In general lower heating speeds will: reduce electrical
consumption, 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.
Continuous fan speeds that provide 25, 50, 75 and 100% of
the furnace’s maximum airflow capability are selectable via
dip switches S5- 3, 4.
Example:
If the furnace’s maximum airflow capability is
2000 CFM and 25% continuous fan speed
is selected, the continuous fan speed will
be 0.25 x 2000 CFM = 500 CFM.

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.

The ComfortNet system is a system that includes a
ComfortNet compatible furnace and air conditioner or heat
pump with a CTK0* thermostat. A valid ComfortNet system
could also be a compatible furnace, CTK0* thermostat and
non-compatible, single stage air conditioner. Any other
system configurations are considered invalid ComfortNet
systems and must be connected as a traditional (or non-
communicating) system (
see Electrical Connections
for wiring
connections).

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:
If the DM96VC0804CN** is set for 1210 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 46
°
F for both stages which
is within the 30-60°F rise range for the
DM96VC0804CN**. This setting will keep
electrical consumption to a minimum. Set
the “Heat” speed DIP switches to “A”.
