7. Select the heating speed for your model from the heating
speed chart in the Specification Sheet. The adjust setting
(already established by the cooling speed selection)
determines which set of speeds are available. The selected
speed must provide a temperature rise within the rise range
listed with the particular model.

Example:
The *MVC80704BX is set for 990 CFM on
cooling, the “ADJUST” is set to “+” (plus). The
four heating speeds available are “A Plus”, “B
Plus”, “C Plus”, and “D Plus”. “A Plus” has a rise
of 38°°°°°F for both stages which is within the
20-50°F rise range for the *MVC80704BX . This
setting will keep electrical consumption to a
minimum. Set the “Heat” speed DIP switches
to “A”.

8. Select the desired “heating” speed tap by positioning
switches 7 and 8 appropriately. Refer to figure above. Verify
CFM by noting the number displayed on the dual 7-segment
LED display.
In general lower heating speeds will: reduce electrical consump-
tion, lower operating sound levels of the blower, and increase the
outlet air temperature delivered to the home. The speeds available
allow the blower performance to be optimized for the particular
homeowner’s needs.

The integrated control module provides a selectable heat off delay
function. The heat off delay period may be set to 90, 120, 150, 180
seconds using the DIP switches or jumper provided on the control
module. The delay is factory shipped at 150 seconds but may be
changed to suit the installation requirements and/or homeowner
preference. Refer to the following figures for switch positions and
corresponding delay times.
