Thermostatic radiator operators provide accurate and automatic control of space temperature. They are well suited to use on hot water and low-pressure steam-heated convectors, radiators, and thermostatically controlled hydronic or low-pressure heat exchangers. Five styles of thermostatic operators are available with liquid, liquid remote or low-density wax sensors.
