FIELD CONTROL WIRING
The 48FE unit requires an external temperature control device.
This device can be a thermostat (field-supplied) or a SystemVu™
controller (available as factory-installed option for use on a Carrier
Comfort Network
®
or as a stand-alone control).
THERMOSTAT
Install a Carrier-approved accessory 2-stage thermostat according
to installation instructions included with the accessory. Locate the
thermostat accessory on a solid wall in the conditioned space to
sense average temperature in accordance with the thermostat in-
stallation 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 7 leads. If the thermostat does not require a 24 v
source (no “C” connection required), use a thermostat cable or
equivalent with minimum of 6 leads. Check the thermostat instal-
lation instructions for additional features which might require ad-
ditional 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 connect-
ed to the thermostat and will require a junction box and splice at
the thermostat.
UNITS WITHOUT THRU-BASE CONNECTIONS
Correctly rated low voltage wire can be routed through the rubber
grommet located on the corner post adjacent to the control box ac-
cess panel. Route wire through the grommet and then route the
wire behind the corner post utilizing the factory provided wire ties
secured to the control box. This will ensure separation of the field
low voltage wire and the high voltage circuit. Route the low volt-
age wire to the unit control board. See Fig. 52 and 53.
NOTE: If utilizing the thru-the-base connections, route the low
voltage wire through the wire ties to the unit control board.
HEAT ANTICIPATOR SETTINGS
Set heat anticipator settings at 0.14 amp for the first stage and
0.14 amp for second-stage heating.
TRANSFORMER CONNECTION FOR 208 V POWER
SUPPLY
All units except 208/230 v units are factory wired for the voltage
shown on the nameplate. If the 208/230 v unit is to be connected to
a 208 v power supply, the control transformer must be rewired by
moving the black wire with the 1/4 in. female spade connector
from the 230 v connection and moving it to the 208 v 1/4 in. male
terminal on the primary side of the transformer. Refer to unit label
diagram for additional information.

CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may cause a short circuit.
Carefully check the connection of control conductor for indoor
fan control at terminal G. Connecting the indoor fan lead to ter-
minal C will cause a short circuit condition, which can cause
component damage inside the unit or at the thermostat.
