The High limit control is pre-set and does not need to be adjusted. If the furnace is overheating consult
your HVAC installer for proper duct installation, pressures and sizing.
The fan limit control heat settings are pre-set and do not need to be changed. If the room fan is cycling often
consult your HVAC contractor for proper duct pressure setting.
