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).

5. Recommended Fan size.

Duct and Fan are field supply. A fan capable of generating 15 CFM at a

static pressure of approximately .26 inches W.C.

Wiring

•Recommended wire size- 14 AWG.

10A Fuse

(Field Supply)

• Install the current sensor around one of the compressor line voltage

wires.

• Tuck sensor into the clearance behind the compressor wire molex

plug.

• Secure the current sensor with a zip tie.

Current Sensor Installation

• 4 zip ties are needed for correct installation.

• Secure the current sensor wires with all four zip ties according to the

arrows. Do not tie around any of the copper lines.

•Cut the ends of the zip ties.
