Home Matic Wireless Radiator Valve Drive. Highlights & details. Frost-protection function. Quietly operating actuator. Simple installation. Description. The understated & elegant Home Matic-valve operating mechanism is clearly less protruding in the room in comparison to a traditional mechanical thermostat head. This reduces the risk of accidental damages & physical injuries. Once installed, the battery-run radio actuator works without attracting any attention & quietly. A digital display informs about valve setting, radio reception & battery status. So that, you are well informed anytime, if required. The low-power technology allows a battery life-span (under typical circumstances of usage) of up to 2 years! The use of standard mignon-batteries keeps the battery costs extremely low. If you were to miss replacement of batteries inspire of a (visual & acute) prior warning period then there is still the possibility to manually control valve with a control-pin integrated to the housing. Quickly & easily installed. No cable or power connection is required at all. The replacement of old valve heads with the electronic actuator is simply easy & can also be done without any technical expertise & less handling. Discharging of water, ventilating etc. is not necessary here. Programming of wall thermostats is simple & intuitive. Through adapter sets available as accessory is suitable for all available heat valves. Features. LCD 8 x 12 mm. (backlit). Connection thread: M30 x 1.5. Battery life-span: up to 2 years.
