7.8 - SPECIAL OPERATING FEATURES
• Water circulating pump control:
- the pump is actuated when the unit operating,
- the pump is stopped when the unit is stopped. The shut-down of the pump is delayed 1 minute after the compressor stops,
- the unit's electronic control features a frost protection device that automatically starts the water circulating pump
depending on the outside temperature (threshold: 0
°
C), even if the unit is turned off.
In the event of a faulty outside temperature sensor, circulating pump operation is forced, for safety reasons.
The "Water output" alarm (E41) stops the circulating pump when this alarm shifts to manual reset. In the event of a fault,
the alarm report is actuated.
