NOTES
1 Use copper conductors only.
2 When using the central remote control, see manual for connection to the unit.
3 When installing the electric heater, change the wiring for the heater circuit. The main powersupply has to be supplied independently.
4 For high or low E.S.P. operation, change the wiring connection of X4A as shown on the wiring diagram.
5 When connecting the input wires from outside, forced off or on/off operation can be selected by remote controller. See installation manual for
more details.
