Electronic room dual–circuit chronothermostat (black)

(VT.AC634.B) A distinctive feature of VT.AC.634 dual-circuit chronothermostat is the possibility of independent control of both the radiator heating system and the underfloor heating system.

If the room temperature is too low, the thermostat uses two systems to heat it as quickly as possible: underfloor heating and radiators. When the temperature becomes comfortable, the thermostat turns off the radiators and maintains the temperature only with the underfloor heating. If the temperature continues to rise and exceeds the comfortable range, the thermostat turns off the underfloor heating system. The systems are switched on in reverse order.

The electronic dual-circuit chronothermostat implements two options of heating devices control: an integrated air temperature sensor and an external sensor.

The thermostat allows weekly programming of temperature conditions with a breakdown of each day into six time periods.

Actuators control is realized through electromagnetic relays with a three-pin output to the terminal post of the thermostat. It makes it possible to work with both normally closed and normally open servos.

Power supply voltage of the device: 220 V (50 Hz). Maximum switching current for each circuit: 3 A.

This chronothermostat is made in a black case.
