75 ft (15 m 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 re-
quire a junction box and splice at the thermostat.

Connections
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. Using a connector at the control box to pro-
tect 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 coil. See Fig. 39.
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.
