TEMPERATURE MONITORING:
Problem 1
Can’t program temperature limits; or the unit won’t read the
temperature sensor.
Cause
The temperature sensor has been
disconnected or has broken wires.
Solution
Examine the wires to temperature
sensor and connect or replace wiring.
Problem 2
The temperature reading is -109° F or -87° F or -85°C or -66° C.
Cause
Temperature sensor wires are
touching or have shorted.
Solution
Verify and correct wiring.
Problem 3
Temperature reads 115° F or 168° F or 57° C or 76° C.
Cause
a) The zone is configured for the
wrong type of thermistor (i.e., 2.8k
vs. 10k)
b) Temperature sensing may be
affected by a source of ambient
heat (ie., direct sunlight, or heat
duct proximity).
Solution
Manually configure the zone as
described in Chapter 4.
Try moving the sensor to a different
location.
Problem 4
Temperature reading is inaccurate.
