Richard walks through how to wirelessly pair/bind a Honeywell CMS927B1049 Wireless Room Thermostat to a BDR91A1000 Wireless Relay Box. When these were purchased together in a pack, they were known as a Honeywell CM927.

The same pairing procedure works with both CM921 and CM927. The BDR91 Wireless Relay Box pairing procedure is exactly the same when using a R8810A1018 OpenTherm Bridge or HC60NG/R6660D Wireless Relay Box instead of a BDR91 Wireless Relay Box.

If you have a faulty Honeywell CM721, CM727, CM921 or CM927 room thermostat, you can purchase a Pro Wireless Programmable Thermostat from The Intergas Shop website to replace these models - [ Ссылка ]
