Pro Series Wireless Programmable Thermostat – Replaces Honeywell CMS927 & CMS921 Wireless Programmable Room Thermostats

Box Contains:

1x Pro Series 7 Day Programmable Wireless Room Unit
2x AA Alkaline Batteries
1x Wall Mount
1x Stand Mount
1x Binding Instructions

The Pro Series Wireless Programmable Thermostat is a BRAND NEW 2021 launched, 7 day programmable room thermostat designed to replace all existing Honeywell CM Series Wireless Thermostats.

The ‘Pro Series’ is made in the UK by Resideo (who were formally part of Honeywell International Inc.) and distributed to independent merchants via a national merchant wholesaler. Resideo (Honeywell Home) is the same manufacturer who made the CM700 & CM900 Series Thermostats.

If you take a good look at the Pro Series Wireless Programmable Thermostat, you will see it is nearly identical to Honeywell Home’s T3 Series Thermostat (the user display menu is identical). However, the big difference is that the Pro Series Wireless Programmable Thermostat will bind directly to any existing Honeywell Wireless Relay Boxes, where the T3 Series won’t, so you don’t have the hassle of having to get an installer out to fit this.

The Pro Series Wireless Programmable Thermostat will replace the following Honeywell CM Series products:

CM921, CMS921, CMS921B1042
CM927, CMS927, CMS927B1049
CM727, CMS727, CMS727E1016
CM721, CMS721

The Pro Series Wireless Programmable Thermostat works with the following Honeywell Wireless Relay Boxes:

R8810A OpenTherm Bridge



Binding Instructions Included
