Resideo T100C1026 Thermostat Radiator Actuator W/Remote Sensor & Dual Capillary

The Resideo T100C1026 Thermostat Radiator Actuator is a device for regulating the temperature of each radiator in a two-pipe steam or hot water heating system. It has a remote sensor and two capillary tubes for accurate temperature control. This actuator can be used with both the V100 and V2000 radiator valves, which means that it can be used in any heating system. The remote sensor records the temperature of the room and sends it to the actuator. It then controls the radiator valve to open or close to maintain the correct temperature.
