CM700 Wireless

Installation Guide

CM727 / CM721 Wireless Programmable

Room Thermostat & BDR91 Relay box

Description

The Honeywell CM700 Wireless (CM727 or
CM721) is a modern wireless programmable
room thermostat based on Honeywell’s proven
programming philosophy. To further improve the
ease of use, this product includes a large LCD
display with backlighting to assist customers
during daily use.
The CM727/721 room thermostat communicates
with the BDR91 relay box on an 868MHz Radio
Frequency (RF) band to control a single heating
system component such as a boiler, pump or
zone valve. Neither product will communicate with
other RF products that use different frequencies or
communication protocols.
Note: The RF link between the individual room
thermostat (CM727/721) and relay box (BDR91)
in system packs provided by Honeywell is pre-
configured at the factory and therefore SHOULD
be installed at the same site. This makes the
installation process fast and easy, but if products
from individual system packs are separated, or
mixed with other pre-configured system packs
during installations please refer to section 5.1
Binding / Rebinding Procedure to bind the desired
units together and allow them to communicate with
each other.
