Wireless configurable room controller with a weekly program. The thermostat features easy installation, a clear LCD display, and simple operation. The thermostat settings allow for 4 temperature changes during one day. The design of the controller enables wireless communication between the thermostat and the relay unit, which is included in the package. It is used to control combined gas or oil boilers, circulation pumps, thermo-electric drives, zone valves, and direct electric heaters (<10A).

The wireless temperature controller set includes the CMT727A room unit and the R6660D (HC60NG) relay unit. No wiring is required for the room unit. Only wiring between the relay unit and the controlled device (e.g., boiler) is needed, and the room unit should be installed in a suitable location where radio frequency communication works reliably. The programmable room thermostat ensures a comfortable temperature when you are at home and energy savings when you are away.

Main features:

• Can be installed without interfering with room wall surfaces, as no wiring is needed.
• Attractive, slim, ultra-modern design is ideal for placement in any type of building.
• 7-day program.
• Ability to set up to 4 independent temperature changes during one day.
• Reliable RF communication using the 868 MHz band with a 1% duty cycle to minimize communication interference.
• Each room unit can be linked to several relay units (e.g., for controlling multiple heating panels).
• Programming possible "from the armchair."
• "Holiday" button saves heating energy by reducing the temperature for 1 to 99 days during absence.
• EEPROM memory retains the set program indefinitely even without power.
• OFF mode includes frost protection at a minimum of 5 °C (adjustable by the installer), so the pipes in the house never freeze.
• Ability to connect various loads: 24...230V, 10A resistive, 3A inductive, SPDT relay provides compatibility with most home heating systems.
• Information on room temperature.
• Maximum system efficiency and extended boiler life thanks to a unique zone synchronization system.
• Automatic changes between summer and winter time automatically adjusted after setting the time.
• Powered by two AA(LR6) alkaline batteries.
• The HC60NG relay unit is mounted on the wall or an electrical installation box.
• Service mode allows setting additional functions according to the installer's choice and heating system requirements.
