WIRING DIAGRAM
NOTES:
1. Disconnect all power before servicing.
2. For supply connections use copper conductors only.
3. Not suitable on systems that exceed 150 volts to ground
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:
Closing during defrost.Rating: 1 Amp.Max.
Opens during defrost.Rating: 2HP at 230 Vac Max.
With DFT closed and “Y” closed, compressor run
time is accumulated. Opening of DFT during
defrost or interval period resets the interval to 0.
CC - Contactor Coil
CCH - Crankcase Heater
DFT - Defrost Thermostat
HPS - High Pressure Switch
RVS - Reversing Valve Solenoid
* - Hard Start Kit Field Installed
ODT - Outdoor Thermostat
1. Couper le courant avant de faire letretien.
2. Employez uniquement des conducteurs en cuivre.
3. Ne convient pas aux installations de plus de 150 volt a la terre.
