3. Not suitable on systems that exceed 150 volts to ground.
4. For replacement wires use conductors suitable for 105°C
5. For supply wire ampacities and overcurrent protection, see unit data label.
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)Closes during defrost.
Rating: 1 Amp. Max.
2)Opens during defrost.
Rating: 2 HP. at 230 Vac Max.
3)Closed when “Y” is on. Open
when “Y” is off. Provides “off”
delay time of 5 mins. 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.
5)Ground on location provided inside compressor
terminal box.
