case and, remove the upper case. (2 places) (Printed circuit board is attached to the upper part of
the remote controller.) (Refer to Fig. 38)
(2) Turn the main/sub changeover switch on one of the two remote controller printed circuit boards to
“S”. (Leave the switch of the other remote controller set to “M”.) (Refer to Fig. 39)
Wiring Method
(3) Remove the control box lid (Refer to “9. HOW TO CONNECT WIRINGS AND WIRING EXAMPLE”.)
