@ THERMASREG€ RTR-B
One-step mechanicalsingle room controller THERMASREG@ RTR-B in bi-metal technology with thermal feedback for monitoring or 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
