SAFETY : PLEASE SWITCH OFF MAINS TO THE AC BEFORE CONNECTING.

HOW TO CONNECT THE DIRECT CONNECTION METHOD:

Airtron Has two pairs of wires-The. Red and Green Pair and the Black pair.

• The red and green pair is used to power the Airtron on, and may be connected to the secondary terminal, inside the air conditioner or even from the PCB directly.
• The black pair is connected To the. Phase wire From the PCB To the relay Of the Compressor motor. Cut the phase wire From the PCB of the air conditioner leading to the compressor motor relay ( which is attached to the PCB of the AC),and the two black wires in your hand are connected to the two sides of the cut Phase wire.
• THE Phase Wire will light up with an electrical Tester for easy identification.

BOTH pairs Of wires from the Airtron are Potential-free.

IMPORTANT : PROCEED WITH THE THE WIRE CHECK TEST TO CONFIRM YOUR WIRING IS CORRECT AND then set your desired room temperature and enjoy the savings! (see the manual for the methodology).

IN NON INVERTERS PLEASE BE SURE TO REDUCE SET POINT ON YOUR AC TO IT’S LOWEST, AND SET YOUR DESIRED SET POINT ON THE AIRTRON.
