2. Functions
2.1 Overall functions
2.1.1 General
This section describes special functions that relate to the application as a whole.
Main menu > Overall functions.
Parameter Value Function
Summer-winter calculation – Summer
– Winter
Displays present status for summer and winter
operation.
Go to page to parameterize summer/winter
changeover.
Manual operation
– Auto.
– Manual
Displays whether one of the outputs is not in auto
mode (intervention via HMI), a sensor is out of
service or the manual operation mode is not on
auto.
Go to page with all digital inputs, e.g. to set the
alarm class for enabled manual alarm.
– Auto mode: No element in manual mode or out of
service.
Manual mode: At least one element is in manual
operation or out of service.
Enable manual alarm
– No
– Yes
Enables an alarm if in Manual mode = Manual.
– No alarm will trip.
– Alarm enabled.
Enable comm. test The function is not available.
Communications test The function is not available.
2.1.2 Summer/winter changeover
None.
It decides whether the plant is operating in the summer or winter mode based on
various options (hardware input, date, temperature). This information is required (as
an option) to shut down humidification in summer, to changeover the Combi Coils
and to changeover temperature control (Tmp control mode = RmSplyC Su or
RtSplyC Su).
A hardware input enabled for the changeover (Main menu > Configuration >
Configuration 1 > Su/Wi input = Yes) has the highest priority (Signal 1 = Summer).
The temperature or date can affect the changeover depending on parameterization.
Both criteria must be met when both are enabled. There will be no changeover and
the plant will operate continuously in the winter mode if no criterion is enabled.

2.2.2 Supply air/extract air fan control
Fans can be directly controlled, pressure-controlled, flow controlled or controlled as
master-slave. Common or separate outputs are used depending on the
configuration.
Fans may include an alarm and/or active feedback contact.
Up to 3 setpoints per fan can be defaulted for controlled fans and achieving the
setpoints can be monitored.
You can influence the fan stage (speed) by room temperature, air quality, humidity,
outside air temperature or supply air temperature.
Operating hours are recorded separately. A message can be triggered upon reaching
a certain number of operating hours for the supply air fan.

2.3 Time switch program - details
This section describes the functions and entries for time switch programs and
calendars.
Possible entries vary depending on the configuration. It is set in Configuration 1:
Main menu > Configuration > Configuration 1 > TSP function.
Main menu > Configuration > Configuration 1 > TSP stages
The auxiliary time switch program has the set entries Off and On:
Main menu > Configuration > Configuration 2 > Aux.TSP.
When no elements with a higher priority (e.g. Manual Operation <> Auto) are enabled,
the plant can be switched Off or any stage (for frequency controlled fans to the given
stage setpoint) using the time switch program. A maximum of 6 switching time
entries are possible per week.
The calendar Fix Off (in operating mode only) overrides the calendar exception and
this in turn overrides the normal time switch program. Up to 10 periods or exception
days can be defined for each calendar.
TSP function=Step+tmp: Both the fan stage setpoint and the temperature setpoint
(Comfort/Economy) are determined by the time scheduler.

2.7.1 General
Displays only functions that are enabled in Configuration 1 or Configuration 2. All
other functions are hidden.
Main menu > Unit > Temp. control
Parameter Function
Act controlled tmp. Present temperature is used for control. Either supply air, room air or extract air
temperature, depending on the setting and control type.
Temp setpoints Go to setpoint page with all setpoints affected by temperature control,
e.g. comfort, economy, cascade min max, deviation alarm, summer-winter
compensation..
Cascade controller Displays heating and cooling setpoint. Go to cascade controller page with
detailed settings.
Min/max ctrlr sply Go to page for min/max ctrlr sply to parameterize the minimum and maximum
limit controller. You can use the existing supply air sensor to limit the minimum or
maximum allowable supply air temperature if purely room or return air control is
active..
Hrec damper Present value of the mixed air damper control. Go to parameter page for mixed
air damper control.

parameter page for cooling register control.
Extra heating Present value for heating register for an extra register. Go to parameter page for
heating register control.
Extra el heating Present value for electric heating register control for an extra register. Go to
parameter page for electric heating register control.
Extra cooling Present value for cooling register control for an extra register. Go to parameter
page for cooling register control.

Main menu > Unit > Temp. control > Temp. setpoints
Parameter Value Function
Pres.ctrd tmp --- Present temperature used for control.
Either supply air, room air or extract air temperature,
depending on setting and control type.
Pres.setp.clg --- Present calculated room or supply air setpoint for cooling.
Pres.setp.htg --- Present calculated room or supply air setpoint for heating.
Pres.sasetp.clg --- Present calculated supply air setpoint for cooling using
cascade control.
Pres.sasetp.htg --- Present calculated supply air setpoint for heating using
cascade control.
External setpoint --- Present external setpoint or setpoint compensation.
Supply air comp. -10.0…10.0 [°C] Setpoint compensation for winter operation for:
Tmp control mode = RmSplyC Su (Room supply air cascade
control in summer, pure supply air control in winter).
or
Tmp control mode = RtSplyC Su (return supply air cascade
control in summer, pure supply air control in winter).
The room setpoint for cascade control, active in the
summer, are active (summer - winter changeover).
During winter, these room setpoints must be adapted to
the supply air control.
Comfort heating 0…99 [°C] Comfort based setpoint for heating. Only available when
Tmp stpt selection = +/-Half Dz.
Comfort dead zone 0…20 [°C] Comfort dead zone. Only available when Tmp stpt
selection = Clg - degrees Celsius or Htg + degrees Celsius
or +/- Half Dz.
Setp.extra sequ. 0…99 [°C] Setpoint for extra heating, extra electric heating, extra
cooling if configured as stand alone.
Setp.min sply.temp 15.0… Setp.max
supply temp [°C]
Lowest permissible supply air temperature for pure room
or extract air control with additional available supply air
sensor. Limited control of the cooling setpoint occurs if the
supply air temperature < Setp.min sply.temp. The heating
register is started if this is not enough.
Setp.max sply.temp Setp.min supply
temp … 50.0 [°C]
Highest permissible supply air temperature for pure room
or extract air control with additional available supply air
sensor. Limited control of the heating setpoint occurs if the
supply air temperature > Setp.max sply.temp.
Setp.min sply.temp -64.0 …99.0 [°C] Lowest permissible supply air temperature for cascade
control.
Setp.max sply.temp -64.0 …99.0 [°C] Highest permissible supply air temperature for cascade
control.
Delta flt.maxlim. 0.0…64.0 [°C] Maximum difference between supply air and room air
temperature for heating when Floating Min/Max is enabled
(Configuration 2).
Delta flt.minlim. 0.0…64.0 [°C] Maximum difference between supply air and room air
temperature for cooling when Floating Min/Max is enabled
(Configuration 2).
Fan htng deadz 0…20 [°C] Controller dead zone: Setpoint = Supply air heating
setpoint – dead zone.
