GENERAL FURNACE OPERATION
After installation of the furnace is complete, it is ready for operation. The Honeywell Limit Control, in conjunction
with a wall thermostat, operates the distribution blower and the actuated draft on the front of the furnace. The
limit control is located on the rear of the furnace in the upper right corner and is accessible by removing the two
screws in the cover plate. DO NOT operate your furnace with this plate removed! The control can be adjusted to
your desired blower On/Off times. The factory settings are 100/150/200. The wall thermostat setting operates the
ON time of the actuated draft. If the temperature is below the setting on the wall thermostat, the actuated draft
will come open. (Recommended setting at 5 to 10 degrees higher than other heating thermostats.) The rst two
set points on the limit control operates the distribution blower. When the furnace plenum reaches the second
set point on the limit control, the distribution blower will come on. If the temperature falls to the rst set point, the
distribution blower will shut-off. The distribution blower is a three speed blower and can be manually adjusted by
means of the three position switch located behind the sliding access panel on the cold air return box. When the
furnace reaches the third set point on the limit control, the actuated damper will close, reducing the air setting
down to the minimum setting. The the actuated draft will open back up if the temperature falls below the setting
on the wall thermostat.
