even though its instructions say to do so. The necessary interlock-
ing to keep both the heat pump and furnace from operating at the
same time is done by Zone Perfect Plus.

The special 3-stage auxiliary heat feature of Bryant thermostats is
incorporated into Zone Perfect Plus. This requires an FK type fan
coil and specific heater packages with a single-speed heat pump.
See FK fan coil Installation Instructions.

IX.

UNDERSTANDING SEQUENCE OF OPERATION

A.

Temperature Set Points

The Zone Perfect Plus System uses 2 temperature set points for
each zone, the higher for cooling and the lower for heating. A
minimum difference of 2°F is enforced between the 2 set points.
Each set point may be manually adjusted or controlled by a
programmed time schedule established by the home or business
owner.

B.

Heating and Cooling Comfort Set Points

If space temperature is between heating and cooling set points for
the zone, then the zone is said to be "satisfied" with respect to
temperatures. When a zone is satisfied, no heating or cooling is
required. When all zones are satisfied, there is no demand and the

equipment is turned off. For example, if cooling set point is 76°F
and heating set point is 72°F, then a space temperature of 73°F is
assumed to be satisfactory and no heating or cooling of the zone is
required.

If space temperature in a zone falls below heating set point, then
that zone needs to have heat added to zone which will raise space
temperature back to heating set point. For example, if heating set
point is 72°F and space temperature is 70°F, then space tempera-
ture must be raised 2°F in order for zone to be satisfied. In this
case, temperature "heating demand" for zone is 2°F. (72° minus
70°F.)

Otherwise, if space temperature in a zone rises above cooling set
point, then that zone needs to have heat removed from zone which
will lower space temperature back to cooling set point. For
example, if cooling set point is 76°F and space temperature is
77°F, space temperature must be lowered 1°F in order for zone to
be satisfied. In this case, "cooling demand" for zone is 1°F. (77°
minus 76°F.)

C.

Out Feature

A new feature called OUT can be selected via the OUT button.
When this selection is made, the system is being told that the
