sor

3.5.3.1Location

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.

3.5.3.2Mounting

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

3.5.4.1Location

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.

3.5.4.2Mounting

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 3-23shows the installation of the insertion probe (self-tapping screws are not provided).
