SPACE TEMPERATURE SENSOR INSTALLATION AND
WIRING — The space temperature (SPT) sensor accessory is
ordered separately for field installation. It is installed on
interior walls to measure room space air temperature. See
Fig. 16-20 and Table 6.
The wall plate accommodates both the NEMA (National
Electrical Manufacturing Association) standard and the Euro-
pean
1
/
4
DIN standard. The use of a junction box to accommo-
date the wiring is recommended for installation. The sensor
may be mounted directly on the wall, if acceptable by local
codes.
DO NOT mount the sensor in drafty areas such as near heat-
ing or air-conditioning ducts, open windows, fans, or over heat
sources such as baseboard heaters or radiators. Sensors mount-
ed in those areas will produce inaccurate readings.
Avoid corner locations. Allow at least 3 ft between the sen-
sor and any corner. Air in corners tends to be stagnant, resulting
in inaccurate sensor readings.
Sensor should be mounted approximately 5 ft up from the
floor, in an area that best represents the average temperature
found in the space (zone).
The space temperature sensor cover includes a service jack
connector. If wiring connection is made to the service jack, the
connector can then be used to connect a network service tool
with the Carrier Comfort Network® system.
Before installing the space temperature sensor, decide
whether or not the service jack wiring connection will be made.
If connection is desired, the CCN communication cable should
be available at time of sensor installation, for convenient
wiring connections. The cable selected must meet the
requirements for the entire network. See Connect the CCN
Communication Bus section for CCN communication cable
specifications.
