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.
