4.3.2 Setting and adjusting setpoints
Room temperature setpoints can be…
● Set during commissioning
● Adjusted during runtime
The source can be one of the followings:
● Local HMI
● KNX tool
● Central control unit
● Siemens smartphone application PCT Go for Android
The thermostat saves the setpoints to:
● EEPROM in the form of parameters
● Runtime memory
The figure below shows the interrelation:
1)
Only required for heating and cooling applications (see Setpoints and sequences
[➙ 76])
2)
LTE-Mode: Shift is added to the local shift
3)
S-Mode: The last option selected is always used, either S-Mode input or local
operation
4)
To display the S-Mode objects of the Economy heating and cooling setpoint
(P019/P020), set the control parameter “Room temperature: Economy setpoints” to
as group object in ETS tool
Comfort basic setpoint
Comfort setpoint
