obvious defects such as loose connections or defective wiring.

THAT THE MAIN SWITCH OF THE UNIT IS SWITCHED 'OFF'.
The guidelines below might help to solve your problem. If you cannot solve the problem, consult your
installer/local dealer.
The heat pump will not run. Please check whether:
• There is supply voltage (tripped fuse, power failure).
• The operating switch on the wired controller is switched on, and whether the correct set point temperature
• has been set.
The scheduled timer does work but the programmed actions are executed at the wrong time (e.g. 1 hour
too late or too early).
Please check whether:
• The clock and the day of the week are set correctly, adjust if necessary.
If you cannot correct the fault yourself, please contact your after-sales service technician. Work on the heat
