Functions
Function
Present temperature used for control.
Eight supply air, room or return temperature depending on
the setting and control type.
Present calculated room or supply air setpoint for cooling.
Present calculated room or supply air setpoint for heating.
Present calculated supply air setpoint in cooling for a cas-
cade control.
Present calculated supply air setpoint in heating for a cas-
cade control.
Present external setpoint or setpoint compensation.
Setpoint compensation for winter operation for:
Tmp control mode = RmSplyC Su (Room supply air cas-
cade control in summer, pure supply air control in winter).
or
Tmp control mode = RtSplyC Su (return supply air cas-
cade control in summer, pure supply air control in winter).
The room setpoint for cascade control, active in the sum-
mer, are active (summer - winter changeover).
During winter, these room setpoints must be adapted to
the supply air control.
Comfort based setpoint. Only available when Tmp stpt
selection = +/-Half degree Celsius.
Comfort cooling setpoint. Only available when Tmp stpt
selection = Htg/Clg or Clg-degrees Celsius.
Comfort heating setpoint. Only available when Tmp stpt
selection = Htg/Clg or Htg-degrees Celsius.
Comfort dead zone. Only available when Tmp stpt selec-
tion = Clg-degrees Celsius or Htg+degrees Celsius or +/-
Half degree Celsius.
Economy base setpoint. Only available when Tmp stpt
selection = Spv+Halfdegree Celsius.
Economy setpoint for cooling. Only available when Tmp
stpt selection = Htg/Clg or Clg-degrees Celsius.
Economy setpoint for heating. Only available when Tmp
stpt selection = Htg/Clg or Htg-degrees Celsius.
Economy dead zone. Only available when Tmp stpt selec-
tion = Clg-degrees Celsius or Htg+degrees Celsius or +/-
Half degree Celsius.
Setpoint for Heating 2, El Heating 2, Cooling 2 if config-
ured as stand alone.
Lower allowable supply air temperature for pure room or
return air control with additional available supply air sen-
sor. Limited control of the cooling setpoint occurs if the
supply air temperature < Supply tmp min. The heating reg-
ister is started if this is not enough.
Highest allowable supply air temperature for pure room or
return air control with additional available supply air sen-
