If a setpoint (Economy or Protection) is set to OFF, the thermostat does not control
the room temperature in the corresponding mode (heating or cooling).
This means no protective heating or cooling function and thus risk of frost in
heating mode or risk of overtemperature in cooling mode!
The Economy setpoints are accessible at the service level (P11, P12); the
Protection setpoints at the expert level (P65, P66).
3.3.2 Setting and adjusting setpoints
Room temperature setpoints can be
– set during commissioning
– adjusted during runtime
The source can be
– the local HMI
– a tool
– a central control unit
The thermostat stores the setpoints
– in EEPROM in the form of parameters
– in the runtime memory
The table below shows the interrelations:
