PROBLEM
Fresh Air Intake w/ Compressor Operation Only
SOLUTION
Duct Fan Control
MODEL :18/24/36/42RLX Systems
1. Outline
The circuit shown below provides a cost effective solution for wiring a current switch
that monitors the compressor operation ON/OFF status and energizes the coil of a
relay which in turn close the contacts and provide line voltage to the duct fan. The
duct fan is required to introduce fresh (outside) air for ventilation.
2. Application
A third party current sensor switch with a built-in relay was
used in this application. The current sensor may be
installed around one of the compressor line voltage wires (Red,
Black or White).
