Status Code Recall Mode
Active status codes are stored in memory even when power is
absent. The most recently flashing status code (highest priority
active) can be recalled from memory via status code recall mode
and displayed using the amber LED. The status code recall mode is
accessed by shorting (use a clip wire) the “force defrost” connector
(labeled J2 on the board) and then power ON the unit. Please make
sure the unit is turned OFF before shorting the pins. Status call
recall mode will continue as long as the “force defrost” terminals
remain shorted. The unit will not attempt to heat or cool while the
terminals remain shorted. Once the status code is read, power down
the unit and remove the short.
