Bryant FK and FV series variable--speed fan coils, all variable--speed furnaces,
and select single and multi--stage furnaces with the dehumidify c onnection have
dehumidify inputs which connect directly to Thermidistat Control dry contact.
Refer to the furnace literature for dehumidification options.
The FK and FV series fan coils have a terminal marked DH which should be
connected to the Thermidistat Control dry contact output. Jumper J1 on fan coil
MUST be removed. It is located behind the DH terminal. Additionally blower
delay tap on fan coil should be set to 0/0 (no On delay and no OFF delay) when
using cool to dehumidify . With this selection, the blower stops when G signal is
removed, preventing re--evaporation of water from the coil which would occur
during the normal 90 sec blower off delay. See fan coil installation instructions
for more information. (See Wiring Diagram Reference Chart and Fig. 2 through
20 in Wiring Diagram section at the back of this piece literature.)
The furnace dehumidify input acts differently depending on which style of
variable speed, select single--stage or multi--stage furnace control you have.
Vacation (programmable models only)
A vacation selection is available specifically for times where the home will not
be occupied for an extended period. Vacation mode has an automatic hold,
meaning that setpoints are not affected by the programmed schedule. Vacation
mode is active for a specified period of time. While in vacation mode, the system
provides temperature and humidity protection for the home in the selected mode,
but not comfort. When vacation mode is active, an arrow will be displayed
beside “VACATION” in the upper left corner of the display.
