This thermal actuator is matching to zone valves and provides a two-point (OPEN/CLOSE) control for heating and air-conditioning systems. The thermal actuator keeps the valve shut in a de-energised state; it is equipped with a “First-Open” function and a function indicator.
The thermal actuator is plugged on to a valve adapter (VA1) via bayonet closure. If requested by the customer, it can be supplied with an auxiliary switch for ON/OFF control of the circulating pump.
