Room temperature setpoints can be:
- Set during commissioning
- Adjusted during runtime
Setpoint for Comfort
The source can be:
- Local HMI
- BACnet commissioning tool (RDF4..BN)
- Modbus commissioning tool
- Modbus client device
The thermostat saves the setpoints after power failure.
The figure below shows the interrelation:
1) Only required for heating and cooling applications (see Setpoints and sequences)
Room temperature via bus
The current setpoint (used by the thermostat for temperature control) is available on the BACnet/Modbus for use in the central control unit.
General note:
- Changes via the local HMI or tool have the same priority (last one wins).
Notes on setpoint adjustment
- Minimum room temperature setpoint for Comfort can be adjusted via P20 (default: 5 °C) and maximum setpoint via P21 (default: 35 °C). If two parameters are adjusted, "Setpoint for Comfort" is updated accordingly.
