Setting Dial

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 .
