“ENTERING WATER TEMP SENSOR FAIL”

Actions to

be Initiated

A “Disable Water Side Economizer” request is issued to “Water Side Economizer Temperature Enable Function”

Reset

An automatic reset occurs after the Entering Water Temp. input returns to within range continuously for 10 seconds.

Evaporator Temperature Sensor Failure—Circuit 1, 2, 3, or 4

Problem

The evaporator temperature sensor (ckt #1, 2, 3, or 4) is out of range.

Check

Sensor resistance should be between 830 ohms (200°F) and 345.7Kohms (-40°F). If so, check field/unit wiring between sensor
and MCM/SCM.

Reason for
Diagnostic

The unit is reading a signal that is out of range for the circuit #1 evaporator temperature sensor input (temp < -55°F or temp >
209°F).

Controls

Reaction

The coil frost protection function for the refrigeration circuit (#1, 2, 3, or 4) only is disabled.

Reset

Required

(PAR) An automatic reset occurs after the #1, 2, 3, or 4 evaporator temp input returns to its allowable range for 10 seconds.
