Thermistor Malfunction Error/Fault Indicators
The diagrams below illustrating what a customer may see on the display if there is a thermistor fault, such as a short
circuit or open circuit condition (See Figures 2-24, 2-25, 2-26). A thermistor fault will cause power to the compres-
sor and fans to be cut, and appropriate error codes will be logged. If the temperature alarm feature has been
enabled by pressing the ALARM key on the control panel, the ALARM icon will also flash, and the audible alarm will
beep.
NOTE:
