should not be mounted above other sensors that generate
heat during operation (such as relative humidity sensors).
The indoor temperature sensor should be between four
and six feet from the floor.
3.5.2.2 Mounting
Mount the sensor using the screws provided as shown
in Figure 3-21.
3.5.3 Outside Temperature Sen-
sor
3.5.3.1 Location
The outside or ambient temperature sensor should be
located on the north side of the building, preferably under
an eave to prevent sun-heated air from affecting the tem-
perature of the sensor.
3.5.3.2 Mounting
The temperature sensor may be mounted using any
standard tubing clamp. Retail Solutions also offers an alu-
minum cover and clamp (P/N 303-1111) which may be
mounted as shown in Figure 3-22 (fasteners are not pro-
vided).
3.5.4 Insertion Temperature Probe
3.5.4.1 Location
The 12-inch insertion temperature probe may be used
to monitor temperature in either the supply or return air
ducts of the AHU or RTU.
3.5.4.2 Mounting
The insertion probe may be mounted in any orientation
within the duct as long as the probe is in the air flow of the
duct. The probe housing should be secured using self-tap-
ping screws. A 0.250” diameter hole is required for the
probe. Figure 3-23 shows the installation of the insertion
probe (self-tapping screws are not provided).
3.5.5 Supply and Return Air Sen-
sors
In addition to the 12-inch insertion temperature probe,
Retail Solutions uses the same temperature sensor used for
