NOTES:
1. If any of the original equipment wire is replaced use wire rated for 105°C.
2. Inducer (IDM) and blower (BLWM) motors contain internal auto-reset thermal overload switches (OL).
3. Blower motor speed selections are for average conditions, see installation instructions for details on
optimum speed selection.
4. Use only copper wire between the disconnect switch and the furnace junction box (JB).
5. This wire must be connected to furnace sheetmetal for control to detect flame.
6. Replace only with a 3 amp fuse.
7. Yellow lead not on all motors.
8. Blower-on delay, gas heating 45 seconds, cooling or heat pump 2 seconds.
9. Blower-off delay, gas heating 90, 135, 180 or 225 seconds, cooling or heat pump 90 seconds.
(135 seconds only on some models)
10. Ignition-lockout will occur after four consecutive unsuccessful trials-for-ignition. Control will auto-reset
after three hours.
11. When used, auxiliary limit switch (ALS) is on some downflow models only. When used, FL is on
upflow models only.
12. Some models may have spade quick connect terminals.
13. Factory connected when LGPS is not used.
14. Factory connected when BVSS is not used. BVSS used when Chimney Adapter Accessory Kit is
installed.
15. Gas valve leads are interchangeable on single stage valves.
