IMPORTANT!
During functioning in heat pump heating mode, the unit performs defrost cycles to elimi-
nate any ice that might form at low temperatures inside the outdoor unit. During defrost-
ing, the indoor fan is automatically switched off and does not start up again until defrost-
ing has been completed.

Controls

The unit can be used with an infra-red remote control, or with the cabled "Room Controller"
or "Zone Manager" remote controls.
See the remote control's own manual for information on how to operate the infra-red or
