TESTING THE ELECTRONIC CONTROL

CHECKING ROOM TEMPERATURE

1.Check the room temperature at the electronic control pad by pressing at the same time, the Fan Speed button and the Temp/Hour button on the WS/WE/ WY models (see figures 5 and 6).

2.The indoor temperature will display for 10 seconds. Indoortemperaturecanbeviewedinallmodes,including the Test Mode. The display can be changed back to the SET temperature by pressing any key (except the Power (on/off button) or it can do so automatically after 10 seconds have elapsed.

ACTIVATING TEST MODE

Activate Test Mode by pressing at the same time, the Mode button and the Temp/Hour button on on the WS/WE/ WY models (see figures 5 and 6).

The LEDs for Set/Hour: “Start Time” and “Stop Time” will blink 1 bps while Test Mode is active.

Test Mode has a duration of 90 minutes. Test Mode can be activated under any function, including Off.

Test Mode is cancelled by pressing the Power (on/off) button, unplugging the unit, or when the 90 minutes times out.

Test Mode settings are factory default of:

Unit operation On, MoneySaver On, Cool Mode, 60 degrees F, speed fan on High. “Timer” and “Set Hour” features are non-functional.

Test Mode overrides the three minute compressor Lock- out, all delays for fan motor start, speed change, and when switching modes.

ERROR CODE MODE

Error Code Mode is used to display all error codes stored since reset. It is a sub-mode of Test Mode. Unit must be in Test Mode to enter the Error Code function.

Activating Error Code Mode: Press the TIMER On/ Off” button on the WS/WE/WY models (see figures 5 and 6). The LED for the TIMER On/Off will flash 1 bps (beats per second) while Error Code Mode is active.

Pressing the Temp/Hour button will display “00”. Consecutive presses will scroll through all error codes

stored. Press the Temp/Hour button to see the reverse order of the error codes. When the end of the stored error codes is reached the temperature Set Point will appear. (Each error code is listed once)

Exiting Error Code Mode: press the Timer On/Off button.

Clearing Error Codes: Error codes are cleared from the memory by exiting from Error Code Mode.

MEMORY: On WS/WE/WY

The electronic control has a memory to retain all functions and settings, as set up by the user, in the event of a power failure. For example: once power is restored to the unit, there is a two second delay before the fan comes on and approximately three minutes delay before the compressor is activated providing that the mode was set for cooling and the set point temperature has not been met in the room.
