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
field settings (slave).

Application 3
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.

There is only a room thermostat on/off control. There is no smart
logic functionality for space heating. When there is simultaneous
demand of space heating and domestic hot water, the domestic
hot water operation is performed according to the minimum and
maximum timer operation.
