5.5.3 Summer/Winter compensation
– Summer/winter compensation must be enabled:
Main Index > Configuration > Configuration 2 > So-Wi comp tmp = Yes
– An outside air temperature sensor must be available:
Main Index > Configuration > Configuration 1 > Outside tmp sensor <> No.
•
Summer compensation
: Adjustment to temperature setpoint (depending on
control, supply air, room or return air) relevant to control when the outside air
temperature is high during the summer.
•
Winter compensation
: Adjustment to temperature setpoint (depending on con-
trol, supply air, room or return air) relevant to control when the outside air tem-
perature is low during the winter.

Parameter
Range
Function
Outs air tmp start
-64.0…64.0 [°C]
Outside air temperature at which point the compensation
begins to act.
Outs air tmp end
-64.0…64.0 [°C]
Outside air temperature by which the maximum (summer)
or minimum setpoint is reached.
Delta
-64.0…64.0 [K]
Maximum setpoint temperature-compensation.
Setpoint compensation is not undertaken during the summer and winter when the
outside air temperature sensor fails.
