Multi-zone Thermostat Q8RF

Description

Computherm Q8 RF multi-zone room thermostat

it is suitable for ordering a heater or air conditioner, being compatible with most central heating boilers sold in Romania.

It can be easily connected to any boiler or air conditioner, if it is equipped with connection terminals, with the help of a 2-wire cable regardless of whether the control voltage is 24 V or 230 V.
The basic equipment of the appliance contains 2 thermostats and 1 receiver. If necessary, this assembly can be completed with 2 more thermostats.
The reception unit notices the start / stop signals of the thermostats, the central heating control (or the air conditioner), and also controls the closing / opening of the zone valves (maximum 4 zones - 230 VAC electric current and max. 2A resistive / 1A inductive) of the heating system.
By dividing the heating system into zones, they can work individually or together. Thus, only the rooms that are used at that time will be heated (eg the living room and bathroom during the day, and the bedroom at night).
The communication between the thermostats and the receiver is made by radio waves (radio frequency), so it is not necessary to make wiring between them.
The COMPUTHERM Q8 RF radio frequency thermostat is mobile.
The range is about 50 m in open ground and about 30 m in a building, being influenced by the structure of the building. The range is much shorter if the waves encounter metal structures, reinforced concrete, etc.
