Wiring the AC Transformer
1321 Transformer
Connect the 1321 Transformer to terminals 1 and 2 on the control board. See Wire Run Chart below
for wire size to use. Use 1321CN in Canada.
1361X10 Transformer (required if using Powerline Carrier devices)
1. Splice one end of a 3-conductor cable to the wire ends of the SA4120XM-1 Cable.
2. Connect the SA4120XM-1 cable plug to the 8-pin connector on the control (see the Summary of
Connections diagram for location of the 8-pin connector).
3. Connect the other end of the 3-conductor cable to the 1361X10 Transformer, as shown.
Canada: See Powerline Carrier Device section for connections to the PSC04 X-10 Interface and
trigger pins.
Notes
• Use caution when wiring the transformer to the control to guard against blowing the transformer
fuse (the fuse is non-replaceable).
• Wiring to the AC transformer must not exceed 250 feet using 16 gauge wire. The voltage level
between terminals 1 and 2 of the control must not fall below 16.5VAC or else an “AC LOSS”
message will be displayed.
• Do not plug the transformer into the AC outlet while making any wiring connections to the control.
As a safety precaution, always power down the control when making such connections.
