6.10.2 set point calculation in cooling mode
Current set point during cooling:
Operating
Mode
Current set point
Comfort
Base set point + set point offset + dead zone
Standby
Base set point + set point offset + dead zone + increase in standby mode
Night
Base set point + set point offset + dead zone + increase in night mode
Frost/heat
protection
configured set point for heat protection mode
Example: Cooling in comfort operating mode.
The room temperature is too high, the controller has switched to cooling mode

Heating set points
Maximum valid set point offset
+/- 2 K
Base set point after loading the
application
21°C
Cooling set points
Dead zone between heating
and cooling
2 K
Increasing in standby mode
(during cooling)
2 K
The set point was previously lowered by 1 K on the device.
Calculation:
Current set point = base set point + set point offset + dead zone
= 21 °C - 1 K + 2 K
= 22 °C
Changing to standby mode causes a further increase in the set point (energy saving), resulting
in the following set point.
set point = base set point + set point offset + dead zone + increase in standby mode
= 21 °C - 1 K + 2 K + 2 K
= 24 °C
