The thermoelectric actuators are used for opening and closing valves in heating, air conditioning, and ventilation systems. They are available in 230 V and 24 V variants with a detachable connection cable (1m) in a splash-proof housing with stroke display. The actuators are primarily used for individual room temperature control to drive radiators, convectors, and cooling ceilings. For control (2-point regulation or pulse width modulation), the Electronic Switching Actuator ES/S or the Electronic Relay ER/U in combination with the Universal Interface US/U and a room temperature controller is suitable. The plug-in mounting on valves and heating circuit distributors is done using the valve adapter VA/Z XX.1.
