What is the Honeywell CM707?
The Honeywell CM707 is a programmable room thermostat designed to control heating systems by allowing users to set specific temperatures and heating times throughout the day.
The CM707 is a wired thermostat, rather than a wireless model. It was designed for domestic heating systems and provides programmable temperature control with a clear digital display.
Is the Honeywell CM707 wireless?
No. The Honeywell CM707 is a hard-wired programmable thermostat.
It is easy to confuse the CM707 with the Honeywell CM727 because the two thermostats have a very similar appearance. However, the CM727 is a wireless model, while the CM707 is wired.
If you're replacing an existing thermostat, it's important to check whether your installation requires a wired or wireless model before ordering a replacement.
Is the Honeywell CM707 still available?
The Honeywell CM707 has been discontinued.
If you're looking for a replacement for the CM707, the Honeywell T3H110A0066 is the replacement model available from Plumbco.

How do I switch on the heating using a Honeywell CM707?
The CM707 can operate automatically according to its programmed heating schedule. Pressing the AUTO button activates the programmed schedule.
If you want to temporarily increase or decrease the temperature, use the up and down buttons to adjust the set temperature.
How do I manually change the temperature on a Honeywell CM707?
Use the up and down buttons on the thermostat to adjust the desired temperature.
The temperature you select will remain in place until the programmed settings take over again or you make another adjustment.
Why is my Honeywell CM707 display blank?
If the CM707 display is blank, check the thermostat's batteries first, as depleted batteries can cause the display to stop working.
If replacing the batteries doesn't resolve the issue, there may be a problem with the thermostat, wiring or power supply to the heating system. If you're unsure, it's best to have the installation checked by a suitably qualified heating professional.
