Table A

The standby power connections, L1 STBY and L2 STBY are meant to run

the indoor motor at a separate voltage from the other motors, compressor

and outdoor motor. When used as such, the jumpers, JH1 and JH2, must

be cut. This renders L1 & L2 and L1 STBY and L2 STBY isolated from

each other.

If there is no need to run the motors at a separate voltage the L1 = L1

STBY and L2 = L2 STBY. Therefore one voltage is used to run all motors.

If the jumpers are accidentally cut, then the connections can be

spliced to substitute for the missing jumpers.
