Honeywell CM921

Hello, my Honeywell CM921 Thermostat does not display properly, I can hardly see anything on the LCD screen.

Can I buy another same thermostat and bind it with my current receiver, or do I have to change both of them?

Thanks

Have you tried new batteries?

It is possible to rebind a new thermostat to your existing reciever. The rebinding procedure will be in the manual.

But i am not aware of anywhere that you can buy just the thermostat. They always come in a package of thermostat and reciever. Maybe have a look on ebay and see what you can find

Thanks for help.

Yes, there are people selling the thermostat seperately on Ebay. Just want to make sure it works with my existing receiver.

You can buy the thermostat as a spare, but it will be easier just to buy the set.

Another question, are the receivers for CM921 same as CM927? juste wondering if I can bind the CM927 thermostat or CM92E thermostat to my current receiver?

Yes. I am pretty sure they are the same. But i would give honeywell a ring to double check this beforehand!

They are the same.

There seems to be a batch of these thermostats with faulty screens.

Email Honeywell and tell them your problem. Some people have had them replaced for nothing.

The CM927 LCD screen problem seems to be as bad if not worse

When i spoke to honeywell about the display issue they told me they will repair the screen for 5 years, i sent a few back and they never asked to see proof of purchase, there customer service is great give them a ring.

Thanks for all your help above.

I have contacted Honeywell last week. They agreed to send me a replacement for free even it is 4 years old, and ask me to send the old one back. Just got the new thermostat yesterday, and bind it to the old receiver very easily.

So problem solved, and 120 pounds saved. Just hope this one will last longer.

There might be fault with the product, but I am really impressed with Honeywell's customer service.
