(Control Products HOS-001A Board)
The application switch located between relay X3 & X4 must be set to match the original
board application. Place this switch in the ALP position if there is no white wire supplied to
the K1 connector. If there is a white wire, place the switch in the C position. If this switch is
placed in the wrong position, either the compressor contactor will remain energized with the
control switch OFF, or the unit will not start.
The dip switches should be adjusted per the adjustment chart published in the Tech Specs
book. Number 8 must remain in the OFF position.
