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?

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.

How do I set my own temperature program for each day of the week?
1. Move the slider to the PROGram position. You will see the first temperature change time and temperature level for Monday’s program (the two small arrows are displayed only when the programmed temperature level is shown). The flashing display indicates that you can make changes.
2. Press the + or – button to adjust the first temperature change time. Holding the button down will change the time quickly. The change time can be set in 10 minute steps from 03:00 in the morning. The change time can be adjusted to any time up to 02:50 on the next morning, so you can maintain the evening temperature after midnight. (Note: If you are pressing the + button and the display flashes the next change time number 2, it means the next change time 2 will be pushed forward if you continue to press the + button).
3. Press the TEMPerature or button to adjust the first temperature level. Holding the button down will change the temperature quickly. The temperature can be set in 0.5°C steps from 5°C to 30°C.
4. Press the PROGram 2 button to display the second temperature change time and temperature level for Monday. Set these by pressing the
+ or – button and TEMPerature or button.
5. The remaining temperature changes for Monday can be displayed by pressing PROGram buttons 3, 4, 5 and 6 and adjusted by using the
+ or – button and TEMPerature or button. (If you don’t want to use all the temperature change times 2, 3, 4, 5 or 6 refer to the next question “What if I don’t want to use all 6 temperature change times?”). You now have a choice to set the program for the next day:- 6a. Press the COPY DAY button to copy Monday’s program into Tuesday. To set several days of the week to the same program, press the COPY DAY button repeatedly. 6b. Press the DAY 1..7 button to step the day marker to Tuesday (Day 2). The program for Tuesday can then be set as described in steps 2 to 5. Programs for Wednesday (Day 3) to Sunday (Day 7) can be set in the same way, using the DAY 1..7 button. 7. Move the slider to the AUTOmatic position when you have completed steps 6a or 6b, The Chronotherm will now control the room temperature to match your program. What if I don’t want to use all 6 temperature change times?

The built-in program uses 6 temperature change times as indicated by the numbers 1, 2, 3, 4, 5 and 6 on the display. With the slider in the
PROGram position, unwanted change times can be deleted by holding the appropriate PROGram buttons (2, 3, 4, 5 or 6) down for a few seconds. The change time will be removed and the display will show dashes instead of a time / temperature display. Deleted temperature change times can be brought back by again pressing the appropriate program button (2, 3, 4, 5 or 6) for a few seconds, with the slider in the PROGram position.
Can I change the programmed temperature for a short time? When the slider is in the AUTOmatic position the temperature can be adjusted temporarily by pressing the TEMPerature or button. This temperature will return to the program at the next temperature change time. How do I check the programmed temperature? In normal operation the temperature displayed is the actual room temperature. To check the programmed temperature press the INFOrmaton button and the display will show the programmed temperature with the two small arrows. How do I set one temperature for the whole day? To operate as a simple thermostat with one temperature throughout the day, move the slider to the MANual position. Adjust the manual temperature by pressing the TEMPerature or button. The manual temperature can be set anywhere from 5°C to 30°C in 0.5°C steps.
