Separable RC and RH connections are provided for systems with
separate transformers for heating and cooling. To accommodate
separate transformers, cut jumper R12 on the Equipment Control-
ler board. It is located just below and to the right of the RC and RH
connections. As shipped, the R12 jumper ties RC and RH
terminals together so either can be used in single transformer
application.
When installing a 24-vac humidifer, connect it directly to the
HUM terminal on Equipment Controller, and C terminal of indoor
equipment. Do not use an external humidstat. All necessary control
is provided by Zone Perfect Plus.
When using an FK series fan coil, connect DHUM (dehumidify)
output directly to DH terminal of fan coil. This output may also
drive a relay (connected with other side to C) which can be
connected to reduce fan speed in other types of blowers. The relay
will be energized when humidity is normal and will deenergize
when humidity is high, calling for reduced fan speed.
An LAT sensor must be connected in all systems. Both LAT and
HPT sensors must be connected in heat pump/fan coil systems.
WIRING CONSIDERATIONS
Zone Perfect Plus treats all furnaces as if they were 2-stage. For
single stage equipment, connect to W1. The same holds true for
auxiliary heat in fan coils. (Refer to Fig. 15-38.)
With any 2-stage furnace, configure the furnace so that low fire is
controlled by W1 and high fire is controlled by W1 and W2
together. This means the internal algorithm is to be disabled. See
furnace instructions.
Some variable speed furnaces have a "zoning" setting. If such a
setting exists, it should be turned on. It forces the furnace to adjust
its airflow more frequently to accommodate the effects of damper
movement. See furnace instructions.
All 2-speed air conditioners and heat pumps need to be configured
so that Y1 controls low speed and Y1 and Y2 together control high
speed in both heating and cooling. This is usually done by
selecting the "zoning" position of the stage 2 latch pot. See 2-speed
equipment instructions.
In 2-speed dual fuel applications (2-speed heat pump and furnace),
do not set the furnace interface jumper on the heat pump to ON,
