Fig. 31 — Low-Voltage Connections
Unit Without Thru-Base Connection Kit — Pass the ther-
mostat control wires through the hole provided in the corner
post; then feed the wires through the raceway built into the
corner post to the control box. Pull the wires over to the ter-
minal strip on the upper-left corner of the Controls Connec-
tion Board. See Fig. 32.
NOTE: If thru-the-bottom connections accessory is used,
refer to the accessory installation instructions for informa-
tion on routing power and control wiring.

Heat Anticipator Settings — Set heat anticipator settings at
0.14 amp for the first stage and 0.14 amp for second-stage heat-
ing, when available.

Control Connections
Perfect Humidity – Space RH Controller
NOTE: Perfect Humidity is a factory installed option which
is available for 07 models only.
The Perfect Humidity dehumidification system requires a
field-supplied and installed space relative humidity control de-
vice. This device may be a separate humidistat control (contact
closes on rise in space RH above control setpoint) or a combi-
nation thermostat-humidistat control device such as Bryant’s
Edge
®
Pro Thermidistat with isolated contact set for dehumidi-
fication control.
To Connect the field-installed humidistat (See Fig. 33)
1. Route the humidistat 2-conductor cable (field-sup-
plied) through the hole provided in the unit corner
post.
2. Feed wires through the raceway built into the corner post
(see Fig. 32) to the 24-v barrier located on the left side of
the control box. The raceway provides the UL-required
clearance between high-voltage and low-voltage wiring.
3. Use wire nuts to connect humidistat cable to two PINK
leads in the low–voltage wiring as shown in Fig. 34.
To connect the Edge Programmable Thermidistat
(T6-PRH01-A):
(See Fig. 35)
1. Route the Edge Programmable Thermostat multi-
conductor cable (field-supplied) through the hole
provided in the unit corner post.
2. Feed wires through the raceway built into the corner post
(see Fig. 32) to the 24-v barrier located on the left side of
the control box. The raceway provides the UL-required
clearance between high-voltage and low-voltage wiring.
3. The Edge Programmable Thermostat has dry contacts at
terminals D1 and D2 for dehumidification operation (see
Fig. 35). The dry contacts must be wired between CTB
terminal R and the PINK lead to the LTLO switch with
field-supplied wire nuts. Refer to the installation instruc-
tions included with the Bryant Edge Programmable Ther-
midistat device for more information.
