FEATURES
•CM67RF MV can be installed without disrupting your room décor – no wired connection required between the room unit and the boiler
•Reliable RF communication utilising 868,3 MHz band with 1 % duty cycle limit to minimise communication disturbance
•CM67RF MV can be used to control directly mixing valves depending on the room setpoint temperature
•Maximum system efficiency and extended boiler life due to unique zoning system synchronisation
•Up to 4 CM67RF MV can be bound with one HC60NG for boiler feedback heat on demand
•Suitable for any room décor due to subtle styling
•Easy to program – user friendly interface allowing 7- day programming to match variety of lifestyles
•Armchair programmed
•Non volatile memory holds the user program permanently even when batteries being replaced
•Party button to temporarily maintain (or adjust) the current temperature for 1-23 hours
•
Day Off button copies Sunday’s program into tomorrow or today to allow a rest day program without having to re-program the CM67RF MV
•
Holiday button provides energy savings by reducing the temperature for 1 to 99 days when homeowner is on holiday, returning to normal operation (AUTO or MANUAL) on the day of return.
CM67RFMV
WIREFREE CHRONOTHERM
PRODUCT DATA
GENERAL
The CM67RFMV Chronotherm is designed to provide automatic time and temperature control of heating or cooling applications. It can be used to control directly mixing valves for individual zoning control. The Chronrotherm is communicating with the universal mixing valve controller HM80 depending on the deviation of the room temperature and room temperature setpoint the mixing valve will be closed or opened.
In combination with other CM67RFMV Chronotherms and one HC60NG receiver it can be used to control the boiler depending on the heat demand (up to 4 CM67RFMV ).
No wiring to the room unit is required. The installer needs to wire the universal mixing valve controller HM80 only to the controlled device mixing valve and mount the room unit in a suitable location where RF communication is reliable.
The CM67RFMV uses reliable RF communication technology in the 868,3 MHz band.
The unit is ideal for consumers who want reliable and precise temperature control from an easy-to-use product.
FEATURES continued
•When used with the table top stand the room unit can be positioned anywhere in the room where RF communication is reliable
•Installer Set-Up Mode allows extra functions to be set at the discretion of the installer to match the application :
•Pump after running time
•Mixing valve running time
•Upper / Lower Flow Temperature Limit Adjust
•Upper / Lower Setpoint Limit Adjust
•Forced operation pump
•Forced operation mixing valve
•Temperature offset
•Heat / Cool Operation
•Fail-safe mode for communication loss
•Frost protection is ensured when the slider is in the OFF position.
•CM67RFMV can be used with Automatic Time Setting module (Q6667B1007)
