Certain problems may be resolved by checking some fundamental points. Check using the list below before requesting servicing.
Warning: When the controller is switched on, control will only take effect after a few minutes of system initialisation. (the terminal
segments come on approximately every 2 seconds)
Upon a mains power cut:
1. When the power returns, the controller restarts in Comfort mode in all cases:
→ However, it does not store:
- The setpoint override (returns to the midpoint)
- The ventilation speed (returns to Auto)
2. Error message: diagnostic d07 gives the controller's Alarm state.
