Unlike normal room
thermostats, the ORT-01
varies the heat output of the
Opentherm condensing boiler
to which it is connected. This
adds signicantly to the boiler
eciency by ensuring that the
boiler keeps in economical
condensing mode whenever
possible.
Daily use is as easy as setting the thermostat dial to the
required setting, the advanced electronics and software within
the thermostat establish two-way communication with the
Opentherm boiler to ensure optimal operation.
In addition to the room temperature control, the ORT-01 also
incorporates a feature which, dependant on boiler type, allows
the domestic hot water store in the boiler to be kept hot or to be
turned o, for example when on holiday. To select hot water o,
simply turn the thermostat knob to the holiday position .
