J-Discharge Air Temperature Sensor (DATS)
Units may have a discharge air temperature sensor locat-
ed in the supply duct or in the coil. Two type sensors are
used. FIGURE 52 (located in the coil) and FIGURE 54
(located in the plenum). If the sensor is suspect, check
the location using TABLE 35 and FIGURE 53 (type 1) or
TABLE 36 and FIGURE 55 (type 2). See FIGURE 56 for
field wiring to the furnace control. If the location and wiring
are correct, but the sensor is not working properly, replace
the sensor. Follow the DATS instructions found in the kit
for replacing the sensor. The location is not compatible
between sensor types.
