The HERZ-Actuator 230 V / 24 V is a thermoelectric valve drive for opening and closing valves on heating circuit distributors of concealed floor heating and cooling systems. The actuating drive is switched on via an electrical contact, e.g. from a room thermostat, and starts opening or closing the thermostatic valve. The actuating movement is accomplished by an electrically-heated expansion element. When the heating current is switched off, the valve closes or opens respectively. The HERZ actuating drive is maintenance-free and offers silent operation.
The main field of application is the energy-efficient individual room temperature control in the range of building management systems and home automation. The HERZ-Actuator 230 V /24 V is controlled by a 230 V / 24 V room thermostat with two-point output or pulse-width modulation.
