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.

Activating HC60NG Relay Module binding procedure
Press and hold the push button of the HC60NG Relay Module
for 5 sec to enter the binding mode. The red LED will flash at
0.5 sec on/0.5 sec off.
Activate the binding procedure at the CM67z Room Unit as
described in section 8.2 for zone 1. When binding information
is received correctly the red LED of the zone valve controller
will be switched off.
NOTE:
Install in accordance with local wiring regulations
CAUTION:
Observe ambient temperature and current limits (see HC60NG wiring label)
a. Thermal actuator b. Zone valve c. Zone valve
8.4 Adding a HC60NG Zone valve controller
The HC60NG relay module can also be configured for control-
ling a zone valve. This is restricted to zone 1 only.
Before the binding procedure is started the following CM67z
Room Unit parameters need to be set in order to control the
zone 1 temperatures via the HC60NG as zone valve controller:
Enter the installer mode of the CM67z Room Unit and set the
installer parameters: 6:tS =1, 9:Sn =1, 17:SU =1 or 2 (see
Built-in sensor configuration).
