HONEYWELL CM67 Programmable Thermostat
The CM67 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 combi boilers, oil- burners and gas fired boilers, circulation pumps, thermal actuators, zone valves and electric heat systems (<8A).
The CM67 is designed with the installer in mind and includes a moulded backplate with trunking guides and wiring breakouts to make installation quick and easy. The CM67 display, buttons and slider layout are based on the same simple programming philosophy used on the acclaimed CM51 product. 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.
- 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 programmed temperature override to temporarily override 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.
- Holiday button provides energy savings by reducing the temperature for 1 to 99 days when people are on holiday, returning to normal operation (AUTO or MANUAL) on the day of return.
- EEPROM memory holds the user program indefinitely.
- Telephone Interface (optional) can be fitted to the CM67 to allow switching between programmed mode (slider position) and fixed set-point of 21 oC.
- 24…230V 8A resistive, 3A inductive SPDT relay provides compatibility with most domestic central heating systems without stocking many different
models - Surface or wallbox mounting options, trunking guides and wiring breakouts simplify installation.
- OFF position on the slider has an integral fixed frost protection setting at minimum of 5°C (installer adjustable) so that pipes in the house will never
freeze in winter. - Installer Set-Up Mode allows extra functions to be set at the discretion of the installer to match the consumers applications :
- Optimisation
- Pump Exercise
- Upper / Lower Setpoint Limit Adjust
- Temperature offset
- Minimum ON time
- Cycle rate
- Heat / Cool Operation
- Proportional Band Width
- CM67 has provision for add-on modules to allow the installer to sell additional features during or after the first CM67 installation, giving the installer an
additional sale. - Outside Temperature Sensor accessory (optional) can be fitted to the CM67 to display the external temperature.
- Remote Temperature Sensor (optional) can be fitted to the CM67 to control the temperature from another room.

DIMENSIONS
INSTALLATION
LOCATION
The CM67 Chronotherm is the temperature control element in the heating/cooling system and MUST be located in a position with good air circulation at average room temperature on an inside wall 1.5 metres above the floor level. Do not position the CM67 Chronotherm near sources of heat (radiators, hot air vents, TV or lights), near doors or windows, or in direct sunlight.
MOUNTING
The CM67 Chronotherm can be mounted directly on the wall surface or on an electrical wallbox.
WIRING
The CM67 Chronotherm 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 8 amps and a Class “A” switch (having contact separation of at least 3 mm in all poles).
IMPORTANT
- The installer must be a trained service engineer
- Disconnect the power supply before beginning installation
