Getting Started Radio Thermostat 3
Installation Guide CT102 Getting Started Tools Needed Small Phillips screwdriver Drill with 3/16-in.(4.8mm) bit ! CAUTION • 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.

Installation Guide CT102 Getting Started Installation Location To avoid having to move your wiring to a new location, mount the CT102 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 floor. • Do not install where there are unusual heating conditions, such as: in direct sunlight; near a lamp, radio, television, radiator register, fireplace; near hot water pipes in the wall; or near a stove on the other side of a wall.
Installation Guide CT102 Getting Started ! CAUTION • Read instructions carefully before removing any wiring from an existing thermostat. • Label all wires before disconnecting them form the existing thermostat. 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 first. 3. Attach provided labels to each wire for identification.
Installation Guide CT102 Wiring Prepare Wires Make sure your wires are labeled. If necessary, find 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 CT102 and over the terminal area. 3. Do not bunch wires behind the CT102. Feed any slack back into the wall opening.
Installation Guide CT102 Wiring Connecting Your Wires Reference the Wire Diagram on page # 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 CT102 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).
Installation Guide CT102 Wiring Mount the CT102 to the Wall 1. Hold the CT102 against the wall, with the wires coming over the top; above terminal block. 2. Position CT102 for best appearance, cover the hole in the wall. 3. Mark first and drill a 3/16-in.(4.8mm) hole at each screw location. 4. If you are mounting the CT102 to sheet rock or if you are using the old mounting holes, use the plastic anchors provided. 5. Attach the CT102 to the wall with the screws provided.

Installation Guide CT102 Setup Selecting HVAC & Heat Types Both switches are located in the battery compartment. HVAC TYPE SWITCH 1. Set HVAC TYPE to the type of heating and cooling system. Norm Heat Pump All other systems Heat Pump system with or without Auxiliary Heat 2. Set the HEAT TYPE to the type of fuel used for heating. If HVAC Type is Heat Pump, then select fuel used for Auxiliary.
Installation Guide CT102 Setup Power Supply While the CT102 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 first 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.
Installation Guide CT102 Setup ! THERMOSTAT BATTERY CAUTIONS • 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 fire. Batteries may explode or leak. • Always replace the batteries as soon as the “Low Batt” warning flashes.
