Quiet mode
The unit has a quiet mode functionality for which 3 levels can be selected:
[8-03]
= 1 low noise level 1 (default)
[8-03]
= 2 low noise level 2
[8-03]
= 3 low noise level 3
Activating this quiet mode is done by pushing the QUIET MODE button on the remote controller or
through the schedule timer.
[8-04]
Freeze-up prevention
The unit has a freeze-up prevention functionality for which 3 levels can be selected:
[8-04]
= 0 prevention level 0 (default: no prevention)
[8-04]
= 1 prevention level 1
[8-04]
= 2 prevention level 2
The freeze-up prevention is only active when the unit is in thermo OFF condition. If prevention level
1 is enabled, the freeze-up prevention will start if the outdoor ambient temperature <4°C and if
leaving or return water temperature <7°C. For prevention level 2, the freeze-up prevention will start
as soon as the ambient temperature <4°C.
For both cases the pump will operate and if leaving or return water <5°C for 5 minutes the unit will
start up to prevent too low temperatures.
It is advised to enable freeze-up prevention if the indoor unit is located in a colder ambient room (e.g.
garage, ...) to prevent water freeze-up.
