HONEYWELL CM61RF Programmable Thermostat

INTRODUCTION

The CM61RF Chronotherm is designed to provide automatic time and temperature control of heating or cooling systems in villas and apartments. It can be used as a part of system in conjunction with gas and oil boilers, circulation pumps, variety of valves and actuators or electric heating systems (<10A). The radio frequency-controlled CM61RF system consists of a room unit T6661C 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 CM61RF display, buttons, and slider layout are identical to CM61 ‘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, CM61RF can be installed without disrupting the room decor
• 6 daily independent time and temperature level changes let you set 6 time and temperature pairs to suit your life style
• Temporary setpoint temperature change overrides the programmed temperature till the next switch point
• 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 even when the batteries are removed
• OFF mode has an integral fixed frost protection setting at a minimum 5°C (installer adjustable) so that pipes in the house will never freeze in winter.
• 24…230V 8A resistive, 3A inductive SPDT relay provides compatibility with most domestic central heating systems without stocking many different models
• The wall-mounted holster allows the removal of the CM61RF from the wall for armchair programming
• The HC60 relay box may be surface or wall box mounted
• Frost protection is ensured when the slider is in the OFF position. Frost protection setpoint may be adjusted by installer (minimum setting 5oC)
• Installer Set-Up Mode allows extra functions to be set at the discretion of the installer to match the consumers applications:
• Optimization
• Pump Exercise
• Upper / Lower Setpoint Limit Adjust
• Temperature offset
• Minimum ON time
• Cycle rate
• Heat / Cool Operation
• Proportional Band Width
• Failsafe mode for communication loss
• Every room unit can be bound with several relay boxes (e.g. to control several electric heating panels)
• CM61RF can be used with Automatic Time Setting module (Q6667B1007)

Special Features		Description				Setting
Adaptive Intelligent Recovery TM		The CM61RF will adjust the start time at upward setpoint changes so the desired temperature is reached at the programmed time e.g. 7:00 temperature 21oC.The chronotherm will monitor the start-up period and use this information to modify the start time calculation for the next upward setpoint change. The system will restrict the start time to a max of 3 hours before the programmed comfort time AIR does not function in cooling mode.				0* – disabled 1 – enabled

Pump exercise		When enabled the Pump Exercise will switch the relay on for 1 minute at 12:00 a.m. if the relay has not been switched on since 12:00 the previous day.				0* – disabled 1 – enabled
Upper Temperature Limit		The normal upper temperature limit of 30 oC can be reduced to 21 oC to save energy. Useful for small commercial premises.				21-30oC Factory setting 30oC*
Lower Temperature Limit		The normal lower temperature limit of 5 oC can be increased up to 16 oC to protect the inhabitants from cold. Useful for nursing homes.				5-16oC Factory setting 5oC*
Temperature Offset		If the Chronotherm is located in a hot/cold location and cannot be moved then the measured/ displayed temperature can be adjusted by +/- 3 oC.				-3 – +3oC Factory setting 0oC*
Proportional Band Width (PB)		The PB can be adjusted up to 3 oC (default is 1.5 oC) to provide better temperature control (less overshoot). Useful for: a.   Well insulated homes with over-sized heating systems b.   Air systems with fast response				1.5-3.0 K (adjustment step 0.1 K) Factory setting1.5 K*
Fail-safe mode		The CM61RF allows you to set the fail-safe mode of operation of the heating system when radio communication is lost. By default HC60 output relay will be switched OFF in case of communication loss. Alternatively you may choose to cycle the boiler at 2 min ON and 8min OFF. Useful when the building is not occupied for long periods of time and there is a high risk of frost damage.				0* – relay OFF 1 – relay cycles

DIMENSIONS

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.  It is recommended that the R6660C relay box is installed before commencing with the room unit installation (refer to appropriate Installation Guide).
