Comet ZigBee is an energy saving controller compatible with ZigBee radio standard (2.4 GHz).

Comet ZigBee uses Home Automation Profile 3.0 as a radiator thermostat HVAC compatible terminal.
Depending on the mode, the energy-saving controller can be used as a heating thermostat or act purely as an actuator when control is disabled. The temperature measured by the internal sensor or the position of the valve actuator can be reported back to the corresponding gateway via ZigBee.
