Function
Room-temperature dependent fan compensation.
Requirement: A room or return air sensor is enabled.
Air quality-dependent fan compensation. Analog input for the sensor is
enabled.
Room humidity-dependent fan compensation.
Requirement: Room humidity sensor is enabled.
Outside air-temperature dependent fan compensation.
Requirement: Outside air sensor is enabled.
The fan is further used as a heating or cooling sequence.
No sequential impact on the fan.
Only impacts fan during the heating sequence.
Only impacts fan during the cooling sequence.
Impact on fan in both sequences.
Predefined variants for temperature setpoints:
heating setpoint and dead zone are entered.
Cooling setpoint = Heating setpoint + dead zone.
Heating and cooling setpoint is entered directly.
Base setpoint and dead zone is entered.
Heating setpoint = Base setpoint – half dead zone.
Cooling setpoint = Base setpoint + half dead zone.
Cooling setpoint and dead zone is entered.
Heating setpoint = Cooling setpoint – dead zone.
Sets whether the external setpoint acts as setpoint compensation or in
absolute terms.
Value corresponds to the comfort setpoint dependent on the switch
Tmp setpoint selection.
If the switch Tmp setpoint selection is on HtgClgSpv, the value of the
setpoint compensation corresponds to the heating setpoint and the
cooling setpoint is calculated from the difference between the entered
setpoints for heating and cooling.
Setpoint compensation.
Absolute
Selection of room temperature used for control if more than one ex-
ists.
Average.
Lowest temperature.
Highest temperature.
Room sensor 1.
Room sensor 2.
Room unit 1 (not yet implemented).
Room unit 2 (not yet implemented).
Limitation to maximum/minimum supply air temperature dependent on
room temperature.
Requirements: One cascade control is enabled.
Function minimizes draughts caused by too large a difference be-
tween supply air and room temperature.
Sets sequence of fan sequence and cooling sequence.
Requirement: Fan htg / clg is enabled.
Fan sequence before cooling sequence.
Cooling sequence before fan sequence.
