Fault LED flash code of 13
The fault LED (Figure 36) will be flashing in groups of
13 flashes. This indicates that the outdoor External
Ambient Temperature Sensor is reading out of range.
Read the DC voltage at the External Ambient Tem-
perature Sensor EXT. ODT terminal boards (TB1) with
the sensor connected or remove the sensor leads and
read the resistance of the sensor (Figure 46).
Yes: Turn off the 24 volts A/C to the Charge As-
sist™ Control and then re-power the control. If the
13 flash codes continue to be displayed, replace
the Charge Assist™ Control. Note: Disconnect the
External Ambient Temperature Sensor and re-power
the control system. The Charge Assist™ Control
will now use the internal Ambient Sensor.
No: When the DC voltage and temperature do not
agree with the external temperature, resistance tem-
perature, resistance and voltage chart, replace the
External Ambient Temperature Sensor.
Do the External Ambient Temperature and the DC volt-
age read at the External Ambient Temperature Sensor
(TB) or resistance of the sensor agree with the exter-
nal temperature, resistance and voltage chart? (See
Reference Materials)

Fault LED flash code of 14
Error code of ERR 114 will be reported to the Comfort
Control. This indicates that the Personality Module
plugged into the Charge Assist™ Control is unplugged
or its stored information is not usable.
Is the Personality Module (Figure 47) plugged into the
Charge Assist™ Control?
Yes: Turn off the 24 volt A/C supply to the Charge
Assist™ Control and then re-power. Fault code
should clear itself; if the fault code does not clear
itself, replace the Personality Module. Note: To
order a Personality Module you must have the com-
plete model and serial number from the unit it goes
into.
No: Turn off the 24 volt AC supply and the plug the
Personality Module back into its socket #J12. Re-
power the Charge Assist™ Control, the fault code
should clear itself.
