1.Activate Error Code Mode by pressing the “TIMER ON/OFF” button on XQ & WS models. LED for the “TIMER ON/OFF” will flash 1bps while Error Code Mode is active. Pressing the “TEMP/HR + ” button will display 00. Consecutive presses will scroll through all error codes logged. Press the “TEMP/HR - ” button to see the reverse order of all error codes logged. When the end of logged error codes is reached the temperature set point will appear.

E2 KEYBOARD STUCK ERROR: If key button(s) are pressed continuously for twenty seconds or more. If MODE key is stuck, unit will default to cool. Exit Error Code Mode to see if error “E2” is no longer displayed and unit is functioning. Replace board if “E2” still displays after exiting Error Code Mode.

E3 FROST PROBE OPEN: Normal operation is allowed. Ohm frost probe. Replace probe if ohm value not read. If ohm value present replace board.

E4 FROST PROBE SHORT: Normal operation allowed. Replace probe.

E5 INDOOR PROBE OPEN: Control assumes indoor ambient temperature is 90 degree F and unit will operate. Ohm indoor probe. Replace probe if ohm value not read.

E6 INDOOR PROBE SHORT: Control assumes ambient temperature is 90 degree F and unit will operate. Replace probe.

NOTE: All Error Code displays for Frost & Indoor Probe will allow unit to operate. Unit may or will ice up if faulty components not replaced.
