• Increase blower speed to reduce temperature rise.
• Decrease blower speed to increase temperature rise.
Change the blower heat taps as required to maintain proper temperature
rise for Heating and Cooling as described above. To change blower
motor speed selections for heating mode, remove blower motor lead
from control HEAT terminal. See Fig. 37. Select desired blower motor
speed lead from one of the other motor leads and relocate it/them to
HEAT (heating blower tap) terminal(s). Reconnect original lead on
SPARE terminal.
Adjust Blower Off Delay (Heat Mode)
If desired, the main blower off time delay period may be lengthened or
shortened when operating in the heating mode to provide greater
comfort. For position and location of jumpers on control center, see
Fig. 37 and Fig. 72.
Table 19 – Blower Off Delay Jumper Positions
The blower off delay has four adjustable settings from 90 sec to 180 sec.
See Table 19. The blower off delay jumpers are located on the furnace
control See Fig. 37 and Fig. 72. To change the blower off delay setting,
move the jumper from one set of pins on the control to the pins used for
the desired blower off delay. Factory blower off delay setting is 120 sec.
