PF100
The Wall Control sends and receives it’s informa-
tion from the control board through a 4 wire Datacom
cable. There is a 100’ length of this cable supplied with
the furnace. 100’ lengths of this cable can also be or-
dered separately, part # 3-20-02583. Or any Datacom
cable -CAT 3 - 2 twisted pair 24ga solid wire can be
acquired at a local electrical supply house. Also any CAT
3- 24ga. solid wire 2, 3, or 4 pair cable can be used
because they all have the same pair color combinations.
The maximum length of wall control wiring is 200 feet.
The furnace connecting point is a 4 pole screw ter-
minal block on the side of the hopper just around the
corner to the right of the control. Follow the wiring
instructions on the label alongside the terminal block.
See Fig. 31.
CAUTION: With this small of wire gauge, care
must be taken not to overtighten the terminal screws,
thus breaking the wire.
There are tie-wrap holes in the face of the hopper
aprox. every 6” to keep the cable secure and out of the
way.
The Wall Control is made to fit on a standard wall
case electrical box. It could also be mounted directly to
a stud using 2 drywall screws. In either case the screws
should be turned in and tested for a snug fit when the
Wall Control is slid down over the screws. The Wall
Control only hangs on the screws so a good fit is impor-
tant.
Remove the Wall Control and make the Datacom
cable connections with the UY auto splicers provided.
DO NOT STRIP THE WIRES. Following the wiring
diagram on the inside of the Wall Control make each
splice. See Fig. 32. Insert the two matching color wires
fully into the two holes of one of the UY connectors. A
pair of standard Channel-lock pliers works ideally to
squeeze the raised button down into the UY connector
body. Extra UY connectors can be purchased.
Part # 3-20-00200
NOTE: A pair of needle nose pliers may be nec-
essary to insert the BLUE T-stat wires fully into the con-
nector. Visually inspect to see that the wires are fully
inserted before squeezing the UY splicer.
