IMPORTANT! The Wireless Thermostat has ‘power stealing’ enabled by default, however, it is recommended to power the Thermostat with a common wire. If power stealing is required, verify that your HVAC system supports power stealing prior to installation in this mode. Changing this setting is described in Step 14, “Installation Instructions.” For more information about power stealing, see “Installing a Bypass Resister to Enable Power Stealing on a Wireless Thermostat” later in this document.
• • New construction, Control4 recommmends these options: • Install a common wire. • Use a Remote Temperature Sensor in the wall where the Thermostat is located. Run a wire to the furnace, and then install the Thermostat next to the furnace. Retrofits, the best solution is to install the Thermostat using an existing common wire. If the box does not have a common wire, you can: • Run a wire from the furnace to the Thermostat location. • Use Power Stealing (see Step 14 in “Installation Instructions”).
Zoned Systems Control4 supports zoned HVAC systems using a zoning panel. If used, however, a common wire needs to be installed at the Thermostat. Power stealing is not an option in this case. Remote Temperature Sensor A Remote Temperature Sensor allows the Thermostat to get its temperature readings from an area where the Thermostat is not physically located. Typically, the Thermostat will be located near the HVAC equipment with only the Remote Temperature Sensor on the wall in the living area.
Installation Instructions 1 2 3 4 Place the Wireless Thermostat in a proper location to ensure its efficiency and to avoid unnecessary cycling of the furnace or air conditioner. a. Place the Thermostat (or remote temperature sensor) away from direct sunlight, drafts, exterior doorways, skylights, windows, and exterior walls. b. Make sure the Thermostat gets strong ZigBee wireless reception: (1) Ensure that the Thermostat is within 150 feet of another Zigbee device.
5 Remove the Control4 Wireless Thermostat from the packaging, and detach the rear plate from the Thermostat. (Press the release clip at the bottom of the Thermostat to release it, and then swing the bottom of the Thermostat up.) 6 Thread the wires from the wall through the back of the large rectangu- Figure 3. Opening lar opening in the new rear plate (see Figure 3), and then position the new rear plate against the wall to make sure it sits flush.
14 Select the desired power supply method by enabling or disabling power stealing on the back of the Thermostat faceplate. • • Disable (recommended). Power stealing is disabled and the Thermostat requires the HVAC common wire connection for a dedicated power supply. Enable. The Thermostat steals a small amount of power from the HVAC system transformer to power itself. 15 On the back of the Thermostat faceplate, set the slide switches that sit next to the battery compartment to match your HVAC system: a.
16 Install the CR123A (3V) battery (included) in the Thermostat faceplate according to the polarity labels—POS (+) and NEG (-)—on the Thermostat’s circuit board. IMPORTANT! Do not install the battery with the wrong polarity. IMPORTANT! If the battery was already in place and you changed the slide switch settings, remove the battery and re-install it. This forces the Thermostat to reboot to the new configuration. 17 Attach the faceplate to the Thermostat’s rear plate: Figure 5. Faceplace Installation 1.
Composer Programming Instructions All advanced programming must be completed by a Control4 Dealer using Composer Pro. To see what advanced programming options are available as part of the Control4 system, follow these instructions. The Wireless Thermostat User Guide is available in the Documentation page at http: //www.control4.com/residential/products/resources/ which includes basic Thermostat programming instructions using a Touch Screen, On-Screen Navigator, or MyHome app.
Properties Fahrenheit or Celsius: Sets the temperature display in Fahrenheit or Celsius. View/Edit Schedule: Select to access and edit the Thermostat schedule. Vacation: Select to adjust the vacation heat and cool setpoints. Use Remote Temperature Sensor: If unchecked (default), the Thermostat will use the on-board local temperature sensor. Check this box to use an optional Remote Temperature Sensor. Buttons: Locks and unlocks the physical buttons on the Thermostat.
Time Format Date Format: Sets the format preferences for date (MM/DD/YYYY or DD/MM/YYYY). Time Format: Sets the format preferences for time (12h or 24h). Sync Time: Synchronizes the time displayed on the Thermostat with the Control4 Controller. Synchronization automatically occurs daily. Network Displays nformational boxes that provide ZigBee networking information (MAC and Firmware Version). Select Apply to… to apply the current properties to the selected Wireless Thermostats.
to 2 degrees, the heating system will engage until reaching 70 degrees Fahrenheit. Cooling Cutoff Point: Sets the temperature for the cooling system to turn off past the setpoint. To adjust, use the up and down arrows and press Set Cool Cutoff to confirm the change. Example: If the Cool Point is set to 68 degrees Fahrenheit, and the Cooling Cutoff Point is set to 2 degrees, the cooling system will engage until reaching 66 degrees Fahrenheit.
NOTE: For multistage systems, the deltas for the first and second stages are cumulative. If the first stage delta is set at 2 degrees, and the second stage delta is set at 2 degrees, the second stage will not engage until the current temperature has passed the stage setpoint by 4 degrees. However, the Auxiliary Heat and Emergency Heat deltas are NOT cumulative. Minimum Run Time (Minutes): Sets the minimum time the heating or cooling will run before shutting off. To adjust, use the up and down arrows.
NOTE: If set to the maximum time, the main heat pump stage and the auxiliary heat stage will run together indefinitely. Thermostat Relays This section shows the relays that are engaged during heating and cooling for the various Wireless Thermostat configurations.

Additional Information Traditionally, while in Heat Pump mode, relay ‘O’ will always call for COOL and relay ‘B’ will always call for Heat. Some HVAC systems, however, have O/B combined. Depending on the state of the reversing valve this can be changed so ‘B’ becomes COOL and ‘O’ becomes HEAT. Troubleshooting If the Thermostat is not working: 1. 2. 3. 4. Ensure that the HVAC system is not turned OFF. Check for proper wiring (see “Sample Wiring Configurations”).
Installing a Bypass Resistor to Enable Power Stealing on a Wireless Thermostat Although Control4 recommends using a common wire to provide power to the Thermostat, the Wireless Thermostat is capable of power stealing. This should only be done when using a common wire is not feasible. Not all HVAC configurations reliably permit power stealing.
Figure 6. Bypass Resistor 2 Access the 24V transformer and integrated control panel on the HVAC system. This typically requires removing the front panel of the furnace. Remember to turn OFF the power to the HVAC system before accessing the transformer. 3 Install the resistor on the HVAC system, not on the Thermostat. Wire the resistor from the Heat Relay Terminal (W or W1) to the common side of the 24Volt HVAC system transformer.
Figure 7.
4 Loosen the screw on the heat terminal (typically marked ‘W’ or ‘W1’) and secure one end of the resistor in the HVAC system’s Heat Relay Terminal by tightening the terminal screw. 5 Connect the other end of the resistor to the 24V common return path. Two completed wiring examples are shown below. Example 1. The first example (Figure 8) shows an HVAC system with a dedicated 24V Common screw terminal on the control board.
Example 2. This second example (Figure 9) shows a control board that does not provide a common wire screw terminal. In this example, an additional length of wire was added to the resistor which allowed it to connect from the ‘W’ terminal to the connector for the 24V common that connects from the HVAC transformer to the control board. Figure 9.
Sample Wiring Configurations The next several pages provide sample Thermostat connections and configurations for your reference. WARNING! Do not install LINE VOLTAGE wires to a LOW VOLTAGE wire. IMPORTANT! When utilizing power stealing, Control4 recommends installing the included 270 Ohm bypass resistor on the HVAC system to minimize any potential side effects. See the previous section “Installing a Bypass Resistor to Enable Power Stealing on a Wireless Thermostat.
