Comet Zero ZigBee: Smart Energy-Saving Radiator Controller

Comet Zero ZigBee is an energy-efficient controller designed for the ZigBee wireless standard. Functioning as a radiator thermostat, it operates as an HVAC-compatible endpoint using Home Automation Profile 3.0.

Depending on its mode, the Comet Zero ZigBee can serve either as a heating thermostat or, when the control function is disabled, as a simple actuator. It can report the temperature detected by its internal sensor or the position of the valve actuator back to the connected gateway via ZigBee.
