Connect Sensors After Brazing
1. Identify the T1, T2, T2A and T2B sensors in the
accessory packet. See Figure 17.
2. Secure the T2 sensor to the air handler unit’s coil at
the middle of the coil. See Figure 18.
3. Secure the T2A sensor to the air handler unit’s coil at
the coldest part of the coil. See Figure 18.
4. Insulate the T2A sensor.
5. Secure the T2B sensor to the air handler unit’s coil at
the outlet of the coil as close as possible to the coil.
See Figure 18.
6. Insulate the T2B sensor.
7. Secure the T1 sensor at the air handler unit return
air inlet or inside of the zone being served by the air
handler. See Figure 18.

NOTE -
Coil Sensors should be installed
after brazing has been completed.
NOTE -
Typical coil examples shown. Refer
to the coil manufacture’s literature for spe-
cific coil or AHU installation/positioning.
