14. Reinstall sensor. See following sections:
• See Section 7.29.5 for STS and SRS Reinstallation
• See Section 7.29.6 for RRS and RTS Reinstallation
• See Section 7.29.7 for DTS Reinstallation
• See Section 7.29.8 for ETS1 and ETS2 Reinstallation
NOTE
The P5 Pre-Trip test must be run to deactivate probe alarms (see Section 5.8).
7.29.5 Supply Sensor (STS/SRS) Reinstallation
To properly reinstall a unit Supply Temperature Sensor (STS) or Supply Recorder Sensor (SRS), the sensor must be
fully inserted into the probe holder. This positioning will give the sensor the optimum amount of exposure to the
supply air stream, and will allow the controller to operate correctly. Insufficient probe insertion into the probe holder
will result in poor temperature control due to the lack of air flow over the sensor.
It is also necessary to ensure that the probe tip does not contact the back panel. The design minimum clearance of
6 mm (1/4 inch) should be maintained (see Figure 7.33).

7.29.6 Return Sensor (RRS/RTS) Reinstallation
To properly reinstall a Return Temperature Sensor (RTS) or Return Recorder Sensor (RRS), be sure to position the
enlarged positioning section of the sensor against the side of the mounting clamp (see Figure 7.34).
