sure that

it will properly cooperate with hydraulic and

electrical system.

Module installation

The regulator should be screwed on to the flat

horizontal or vertical surface (e.g. boiler

housing, room wall). To screw on the

regulator use mounting holes and proper

screws. Location and spacing of mounting

holes are shown in the picture below.

The regulator must not be used

as a free-standing device.

After installation make sure that the device is

properly mounted and it is impossible to

detach it from the mounting surface.

The regulator casing provides the IP20

protection rating. The casing on the

connectors cover side provides IP00 rating,

and because of that connectors must be

unconditionally covered with the cover.

If there is a need to gain an access to the

terminals side, it is a must to disconnect the

mains voltage and make sure there is no

dangerous voltage on regulator terminals.

Temperature sensors assembly

The controller cooperates solely with

temperature sensor type CT-10, CT6-P, CT6-

W. The use of other sensors is prohibited.

At least one heating circuit temperature

sensor and one external temperature sensor

(weather sensor) are necessary to activate

the controller.

Caution: the controller is equipped

with various types of temperature

sensors! Connecting an

inappropriate sensor will cause

incorrect operation of the controller!

Sensors for heating circuits

Direct heating circuit sensor should be

installed in a hydraulic coupling. If there is no

hydraulic coupling in the system, it can be

fixed to a supplying pipe coming out of the

heat source (from boiler).

Assemble the adjustable heating circuit

sensor on a pipe after the heating circuit

pump. Insulate sensors affixed to the

external surface of the pipe with the use of

thermal insulation covering the sensor

together with the pipe.

Mounting temperature sensor: 1 - pipe, 2 –clamps, 3 -

thermal insulation, 4 - temperature sensor.

External temperature sensors

The controller cooperates only with a CT6-P

type weather sensor.

Sensor should be fixed to a coldest wall in the

building. Usually it is a north wall under the

roof. Sensor should not be subjected to direct

solar radiation nor rain. Sensor should be

fixed on a minimum height of 2m above the

ground and in a distance from windows,

chimneys and other heat sources which could

interrupt the temperature measurement (at

least 1,5m). Use a connecting cable with a

cross section of at least 0,5mm2and length of

25m. Polarity of wires is not important. Fix the

sensor to the wall with the use of screws.

Holes containing fixing screws can be

accessed by unscrewing a sensor cover.

Connecting the CT6-P external temperature sensor.

Temperature sensors checking

Temperature sensors can be checked by

measuring their resistance in given

temperature. In case of big differences

between measured resistance value and

values in table below, the sensor should be

replaced with a new one.

10 Controller functions

Information

The information menu allows you to view the

temperatures and allows you to check which

devices are currently turned on.

Frost protection mode

Frost protection mode is applicable

only to active controller work

modes Off or Auto-Eco. In Auto-

eco mode, this function is executed

only when heating circuit is turned

OFF.

Description of a frost protection mode

against the external temperature sensor

readings.

•Direct circuit (H1)

After an external temperature drop below

3°C, the time is expected in the parameter

Frost protection - delay e.g. 4 hours. If after

this time the external temperature is still

under 3°C, a direct heating circuit pump will

be activated for 30 minutes, then the

circulation water temperature will be checked.

If the water temperature in the circuit is lower

than 7°C, the controller will maintain the frost

protection setpoint temperature and display a

prompt on the display.

•Adjustable circuits (H2, H3)

After an external temperature drop below

3°C, the time is expected in the parameter

Frost protection - delay e.g. 4 hours. If after

this time the external temperature is still

under 3°C, a direct heating circuit pump will

be activated for 15 minutes, then the

circulation water temperature will be checked.

If it is higher than 7°C, the pump will stop. If

it is lower than 7°C, the pump operation will

not be interrupted and the regulator will start

to maintain the frost protection setpoint

temperature and will display a warning

message on the display.

Do not disconnect or leave the

controller in STAND-BY mode

without frost protection functions

active within a freezing hazard

period.

If heating circuits have to be off during this

period, activate Off or Auto-eco mode for

heating circuits and DHW tank instead of

turning the controller off.

Description of the frost protection mode

for DHW tank.

After the DHW tank sensor temperature drops

below 5°C, DHW tank will be loaded up to a

Minimum temperature value.

Do not disconnect the controller

within a freezing hazard period.

Solar

The controller operates a basic solar system

which loads the DHW tank. Solar system

operation requires additional temperature

sensors. No additional module is required.

Information concerning condition of the solar

system can be found in the menu:

Information

→

Solar

or on the last screen of the display which can

be accessed by clicking an arrow .

Optimize preparation of DHW in

order to take a full advantage of

heat gains from the solar panel.

Preparation of DHW can be optimized by

appropriate programming of time program for

DHW tank. Set DHW tank work mode to Auto.

Define time program for DHW tank in such

way to set insolation periods as “NIGHT”. Due

to this the boiler will not heat up the DHW

tank. Similar effect can be obtained by setting

the work mode for DHW tank to Off manually.

Loading DHW tank can be also optimized by

setting a lowest possible preset temperature

of DHW tank. The lower preset temperature of

HUW tank, the less often boiler will become

active in order to load the tank and solar

energy gain will be higher.

Installer from a service level should set the

highest possible DHW tank maximum

temperature. This will generate the maximum

heat gain. On the other hand there is a risk of

scalding with hot water and exceeding

temperature limit for a particular DHW tank!

Risk of scalding with DHW!

In order to protect against

scalding, install an additional

protective automatics, e.g.

thermostatic mixing valve.

During periods of very high insolation, there

can be a situation in which the HUW tank is

not able to absorb big amount of heat. In such

case, a solar pump transporting heat from a

solar panel to HUW tank becomes off. Due to

a risk of damaging the pump, it is turned off

only when the solar panel temperature drops.

In practice, the solar system is turned on

again the next day after the sunrise. It

indicates a normal operation resulting from

the fact that there is no possibility of

absorbing the heat surplus.

Weather control

In order for the room temperature to be

stable, must be set the weather control. The

weather control must be activated separately

for each heating circuit. The weather control

is influenced by the setting of the heating

curve and the curve parallel shift.

The heating circuit water preset temperature

is calculated basing on the temperature

prevailing outside the building. The colder it is

outside, the higher water temperature in the

heating circuit is. This relation is shown in the

controller in the form of heating curve.

The heating curve can be changed in a graph

from the system menu, within the range for

the weather preset temperature. It is a

reflection of the thermal characteristics of the

building. If the building is less insulated then

the heating curve should be greater.

Setting the heating curve: Tp –temperature preset by

weather, Tz –exterlan temperature.

Heating curve should be selected

experimentally by changing it in a few day

intervals.

During trial and error selection of

appropriate heating curve, it is

necessary to exclude influence of

the thermostat on regulator

operation (regardless of whether

the thermostat is connected or

not), by setting the parameter

Thermostat = OFF for each heating

circuit.

After choosing the proper heating curve, the

circuit preset temperature is calculated

according to the outside temperature. As a

result if the heating curve is appropriate for

the building, the room temperature remains

constant regardless of the temperature

outside.

Guidelines for selecting a proper heating

curve:

- if at dropping external temperature, room

temperature increases, the selected heating

curve is too high,

- if at dropping external temperature, room

temperature also drops, the selected heating

curve is too low,

Poorly warmed buildings require setting

higher heating curves. Whereas for well

heating buildings, heating curve will have a

smaller value.

The range of the heating curve is limited by

the minimum and maximum preset water

temperature.

Thermostat settings

In order for the room temperature to be

stable, the thermostat should be activated.

The thermostat complements the weather

control and corrects the water temperature in

the heating circuit if the room temperature is

still inadequate.

A thermostat must be activated for each

heating circuit. To do this, set the Thermostat

= ON.
