Radio heating actuator for mounting in the heating circuit manifold, 8-channel, IP20
Wireless actuators (wireless heating controllers) which, in conjunction with alre wireless room temperature sensors, realize individual room temperature control. Mainly used in renovation projects or for heating system extensions.
8-channel radio temperature actuator for installation in the heating circuit manifold. Max. 3 valve actuators per channel can be connected directly / max. 20 valve actuators in total, including pump module, one time zone per channel possible, master-slave operation, averaging with up to 8 measuring points. The top section can be removed to teach the wireless sensors in the individual rooms. This requires the use of an optional, commercially available 9 V battery. The channel selection button and a teach-in button make it very easy to teach-in the sensors.
