WIRING DIAGRAM
NOTES:
1. Disconnect all power before servicing.
2. For supply connections use copper conductors only.
3. For replacement wires use conductors suitable for 105deg. C
4. For supply wire ampacities and overcurrent protection, see unit data label.
5. Connect to 24 vac/40va/class 2 circuit. See furnace/air handler installation
instructions for control circuit and optional Relay/Transformer Kits.
1. Couper le courant avant de faire letretien.
2. Employez uniquement des conducteurs en cuivre

DEFROST BOARD OPERATION:
CLOSES DURING DEFROST.
RATING: 1 AMP. MAX.
OPENS DURING DEFROST.
RATING: 2 HP. AT 230 VAC MAX.
CLOSED WHEN “Y” IS ON.
OPEN WHEN “Y” IS OFF.
PROVIDES “OFF” DELAY TIME
OF 5 MIN. WHEN “Y” OPENS.
WITH DFT CLOSED AND “Y” CLOSED, COMPRESSOR RUN TIME IS
ACCUMULATED. OPENING OF DFT DURING DEFROST OR INTERVAL
PERIOD RESETS THE INTERVAL TO 0.
GROUND ON LOCATION PROVIDED INSIDE COMPRESSOR
TERMINAL BOX.
