Room thermostat
This device is not predicted for work without room thermostat. It
must be installed in reference room. Temperature control in all
rooms of the system is done via this remote controller. Radiators
in the reference room should not be equipped with thermostat
valves, or they always must be open. All radiators in other rooms
must be equipped with thermostat valves. Connecting room
thermostat is illustrated in the Section 5.4. When installing room
thermostat in reference room follow up with thermostat manufacturer
instructions.

must be reduced using thermostat regulator. In order to prevent
freezing of heating installation, boiler temperature must not be
lower than 5
˚C. With long-term interruption of heating, the boiler
must be out switched off. (
Section7.5).
