Fig. 56 — Completing Installation of Thru-the-Base Option
Check tightness of connector lock nuts before connecting elec-
trical conduits.
Field-supplied and field-installed liquid tight conduit connec-
tors and conduit may be attached to the connectors on the basepan.
Pull correctly rated high voltage and through appropriate conduits.
Connect the power conduit to the internal disconnect (if unit is so
equipped) or to the external disconnect (through unit side panel).
A hole must be field cut in the main control box bottom on the left
side so the 24-v control connections can be made. Connect the
control power conduit to the unit control box at this hole.
Units Without Thru-Base Connections
1. Install power wiring conduit through side panel openings.
Install conduit between disconnect and control box.
2. Install power lines to terminal connections as shown in
Fig. 38.
Field Control Wiring — The 580J*16 unit requires an external
temperature control device. This device can be a thermostat emu-
lation device provided as part of a third-party Building Manage-
ment System.
Thermostat — Install a Bryant-approved accessory 2 stage Cool-
ing/Heating thermostat according to installation instructions
included with the accessory. If using an electronic thermostat, con-
figure it for “non-heat pump” operation. Locate the thermostat
accessory on a solid wall in the conditioned space to sense average
temperature in accordance with the thermostat installation instruc-
tions.
If the thermostat contains a logic circuit requiring 24-v power,
use a thermostat cable or equivalent single leads of different colors
with minimum of seven leads. If the thermostat does not require a
24-v source (no “C” connection required), use a thermostat cable
or equivalent with minimum of six leads. Check the thermostat in-
stallation instructions for additional features which might require
additional conductors in the cable. For wire runs up to 50 ft. (15
m), use no. 18 AWG (American Wire Gage) insulated wire 95°F
(35°C minimum).
For 50 to 75 ft. (15 to 23 m), use no. 16 AWG insulated wire
95°F (35°C minimum). For over 75 ft. (23 m), use no. 14 AWG
insulated wire 95°F (35°C minimum). All wire sizes larger than
no. 18 AWG cannot be directly connected to the thermostat and
will require a junction box and splice at the thermostat.
Unit without Thru-Base Connection Kit — Pass the thermostat
control wires through the bushing on the unit end panel. Route the
wire through the snap-in wire tie and up to the web bushing near
the control box. Route the wire through the bushing and into the
bottom left side of the control box after removing one of the two
knockouts in the corner of the box. Use a connector at the control
box to protect the wire as it passes into the control box. Pull the
wires over to the terminal strip at the upper left corner of the Cen-
tral Terminal Board (CTB). Use the connector at the control box
and the wire tie to take up any slack in the thermostat wire to
ensure that it will not be damaged by contact with the condenser
Fig. 57 — Thermostat Wire Routing
NOTE: If thru-the-bottom connections accessory is used, refer to
the accessory installation instructions for information 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 heating,
when available.
PERFECT HUMIDITY™ CONTROL CONNECTIONS
Perfect Humidity – Space RH Controller
NOTE: Perfect Humidity is a factory installed option.
The Perfect Humidity dehumidification system requires a
field-supplied and installed space relative humidity control device.
This device may be a separate humidistat control (contact closes
on rise in space RH above control setpoint) or a combination ther-
mostat-humidistat control device with isolated contact set for de-
humidification control, see Fig. 58 and 59. The humidistat is nor-
mally used in applications where a temperature control is already
provided (such as a third-party Building Management System).
To Connect a Field-Supplied Humidistat for Sizes 08-14:
1. Route the humidistat 2-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. 54) to the 24-v barrier located on the left side of the
control box. The raceway provides the UL-required clear-
ance 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. 58.
To Connect a Field-Supplied Humidistat for Size 16:
1. Route the humidistat 2-conductor cable (field-supplied)
through the bushing the unit’s louvered end panel.
2. Route the cable through the snap-in wire tie and up to the
web bushing near the control box.
3. Feed the cable through the bushing and into the bottom left
side of the control box after removing one of the two knock-
outs in the corner of the box. Use a connector to protect the
cable as it enters the control box.
4. Use the connector and the wire tie to reduce any slack in the
humidistat cable to ensure that it will not be damaged by
contact with the condenser coil.
5. Use wire nuts to connect humidistat cable to two PINK leads
in the low-voltage wiring as shown in Fig. 59.
