4.2 Mode change by keyboard

It is possible to switch from heat pump mode to

chiller mode only by switching oﬀ the unit.

If the unit is in heat pump mode, press the

button to place it in

Standby

.

Then press to switch it on again in chiller

mode.

Vice versa, if the unit is in chiller mode, press

to place it in Standby, and then press to

turn it back on in heat pump mode.
