What is a Chronotherm?
A Honeywell Chronotherm is a programmable thermostat that controls
your heating system, so that you can have comfortable temperatures
when you are at home and energy savings when you are out. These
instructions explain how to program and operate your Chronotherm to
get the most comfort at the least cost.
What will the CM67 Chronotherm do for me?
Attractive slim styling makes it ideal for location in any room in
your home
7 day program lets you set the CM67 to match your weekly
6 daily independent temperature levels let you set any 6
temperatures from 5 to 30°C at any time each day, to match your
daily lifestyle
Party button lets you temporarily maintain (or adjust) the current
temperature for 1 - 23 hours. Useful when you have friends round
or go out of the house for a short while
Day Off button copies Sunday’s program into tomorrow so that
you can make the CM67 follow the Sunday program if you have a
day off during the week
Holiday button saves energy by letting you reduce the tempera-
ture for 1 to 99 days while you are on holiday, returning to normal
operation on the day you return
Memory holds the user program indefinitely so that it is never lost
even if you take the batteries out
Outside Temperature Sensor (optional accessory) can be fitted
to the CM67 to display the outside temperature
Telephone Interface (optional accessory) can be fitted to the
CM67 to allow remote setting of the temperature by telephone
Remote Temperature Sensor (optional accessory) can be fitted
to the CM67 to control the temperature from another room
How do I install the batteries?
1. Lift up the front flap to reveal the battery compartment. Open the
battery compartment by inserting a coin underneath the bottom
right edge of the flap and lift it out.
2. Pull the paper tab out to activate the 2 AA LR6 Alkaline Batteries
included and push the battery compartment firmly back into the
front of the unit. After a pause the unit will now display information.


3 Remote Temperature Sensor Accessory
The Remote Temperature Sensor accessory can be fitted to your
Chronotherm to control the temperature of another room where it is
inconvenient to locate the Chronotherm e.g. commercial premises
where the public may adjust buttons.
4. Telephone Interface Accessory
The Telephone Interface accessory can be fitted between your
Chronotherm and telephone to allow remote temperature setting by
telephone. When activated by making a phone call to your home and
keying a special code, the Telephone Interface will set the
Chronotherm temperature to 21°C and show the symbol. Normal
operation of the Chronotherm will be resumed by RESETTING the
output at the Telephone Interface Accessory or by re-dialling and
keying in the code for normal operation. The remote temperature
setting by telephone only works when the setting slider is in the
AUTOmatic, MANual or OFF positions.
Can I use my Chronotherm to control my air-
conditioning system?
Yes. Please refer to your installer for more information.
