Honeywell CM921

HELP ME!!

- I have just moved into a new house and we have an Ideal combi boiler and a CM921 honeywell wireless thermostat. _ I have no idea if this is working properly and the installation guide is not much help... I need to find a plumber in the Chingford area to check the system and give me a idiots guide to this system.

Thanks

The CM921 is really quite simple to work. Make sure all other controls for the heating elsewhere are set on continuous and use the CM921 for the program. All you need to do is make sure the times are set right. When you switch it onto manual you will hear the boiler fire when you ask for heat. You used to be able to download intructions from the Honeywell website.
