13.3.2 Symptom: The compressor does NOT start (space heating)
Possible causes Corrective action
The unit must start up out of its
operation range (the water
temperature is too low) If the water temperature is too low, the
unit uses the gas boiler to reach the
minimum water temperature first
(15°C).
Check and make sure that:
▪ The power supply to the gas boiler is
correctly wired.
▪ The communication cable between
the gas boiler and the indoor unit is
properly mounted.
If the problem persists after you have
conducted all of the above checks,
contact your dealer.
