Custom Cord Switching Procedure; Flap Control - Mitsubishi Heavy Industries SRK20ZD-S1 Technical Manual

(4) Custom cord switching procedure

If two wireless remote controllers are installed in one room, in order to prevent wrong operation due
to mixed signals, please modify the printed circuit board in the indoor unit's control box and the
remote controller using the following procedure. Be sure to modify both boards. If only one board is
modified, receiving (and operation) cannot be done.
(a) Modifying the indoor unit's printed circuit board
Take out the printed circuit board from the control box and cut off jumper wire (J6) using wire cutters.
After cutting of the jumper wire, take measures to prevent contact with the other the lead wires, etc.
(b) Modifying the wireless remote controller
(i) Remove the battery.
(ii) Cut the jumper wire shown in the figure at right.

(ii) When not operating
The flap returns to the position of air flow directly below, when operation has stopped.
(b) Memory flap
While the flap is operating if the AIRFLOW button is pushed once, it stops swinging at an angle.
As this angle is memorized in the microcomputer, the flap will be automatically set to the angle when next operation is started.
