Which wires do you have?
Determine which step-by-step wiring diagram you •
should use from the next pages. Make sure your
wires are labeled. This may require you to find the
‘other end’ connection for each wire on your heat-
ing or air conditioning equipment and read the label
there.
You must have a wire marked “C” (24VAC) for the •
CA8900 to operate. Without the 24VAC power, the
CA8900 will run on its back-up batteries for just a
few days.

screw location, and then
mount the base.
Thread wires through the hole in the thermostat 6.

Leave wires loose in the opening, take care that 7.
