Function
Present controller output for cooling setpoint or
dehumidification setpoint.
Present controller output for heating setpoint or
humidification setpoint.
Present actual value (input value) for the control-
ler.
Cooling or dehumidification setpoint from the
program.
Heating or humidification setpoint from the pro-
gram.
Maximum supply air temperature or humidity.
Minimum supply air temperature or humidity.
Set compensation for a room load. Calculates
the present controller outputs as follows:
− Control output clg = Internally calculated Con-
trol Output clg + Load compensation
− Control output htg = Internally calculated
Control Output htg + Load compensation
Displays setpoint variants in the program (Con-
figuration 2 >Tmp stpt selection or Hum stpt se-
lection).
From the entry of calculated dead zones. (Dis-
plays dead zones: Configuration 2 >Tmp stpt
selection or Hum stpt selection).
Enable controller:
− Controller disabled.
− Controller enabled.
Controller fault status (e.g. faulty sensor signal):
− No error.
− Error pending. Does not trigger an event,
since the cause of a control fault must be re-
corded separately (e.g. room sensor fault).
