Prepare Wires
Make sure your wires are labeled. If necessary, fi nd the “other
end” connection for each wire on your heating or air conditioning
equipment and note the label there.
1. Fan out wires so that they are aligned with their terminals.
2. Position wires behind the CT100 and over the terminal area.
3. Do not bunch wires behind the CT100. Feed any slack back into
the wall opening.

Follow these guidelines for safe and secure wire connections:
• Use at least 2.6 in. of wire for each of your connections to the
CT100.
• If you do not have enough wire, splice additional wire to allow
enough slack.
• Terminals accept wires from 16-22 awg.
• Remove 1/8 in. insulation from the tip of each wire.
• Take care not to damage the labels for each wire.
!
CAUTION
Do not allow wires to touch
each other or other parts on
the thermostat.
If you have both RH and
RC connections you must
remove the jumper wire
between these two terminals.

Connecting Your Wires
Reference the Detailed Wire Diagram on page 18 to identify your
wiring diagram and set-up information. If necessary, contact
customer support for help.
1. Connect a labeled wire only to a matching lettered terminal.
2. Insert the wire in the terminal well and tighten the screw securely.
The CT100 can be externally powered with a power source
rated from 12V to 24V, AC or DC, at 300ma or greater. If
used, connect to the C and RH terminals (no polarity).
The 24VAC “C” wire is the other side of the 24VAC heating
transformer and can be found where the other thermostat
wires connect at the wall or at the furnace. Do not use the
common or ground side of the line voltage.
The CT100 runs on 4 AA alkaline batteries, the C wire (if
available), or both batteries and the C-wire. If you do not
have a C wire, you can run a new wire from the HVAC or
use a standard 12-24V [AC or DC] wall transformer.
The C-wire is optional but preferred for all installations.
