TESTING THE ELECTRONIC CONTROL

2003 XQ BOARDS & QME BOARDS Checking Room Temperature:

1.Check the room temperature at the electronic control pad by pressing the "FAN SPEED" button and the temperature "UP" button at the same time on XQ models.

2.Check the room temperature at the electronic control pad by pressing at the same time the "FAN SPEED" button and the "WARMER" button on QME models.

The indoor temperature will display for 10 seconds. Indoor temperature can be viewed in all modes, including the TEST mode. The display can be changed back to SET temperature by pressing any key, except the ON/OFF button, or after 10 seconds has elapsed.

Activating Test Mode: Activate test mode by pressing at the same time the "MODE" button and the temperature "DOWN" button on XQ models. LEDs for Hour, Start, and Stop will blink 1 bps while Test Mode is active.

Activate test mode by pressing at the same time the "MONEY SAVER" button and the "FILTER ALERT" button on QME models. LED for the Filter Alert will blink 1 bps while Test Mode is active.

Test Mode has duration of 90 minutes. Test Mode can be activated under any conditions, including Off. Test Mode is cancelled by pressing the On/Off button, unplugging the unit, or when the 90 minutes is timed out. All settings revert to the factory default settings of Cool, 75 degrees F, Timer and Set Hour features are nonfunctional.

Test Mode overrides the three-minute lockout, all delays for compressor and fan motor start / speed change, and no delay when switching modes.

Test Mode default settings are ON, Money Saver, 60 degrees F, and High fan speed.

Activating Error Code Mode: (Submode of Test Mode) Unit has to be in Test Mode to enter Error Code Mode

1.Activate Error Code Mode by pressing the "TIMER ON/ OFF" button on XQ models. LED for the "TIMER ON/OFF" will flash 1 bps 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.

Activate Error Code Mode by pressing at the same time the "A/C START" button and the "ON/OFF" button on QME models. LED for the "TIMER ON/OFF" will flash 1 bps while Error Code Mode is active. Pressing the "WARMER" button will display 00. Consecutive presses will scroll through all error codes logged. Press the "COOLER" 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.

IMPORTANT: Error Codes are cleared from the log by exiting from Error Code Mode. To exit on XQ mod- els, press Timer On/Off button. To exit QME models, press A/C Start and On/Off buttons. Or unplug unit to exit Error Code Mode. Plug unit in after 5 seconds to resume normal operation of unit.

TESTING THE ELECTRONIC CONTROL

ERROR CODE LISTINGS

E1 SHORT CYCLE SITUATION: Defined as (compressor powered on before the three minute time delay ten times in one hour. Investigate and correct short cycling problem.

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.

FROST PROBE SENSOR: disables compressor at 35 degrees F.

INDOOR PROBE SENSOR: Control range is 60 degrees F to 90 degrees F +/- 2 degrees F.

Indoor temperature will be displayed by pressing:
