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.

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 stan d 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)
