Honeywell CM67RF Wirefree Chronotherm PDF Product Specification Sheet Manual

The CM67RF Chronotherm 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 gas and oil boilers, circulation pumps, variety of valves and actuators or electric heating systems (<10A). The radio frequency controlled CM67RF system consists of a room unit T6667C and relay box R6660C (HC60). No wiring to the room unit is required. Installer needs to wire only the relay box to a controlled device (e.g. boiler) and mount the room unit in a suitable location where the RF communication is reliable. The CM67RF display, buttons and slider layout are identical to CM67 ‘wired’ chronotherm The unit is ideal for consumers who want reliable precise temperature control from a simple to program easy to use product.

FEATURES
• Attractive slim styling makes it ideal for location in any home.
• Proven narrow band, multi-frequency synthesiser based technology for communication jamming avoidance
• As no wired connection needs to be provided between room unit and boiler, CM67RF can be installed without disrupting your room decor 7-day program
• 6 daily independent time and temperature level changes let you set 6 time and temperatures pairs to suit your life style.
• Temporary setpoint temperature change overrides the programmed temperature till the next switch point.
• 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 CM67.

• EEPROM memory holds the user program permanently even when batteries are removed.
• 24…230V 10A resistive, 3A inductive SPDT relay provides compatibility with most domestic central heating systems without stocking many different models.
• The wall-mounted holster allows removal of the CM67RF from the wall for armchair programming.
• The HC60 may be surface or wallbox mounted.
• Frost protection is ensured when the slider is in the OFF position. Frost protection setpoint may be adjusted by installer (minimum setting 5 C).
• Installer Set-Up Mode allows extra functions to be set at the discretion of the installer to match the application :
• 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
• Every room unit can be bound with several relay boxes (e.g. to control several electric heating panels)
• CM67RF can be used with Automatic Time Setting module (Q6667B1007)

INSTALLATION The CM67RF is a radio frequency device and for the best performance should be installed in an open space. Leave at least 30cm distance from any metal objects including wall boxes and at least 1 metre from any other electrical equipment e.g. radio, TV, PC etc. Do not mount on metal wall boxes. It is recommended that the R6660C relay box is installed before commencing with the room unit installation (refer to appropriate Installation Guide).

WIRING The R6660C relay box is designed for fixed wiring only and must be installed in accordance with latest l.E.E. regulations. Ensure the wiring connection to the supply is via a fuse rated at no more than 10 amps and a Class “A” switch (having contact separation of at least 3 mm in all
poles).
