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: If the *MVC950704CX 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 *MVC950704CX. This setting will keep
electrical consumption to a minimum. Set
the "Heat" speed DIP switches to "A".

In general lower heating speeds will: reduce electrical consump-
1780
tion, lower operating sound levels of the blower, and increase the
1620
outlet air temperature delivered to the home. The speeds avail-
1721
able allow the blower performance to be optimized for the par-
1822
ticular homeowner's needs.

The integrated control module provides a selectable heat off de-
1872
lay function. The heat off delay period may be set to 90, 120,
1922
150, 180 seconds using the DIP switches or jumper provided on
1230
the control module. The delay is factory shipped at 150 seconds

but may be changed to suit the installation requirements and/or
1470
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 compat-
ible 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 tradi-
tional (or non-communicating) system (see Electrical Connec-
tions for wiring connections).
A ComfortNet heating/air conditioning system differs from a non-
communicating/traditional system in the manner in which the
indoor unit, outdoor unit and thermostat interact with one an-
other. In a traditional system, the thermostat sends commands
to the indoor and outdoor units via analog 24 VAC signals. It is a
one-way communication path in that the indoor and outdoor units
typically do not return information to the thermostat.
