Description

Function & Comments

Terminal Directional orientation: viewed with silkscreen labels upright

Limit, 24 VAC power and shutdown connections from unit wiring harness at left on upper edge of UCB

LIMIT

Monitored 24 VAC input through heat section limit
switch(es)

If voltage is absent, indicating the heat section is over-
temperature, the UCB will bring on the indoor blower

C

24 VAC, 75 VA transformer Common referenced
to cabinet ground

Connects through circuit traces to thermostat connection strip C
and indoor blower VFD pin C

24V

24 VAC, 75 VA transformer hot

Powers the UCB microprocessor, connects through circuit trace
to the SD 24 terminal

SD 24

24 VAC hot out for factory accessory smoke
detector, condensate overflow and/or user
shutdown relay switching in series

Connects through circuit trace to thermostat connection strip
SD-24. A wiring harness jumper plug connecting SD 24 to SD R
is in place if factory accessories for unit shutdown are not used -
this jumper plug must be removed if the switching of field-added
external accessories for unit shutdown are wired between
thermostat connection strip SD-24 and R

SD R

24 VAC hot return from factory accessory smoke
detector, condensate overflow and user shutdown
relay switching in series

Connects through circuit trace to the R terminal on the upper left
of the board
