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). There is no remote controller near the
unit. During service maintenance an additional remote controller
can be connected by a service person.

reliability of the system if another thermostat is used.
For those reasons Rotex can not give warranty of the
system in such case.
