Thermostat - Bryant 575J 16T Series Installation, Start-Up And Service Instructions Manual

THERMOSTAT

Install a Bryant-approved accessory thermostat according to
installation instructions included with the accessory. For com-
plete economizer function, select a two-stage cooling thermo-
stat. Locate the thermostat accessory on a solid wall in the con-
ditioned space to sense average temperature in accordance with
the thermostat installation instructions.
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 five leads. If the thermostat does not
require a 24-v source (no "C" connection required), use a ther-
mostat cable or equivalent with minimum of four leads. Check
the thermostat installation 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 Gauge) insulated wire (35°C minimum). For 50 to 75 ft
(15 to 23 m), use no. 16 AWG insulated wire (35°C minimum).
For over 75 ft (23 m), use no. 14 AWG insulated wire (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.
