Built -In Sensor Configuration; Adding A Hc60Ng Zone Valve Controller; Resetting A Bound Hr80Uk - Honeywell YZ667A1060 Installation Manual

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.
