WebThe electro-thermal actuator is designed to control the flow of a hot water pipe to control indoor temperature. When the actuator is on, the sensor inside will control the flow of hot water to the device that heats the room (ex. fan coil). When the actuator is closed,it will automatically be set to the off position. WebThe operation of a thermostatic actuator is based on the principle that there is a significant change in the volume of paraffin wax as it goes through a phase change from solid-to-liquid; liquid-to-solid as the wax temperature increases and decreases.
