1. If any of the original equipment wire is replaced use wire rated for 105°C.
2. Use only copper wire between the disconnect switch and the
furnace junction box (JB).
3. This wire must be connected to furnace sheet metal for control
to prove lame.
4. Symbols are electrical representation only.
5. Solid lines inside PCB are printed circuit board conductors and
are Rot included in legend.
6. Replace only with a 3 amp fuse.
7. Inductor is used with 3/4 hp and 1 hp ECM Blower motors.
8. Factory connected when (LGPS) not used.
9. Blower off-delay, gas heating selections are (90, 120, 150, 180)
seconds, cooling or heat pump 90 seconds or 5 seconds when
dehumidify call is active.
10. Ignition lockout will occur after four consecutive usuccessful
trials for ignition. Control will auto-reset after three hours.
11. Inducer motor (IDM) contains internal auto-reset thermal overload switch.
12. Any of the 5 wires shown within the NEUTRAL L2 box can be
connected to any terminal within the box.
13. Blower motor (BLWM) is locked rotor overload protected by redundant
electronic control circuits.
