8301-067 Outdoor Temperature Sensor
Troubleshooting
To verify sensor operation:
1. Remove lid from outdoor temperature/humidity
sensor.
2. Remove wire nuts from green and white wires (see
Figure 57 on page 43).
3. Use a temperature probe (preferred method) or
local weather data to find ambient temperature
conditions.

4. Using an ohmmeter or resistance mode on a
multimeter, measure resistance across white leads
leading to the temperature sensor (see Figure 59).
5. Cross reference readings with Table 14.
A. If readings are consistent with reference
temperature, check wiring or offset in PLC if
outdoor temp value on PLC does not match.
B. If readings do not match, replace sensor.
