4. For replacement wires use conductors suitable for 105˚C.
5. For ampacities and overcurrent protection, see unit rating plate.
6. Connect to 24 vac/40va/class 2 circuit. See furnace/air handler
installation instructions for control circuit and optional
relay/transformer kits.
Defrost Board Operation:
1. Closing during defrost. Rating: 1 Amp.Max
2. Opens during defrost. Rating: 2HP at 230 Vac Max.

Provides “off” delay time of 5 min. when “Y” opens.
4. With DFT closed and “Y” closed, compressor run
time is accumulated. Opening of DFT during
defrost or interval period resets the interval to 0.
