Honeywell CMT927 Wireless 7 Day Programmable Room ThermostatPlease note that this replaces CM67-RF-NG model Y6667D1086~~NEW AND BOXED~~

 
Product SpecificationThe CM927 thermostat is designed to provide automatic time and temperature control of heating or cooling systems in villas and apartments.It can be used as part of a system in conjunction with combiboilers, oil-burners and gas fired boilers, circulation pumps, thermal actuators, zone values and electric heating systems (<10A). In combination with other CM927 room units and HC60NG receivers it can be used to control multi-zone applications (up to 4 zones).The radio frequency controlled CM927 system pack consists of a room unit CMT927A 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 CM927 uses reliable RF communication technology in the 868MHz band.The CM927 extra large LCD display, dynamic text display and controls layout are identical to the CM907 wired thermostat. The unit is ideal for consumers who want reliable and precise temperature control from a modern looking, simple to program and easy-to-use product.Features CM927 can be installed without disrupting your room dr as no wiring connection is required between the room unit and the boiler. Attractive, slim, ultra-modern styling makes it ideal for location in any type of home 7-day heating programming A dynamic text display on the LCD that gives enhanced feedback to the user / installer LCD Backlighting to illuminate the display for easier viewing in low light conditions Reliable RF communication utilising 868 MHz band with 1%25 duty cycle limit to minimise communication disturbance Every room unit can be bound with several relay boxes (e.g. to control several electric heating panels) Armchair programmed Party feature that temporarily maintains a selectable constant temperature for 1–23 hours, then returns to normal operation. Day Off button follows Sundays program for 1 to 99 days, allowing selection of a different heating programwithout having to re-program the thermostat. Holiday button that provides energy savings by reducing to a constant temperature for 1 to 99 days when people are on holiday, returning to normal operation (AUTO or MANUAL) on the day of their return. EEPROM memory holds the user program indefinitely OFF position has an integral frost protection setting at minimum 5C (installer adjustable) so that pipes in the house will never freeze in winter. Communication compatibility with other Honeywell product such as HR80, HM80 and HCE80 CM927 can be used to control a zoning system with up to 4 zones Maximum system efficiency and extended boiler life due to unique zoning system synchronisation Automatic Summer / Winter time change adjusts the time automatically to daylight saving time. Standard room units and receiver boxes are used for zoning applications algorithm When used with the table top stand the room unit can be positioned anywhere in the room where RF communication is reliable 24…230V 10A resistive, 3A inductive SPDT relay provides compatibility with most domestic central heating systems reducing the need to stock many different models. The HC60NG may be surface or wallbox mounted. Installer Set-Up Mode allows extra functions to be set at the discretion of the installer to match the consumer applications and needs: Optimisation Pump Exercise Upper / Lower Setpoint Limit Adjust Temperature offset Minimum ON time Cycle rate Heat / Cool Operation Proportional Band Width Fail-safe mode for communication loss
