Application
The actuator can be installed on all HERZ-TRVs with M28x1,5.
Function
This energy saving controller for radiators can be used to control room temperature an the basis of time. The actuator moves
a valve, thereby allowing the amount of heat flowing to the heating appliance to be controlled.
The controller is compatoble with the most HERZ TRVs. The large illuminated display ensures user-friendly operation. A wire-
less receiver allows the device to receive commands from taught-in system components.
