2 CT102INSTALLATION GUIDE Getting Started 3 Radio Thermostat 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. 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. 4 Getting StartedInstallation Guide CT102 Interior View RESET WIRE TERMINALS CB OW W2Y Y2RHRC G A AUX 1 2 TOUCH SCREEN STATUS INDICATOR BATTERIES HVAC SELECTION SWITCHES BATTERIES COVER 5 Getting StartedInstallation Guide CT102 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. 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 thermostats life. Do not locate where air circulation is poor, such as: a corner, an alcove, or behind an open door. Do not install the CT102 until all construction and painting is complete. This thermostat does not require leveling. 6 Getting StartedInstallation Guide CT102! 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. 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. 4 W W W G C G G C 7 Getting StartedInstallation Guide CT102 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. JUMPER WIRE FROM HVAC SYSTEM Y Y2RHRC G A G 2.6 C W Y H R If you have both RH and RC connections you must remove the jumper wire between these two terminals.

! CAUTION Do not allow wires to touch each other or other parts on the thermostat. Follow these guidelines for safe and secure wire connections:

Use at least 2.6 in. of wire for each of your connections to the CT102. 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. 8 WiringInstallation Guide CT102 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). 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 CT102 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. From HVAC System RH G C CBO WW2 W Y YY2RHRCG A 9 WiringInstallation Guide CT102 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.

4 PROPERLY INSTALLED AA ALKALINE BATTERIES 13 SetupInstallation Guide CT102! 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. 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 flash. 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. 14 SetupInstallation Guide CT102 HVAC Setup HVAC selection switches must be set first (see page X), then make sure the CT102 is powered up and the mode is set to Off.

When the CT102 has successfully joined a Z-Wave network, the RADIO 11 RADIO 11 MATE icon is replaced by the LINK icon under the radio tower. Similarly, when you are trying to disconnect from (leave) a network, the LINK icon disappears when the node has successfully left the network. 4. Your controller indicates that the thermostat was successfully added to its network (see your specific controllers User Manual for details.) 7 Product Overview Z-Wave Power Sources Z-Wave and HVAC Setup Do not change the HVAC setup or HVAC selection switches if the thermostat is connected to a Z-Wave network. If you need to change the HVAC system:

1. Remove the thermostat from the Z-Wave network. 2. Change the HVAC Setup selection. See Install Guide page 18 for full instructions. 3. Connect the thermostat to the Z-Wave network. Z-Wave and Power Supply The thermostats node type is fixed when it connects to the Z-Wave network; if the C-Wire is not connected and is only battery-powered when connecting to the network, the thermostat will remain a frequent listening routing slave (FLiRS) node until it is removed from the network. When your thermostat is running on battery power, the Z-Wave radio will turn off to help conserve battery life. The CT102 Z-Wave radio module supports Z-Wave beaming, which allows other devices in the network to wake up the Z-Wave module and accept commands and then go back to sleep. When your thermostat is running on C-Wire power, the Z-Wave radio will stay on and actively help route messages within the Z-Wave network. The thermostats node type is fixed when it connects to the Z-Wave network; if the C-Wire is present and powered when connecting to the network, the thermostat will remain an always-

listening node until it is removed from the network. Z-Wave and Thermostat Program To get the most out of your new thermostat, it needs to be paired to a Z-Wave system. When you are paired to a Z-Wave system, the Z-Wave application on your device controls your thermostats programs. You can still temporarily override settings on the thermostat itself, but otherwise you can control it remotely. No Z-WAVE system?

See your specific Z-Wave controllers User Manual for detailed instructions on operating your thermostat through the network. Behavior Note: When power is first applied to this device it will broadcast a Hail message followed by a Node Information frame. This behavior is to maintain backwards compatibility with older controllers that work with this line of devices. Advanced Z-Wave Information The CT102 supports compliant mapping of the Z-Wave BASIC_ COMMAND_CLASS to the CT thermostat Energy Saving and Comfort Mode as follows:

Basic Set (Value = 0x00) = Set Energy Saving Mode Basic Set (Value = 0x01-0x63 & 0xFF) = Set Comfort Mode Energy Savings applies a 4 F setback to the existing set point temperature to comply with EPA recommendations for energy savings. 2 CT102 Thermostat Z Wave Anti-theft The Anti-Theft Command Class disables a subset of supported/

controlled command classes in the thermostat if the thermostat is being disconnected from and reconnected to a Z-Wave network.

(This thermostat supports version 2 of the Anti-Theft Command Class.) This command class is typically used when installing a thermostat in a public location, such as a hotel room or conference center. The command class allows the user to lock the thermostat to the actual Z-Wave network and to render it useless if it is removed from the local network without being unlocked. Another application would be to protect service-provider-owned products from leaving the service providers network before they are paid for.
