Pull the low-voltage control leads from the heater module(s) -
VIO and BRN (two of each if two modules are installed; iden-
tify for Module #1) - to the 4-pole terminal board TB4 located
on the heater bulkhead to the left of Heater #1. Connect the
VIO lead from Heater #1 to terminal TB4-1. For 2-stage heat-
ing, connect the VIO lead from Heater #2 to terminal TB4-2.
For 1-stage heating with 2 heater modules connect the VIO
lead from both Heater #1 and #2 to terminal TB4-1. Connect
both BRN leads to terminal TB4-3. See Fig. 79.

50TC 16 UNIT ELECTRIC HEATERS
50TC-D16 units may be equipped with field-installed accesso-
ry electric heaters. The heaters are modular in design. One or
two heater modules may be used in a unit.
Heater modules are installed in the compartment below the in-
door (supply) fan outlet. Access is through the indoor access
panel (see Fig. 82). Heater modules slide into the compartment
on tracks along the bottom of the heater opening. See Fig. 81.
Single Point Boxes
When heaters are installed, power wiring to both heaters and
the rest of the unit is connected via the single point box acces-
sory, which will be installed directly under the unit control box,
just to the left of the partition separating the indoor section
(with electric heaters) from the outdoor section. The single
point box has a hinged access cover. See Fig. 83. The single
point box also includes tap conductors to complete the wiring
between the single point box and the unit’s main control box
terminals. Refer to the accessory heater and single point box
installation instructions for details on tap connections.
