R3... is an electro-mechanical room thermostat intended for wall mounting. The R3 thermostat contains a pair of gas-filled bellows with a stainless steel membrance which reacts to changes in temperature by generating a movement which is transmitted to a change-over relay. The R3 thermostat can control a heating or cooling function. The R33 and R34 have a LED for activated output indication.
