In Auto timer mode, the thermostat automatically switches between Comfort
and Economy mode according to the time schedule.
In Comfort mode, the thermostat maintains the room temperature on the setpoint which can be readjusted using the + and – buttons.
In Economy mode, the room temperature is maintained at a lower or higher
setpoint, thus saving energy and money.
Adjust parameters P11 and P12 to change the preselected setpoints.
The thermostat can be set to Economy mode either by pressing the operating
mode button if enabled (P02 = 2), or via an external signal (switch) such as
window contact, keycard or presence detector.
In Protection mode, the plant stops operating. However, if the room temperature
drops below 8 °C, heating is switched on to protect the room against frost.
Your HVAC installer can change the frost protection limit and set a heat protection limit as needed:
Changes made by installer: Frost protection: ........... ˚C
Heat protection: ........... ˚C
Change from heating to cooling mode
