BASIC WIRING

115 VAC enters the unit through the wiring box, then goes to the network filter box. A three-wire harness connects the network filter box
to the power board's seven-pin connector.

Wires from the seven-pin connector go to the nine-pin connector for the blower power cord. The blower power cord connects to the
internal blower harness, or to the external blower wiring box. If a power cable is included with the external blower, it does not need to be
used. A triac on the power board controls the blower speed.

115 VAC enters the electronic transformer through the wire harness. The electronic transformer supplies 12 VDC to the LEDs through the
LED wire harness. A three-pin harness on the electronic transformer's secondary side sends 12 VDC back to the power board. It is then
routed to the touch control through the wire harness.
