PG 2REMOVE OLD UNIT Switch OFF electricity to the HEATING and COOLING systems. Then follow these steps:• Remove cover from old thermostat. Most are snap-on types and simply pull off. Some have locking screws on the side or front. These must be loosened. DO NOT remove wires. Note the letters printed near the terminals. Attach labels (enclosed) to each wire for identication. Caution Read instructions carefully before removing any wiring from existing thermostat. Wires must be labeled before they are removed. THERE IS NO STANDARD COLOR CODE. When remov-ing wires from their terminals, ignore the color of the wires and LABEL THEM by the lettered terminal where they were screwed.• Label the wires one at a time. You must label all the wires before you proceed. • With all wires labeled, remove them from the old unit.• Make sure the wires do not fall back inside the wall. You can wind them around a pencil to keep them from falling.• Loosen all screws on the old thermostat and remove it from the wall.TOOLS You will need a small Phillips screwdriver and a drill with 3/16-in. (4.8mm) bit for wall mounts. LOCATION Replacement installations - mount the CT110 in place of the old thermostat. A new location will require moving your wiring.For new installations and relocating the CT110 - follow the guidelines listed below: • Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the oor, and in a room that is used often.• Do not install it where there are unusual heating conditions, such as: in direct sunlight; near a lamp, radio, television, radiator register, replace; near hot water pipes in a 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 thermostat life. • Do not locate where air circulation is poor, such as: in a corner, an alcove; behind an open door. • Do not install the CT110 until all construction and painting has been completed.• This thermostat does not require leveling.Good5ft.(1.5m)

PG 4What wires do you have? Make sure your wires are labeled. This may require you to nd the ‘other end’ connection for each wire on your heating or air conditioning equipment and read the label there. Refer to the Wire Reference page at end of install section for better understanding of wire labels from different HVAC system makers. IMPORTANT: The CT110 runs on 4 AA alkaline batteries and/or the C wire if available. 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. A constant power source is required when using a radio module. IMPORTANT: If you have both RH and RC you need to remove the jumper wire between these 2 terminals.Prepare Wires Please follow these guidelines for safe and secure wire connections:• You will need at least 2.6” of wire for each of your connections to the CT110. • If you do not have enough wire, splice additional wire to allow enough slack. • Terminals accept wires from 16-22awg.• Fan out wires below the hole as shown.• Remove insulation 1/8” from the tip of each wire.• When handling, take care not to damage the labels for each wire.Caution Do not allow wires to touch each other or parts on thermostat.
