Honeywell CM921,, i let my daughter stupidly play

Honeywell CM921,, i let my daughter stupidly play about the thermostat and now when i put it on manual (like I always have done) it doesn't go any higher than 5 degrees. I've looked through all books and on the Internet to find the answer to what she has done but can't find anything about it anywhere. Can you help? Thanks

It's either because the thermo sensor is faulty or the location is wrong. Try setting the temp one degree above room temp and see if that works, if it does it's a location issue. The thermo should be close to the centre of the house, not near an outlet or the RA vent & not in a breezeway or other heatsink, at approx 1.5m above floor level.

Honeywell CM921 Showing room temp at -24 degrees, How do I reset?


Heya this is a manufacturing fault from honeywell them selves when it comes up -24 basically it needs to be replaced there is no way around in if you get in touch with honeywell they are generally good about it also if you provide them with the date code and model code they will be greatfull as it seems they have sent out a "bad batch". you locate this by:

A) Move the slide in to the off position
B) Press and hold i for 5 seconds
C) Unit will enter settings mode
D) Press and hold the i button and the + and ¿ button together
E) The unit will hold the relay on for 5 minutes and you can view by pressing the down arrow twice for model id/date code (ww/yy)

I hope this helps
