1 GENERAL
The CM Zone Wireless Domestic Heating Zoning System
offers high levels of comfort and energy savings for the
home. It provides the ability to control two individual zones
at different comfort levels and at different times. A typical
example being the living areas and the bedrooms being
controlled separately.
The standard CM Zone Pack contains a Room Unit, a Relay
Module and six Radiator Controllers all pre-bound with three
Radiator Controllers bound to Zone 1 and three bound to
Zone 2. The System can be expanded or modified and the
methods used are described within this Guide.
To get the best from the installed system it is recommended
to use Honeywell VT15, VT117 or VT200 TRV bodies and a
Honeywell DU145 Automatic Bypass Valve.
For application support please contact your nearest
Honeywell salesman, for technical assistance please contact

The CM67z Room Unit provides a central point from which to configure the system and set
the time and temperature profiles for each Zone. At a given time, as defined within a Zone
profile, the CM67z Room Unit transmits the required temperature setpoint to the respective
HR80UK Radiator Controllers, local temperature control and override is then provided at
each HR80UK Radiator Controller.
In the default setting, the CM67z Room Unit on-board sensor is disabled.This may be ena-
bled for certain applications as described within Section 8: Changing the configuration
For normal operation refer to the CM Zone User Guide

Section 6: HR80UK Radiator Controller
Caution!
!When selecting the operating site of the HR80UK ensure that the dis-
tance to other wireless devices such as wireless headphones, cordless
phones etc. is at least 1-2m.
The HR80UK Radiator Controller provides local room temperature control based upon
setpoint information received from the CM67z Room Unit and sends Load Demand
signals based upon room conditions to the HC60NG Relay Module. Setpoints can be
temporarily overridden using the adjustment dial.
The HR80UK can be fitted onto Honeywell VT15, VT117, VT200 and many other manu-
facturers TRV bodies with a M30x1.5mm thread and a 12.9 - 10.5 mm valve closing point,
adaptors may be available for manufacturers with non standard connections. For more
information contact Honeywell Technical Help Desk, details on the back page.

8.3 Built -in sensor configuration
The CM67z Room Unit features a built-in temperature sensor
used for specific applications. Sensor operation is defined by
parameter 6:tS in Installer mode:
6:tS = 0 (Factory default. The built-in sensor is idle - not
used for control nor measurement).
6:tS = 1 (The built-in sensor is used only for measuring
the room temperature)
The symbol displayed next to the room temperature value indi-
cates that the sensor is used for measurement only and the
temperature in the room is controlled by the HR80UK Radiator
Controller. Due to different locations of the CM67z Room Unit
and HR80UK Radiator Controller
there may be a difference between
the setpoint displayed by the CM67z
Room Unit and the measured tem-
perature value.
6:tS =2 (The built-in sensor is used to
measure and control the room temper-
ature in zone 1 or when a zone valve
is used in zone 1) The CM67z Room
Unit must be located in zone 1.
To complete the configuration you must set the 17:SU param-
eter to decide which system components will use the tempera-
ture value from the CM67z Room Unit:
17:SU = 0 - HR80UK’s only (factory default)
17:SU = 1 - HC60NG (zone valve controller) only,
HR80UK’s will use their own built-in sensor.
17:SU = 2 - both HR80UK’s and HC60NG.

No binding data in the HR80UK.
HR80UK bound to the wrong zone.
Missing binding data in the HC60NG.
Bad position of the CM67z.
The HC60NG receives no messages:
RF signal is blocked (e.g due to bad posi-
tion of the CM67z) or CM67z and HR80UK
batteries are exhausted.
The HC60NG has not received signals
from one (or more) transmitters in the
system but still receives signals from other
transmitters: RF signal is blocked (e.g due
to bad position of the CM67z) or CM67z
and HR80UK batteries are exhausted.
