THERMASREG
One-step mechanical single room controller THERMASREG
controlling temperatures in dry rooms, or for activating any kind of heating system as room thermostat.
For currentless open radiator valves, the cooling output from the changeover contact (normally open contact) must be connected.
At breaker contacts, a maximum of 10 valve actuators can be connected and at normally open contacts a maximum of 5 valve actuators.
