P09 ≥ P10
Cooling setpoint adjustable 25…40 °C
Heating setpoint adjustable 5…21 °C
Use control parameters P11 and P12 to adjust the Economy mode setpoints.
The heating setpoint is factory-set to 15 °C, and the cooling setpoint to 30 °C.
Use control parameters P65 and P66 to adjust the Protection mode setpoints.
The heating setpoint is factory-set to 8 °C (frost protection) and to OFF for cooling.
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 over-temperature 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

– set during commissioning
– adjusted during runtime
The source can be via
