Product Description
The CM721/CM727 thermostat is designed to provide automatic time and temperature control of heating systems in houses and apartments. It can be used as part of a system in conjunction with combi- boilers, oil-burners and gas fired boilers, circulation pumps, thermal actuators, zone valves and electric heat systems (<10A).
The radio frequency controlled CM721/CM727 system pack consists of a room unit CMT721/CMT727 and a relay box R6660D (HC60NG). No wiring to the room unit is required. The installer only needs to wire the relay box to the controlled device (e.g. boiler) and mount the room unit in a suitable location where RF communication is reliable. The CM727 uses reliable RF communication technology in the 868MHz band.
