can be controlled, whereby the setpoint for this measurement point is lowered at a dehumidification
requirement. The lowest setpoint can be set in the access level 5. This function is only possible
when:
•
2 heating batteries and 1 cooling battery are present
•
a saturation temperature sensor is present
•
return air cascade, supply air or room cascade is set as control strategy
Setpoint Description Default
Saturation temp. Minimum saturation temperature 14 °C
Table 14: Saturation temperature setpoint
14.2.3 Supply air limitation
The supply air temperature is always limited:
•
the supply air setpoint cannot exceed the limits, if the cascade control is active
•
no setpoint is allowed to exceed the limits, if the supply air control is active
•
the supply air temperature is limited by separately adjustable controller, if the return air control
and room control are active
Setpoint Description Default
Min supply air temp. Minimum limit for the supply air setpoint 16 °C
Max supply air temp. Maximum limit for the supply air setpoint 35 °C
Table 15: Supply air temperature limits
14.2.4 Summer / winter compensation
Via the summer compensation, cooling setpoints can be raised at high outside temperatures to
keep the difference between outdoor and indoor temperature low or to save cooling energy; heating
setpoints are not affected.
Via the winter compensation, heating setpoints can be raised or lowered at low outdoor tempera-
tures; cooling setpoints are not affected.
Summer compensation 1/4
Start 25.0°C
End 30.0°C
Delta 5.0°C
Calculated 0.0°C
