in the order shown below:
– Automatic mode (control in dependence on the adjusting weekday program → see 5.4 / 5.5)
– Comfort mode (permanent control targeted at maintaining the adjusted comfort temperature
→ see 5.4)
– ECO mode (permanent control targeted at maintaining the adjusted ECO temperature
→ see 5.4)
– Standby mode (antifreezing mode)
In "standby" mode, the controller activates the antifreezing function each time the temperature value
measured by the internal or the activated external sensor falls below a level of approx. 5°C. This
antifreezing function helps prevent rooms from cooling down thoroughly, thus protecting against the
occurrence of frost damage.
