Air conditioning systems – shared use of
IR remote control and Truma CP plus VarioHeat
control panel
– Even after connecting the Truma CP plus VarioHeat control
panel, the IR remote control is available for controlling the
air conditioning system. The Truma CP plus VarioHeat con-
trol panel recognises all settings that are made using the
IR remote control on the air conditioning system. The IR re-
mote control only transmits the settings that are shown in
its display (no bidirectional communication).
– Only the time switch of the Truma CP plus VarioHeat control
panel may be used to clearly define the start and end time
of a required period.
