• To avoid electrical shock and to prevent damage to the
furnace, air conditioner, and thermostat, disconnect the power
supply before installing or servicing the thermostat or any part
of the system. This can be done at the circuit breaker.
• Do not reconnect electricity until work is complete.
• Do not short (jumper) across electric terminals at the control
on the furnace or air conditioner to test the system. This can
damage the thermostat.
• Your thermostat is a precise instrument. Handle it with care.
• All wiring must conform to local codes and ordinances.
• This thermostat is designed for use with 4AA alkaline batteries
and/or 24-volt AC C wire (or a 12-24 AC or DC source) and
millivolt gas systems. Each thermostat relay load should be
limited to 1.0 amp; higher amperage can cause damage to the
thermostat.

Installation Location
To avoid having to move your wiring to a new location,
mount the CT100 in place of the old thermostat.
• Install the thermostat on an inside wall of an often-used room, about
5 ft. (1.5m) above the fl oor.
• Do not install where there are unusual heating conditions, such as:
in direct sunlight; near a lamp, radio, television, radiator register,
fi replace; near hot water pipes in the wall; or near a stove on the
other side of a wall.
• Do not locate in unusual cooling conditions, such as: on a wall
separating an unheated room; or in a draft from a stairwell, door, or
window.
• Do not locate in a damp area. This can lead to corrosion that will
shorten the thermostat’s life.
• Do not locate where air circulation is poor, such as: a corner, an
alcove, or behind an open door.
• Do not install the CT100 until all construction and painting is
complete.
• This thermostat does not require leveling.

1. Switch off electricity to the heating and cooling systems. This can
be done at the circuit breaker.
2. Remove the cover from the existing thermostat. Check for locking
screws on the side or front that must be loosened fi rst.
3. Attach provided labels to each wire for identifi cation. Refer to the
lettered terminal where the wires attach; do not use the color of
the wires.
4. Disconnect wires from the existing thermostat, and wind them
around a pencil to keep them from falling back inside the wall.
5. Loosen all mounting screws on the old thermostat and remove it
from the wall.

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

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.

Battery Installation
While the CT100 Thermostat can run without batteries on C-wire
power, you should install batteries as well to provide power to the
unit during outages.
1. Install four (4) AA alkaline batteries following the marked polarity
in the battery compartments. Insert the battery negative end fi rst
against the spring, then push the positive end in.
2. With all the wires connected and the unit attached to the wall, it
is time to turn the AC power back on. Reconnect the power at the
breaker you used to switch it off . The CT100 will power-up in the
OFF mode.
3. Trip the RESET button to implement the HVAC switch selections.
4. Your CT100 is not yet confi gured to operate your HVAC system.
You must now confi gure your thermostat (see page 15.)

Setup
Installation Guide CT100
• Always use new Alkaline batteries.
• Do not use rechargeable batteries of any type. They will no operate the
thermostat properly and may lead to damage.
• Do not mix old and new batteries.
• Do not mix battery types, for example Lithium with Alkaline.
• Do not dispose of batteries in fi re. Batteries may explode or leak.
• Always replace the batteries as soon as the “Low Batt” warning fl ashes. The
thermostat is a battery-powered device; you should replace the batteries
before they run out, as failure to replace batteries can result in excessive
heating or cooling of your house.
• Always replace the batteries once a year, even if the “Low Batt” indicator
does not fl ash. Replacing the batteries also helps to prevent leakage that
can corrode and damage the thermostat.
• If you are leaving your home for a month or more, you should replace the
batteries as a precaution against battery failure in your absence.
• Failing to replace the batteries when necessary could cause the thermo-
stat to lose power or malfunction. If the thermostat loses power, then the
thermostat will not control the temperature, which could result in your HVAC
system not functioning as you intended and lead to possible damage from
excessive heating or cooling.
• If the thermostat batteries fail with the heat OFF, this can result in NO HEAT
and possible frozen or broken pipes and water damage.
• If the thermostat batteries fail with the cool OFF, this can result in NO COOL
and could cause possible damage or excessive temperatures.
