The remote controller gives immediate feedback to the indoor unit
and by doing so it matches in a smart way the unit performance to
the demanded space heating requirements. In this way there is no
frequent start/stop of the unit or there are no too big temperature
fluctuations in the to be heated rooms. This remote controller has
also a smart logic functionality which controls the combined space
heating and domestic hot water demand (e.g. if room temperature
drops more than 3°C during domestic hot water operation, the unit
will automatically switch back to space heating). The main remote
controller (C1) is installed in the living room and can access all
settings (master). The second remote controller (C2) can not access
schedule and parameter settings (slave).

Space heating and domestic hot water heating with a single remote
controller installed with the unit, and the external room thermostat
installed in the living room.
Optionally the Rotex room thermostat RKRTR or RKRTW
can be connected to the Rotex system. Rotex can not
guarantee neither good operation nor reliability of the
system if another thermostat is used. For those reasons
Rotex can not give warranty of the system in such case.
