6.1.3 Determining the setpoint value
6.1.3.1 Calculating the setpoint value in heating operation
See:
Base setpoint value and current setpoint value
Table 31: Current setpoint value during heating
Operating mode Current setpoint value
Comfort Base setpoint value +/- setpoint value offset
Standby Base setpoint value +/- setpoint value offset – reduction in standby mode

Parameters Setting
Setpoint values Basic setpoint value after
loading the application 21 °C
Reduction in standby
operating mode
(during heating) 2 K
Maximum valid setpoint
value offset +/- 2 K
The set point value was previously increased by 1 K via object 1.
Calculation:
Current setpoint value
= base se setpoint offset
= 21 °C + 1K
= 22°C
If operation is switched to standby mode, the
current setpoint value is calculated as follows:
Current setpoint = base se setpoint offset – reduction in standby mode
= 21 °C + 1K – 2K
= 20 °C
