If you are replacing a thermostat that did not have a C wire• If there are spare conductors that were not connected to your old thermostat, one of these can possibly be used as the C conductor. Before connecting the spare wire to C on the thermostat, verify that that the conductor is connected to the 24VAC Transformer common terminal in the HVAC wiring compartment. Connect the conductor at the HVAC equipment if necessary and then connect it to the C terminal on the thermostat.• If no spare conductors are available, then use the Wire Extender as described in the Appendix.6
EnglishWiser Air Installation Guide 1-855-559-4737 www.wiserair.comInstallation ProcedureMERCURY HAZARD If replacing an existing thermostat that uses a sealed tube of mercury, do not dispose of the tube in the trash. Contact local waste management authorities for information on the safe disposal or recycling of the mercury. Failure to safely dispose of the mercury can result in exposure leading to serious health damage.Optional trim plate mounting If you are replacing an existing thermostat, you have the option of using the provided Wiser Air trim plate. If the hole left by the removal of the existing unit is larger than the back plate of the Wiser Air thermostat, use the optional trim plate. Run the wires and anchor the mounting screws through it while attaching the back plate to the wall (Fig. 2). Make sure to attach the trim plate with the central hole oriented upward.WARNINGO/BBy default, the thermostat operates per Orange Wire Mode. It can be changed to Blue Wire Mode in the settings.In a heat pump system• The O/B terminal engages the reversing valve.UThis is a universal terminal. It has a few different functions depending on conguration.In 3-stage heat systems• The U terminal is used to engage the third stage of heating.S1, S2In advanced systems with exterior temperature measurement• S1 and S2 can be used to connect an exterior temperature sensor.• Use Schneider Electric part number EER57200 or another 10K based thermistor.7

TIP: Before proceeding further check if you require a wire extender (see Appendix).4. Disconnect the wiring of the existing thermostat and remove the back plate. TIP: Acceptable wire gauge for use with Wiser Air is solid 18 to 22 AWG (0.33 to 0.82mm²). 5. Pull the wires 6in (15cm) out of the wall if they are not already pulled out.6. Insert the wires through the central hole in the Wiser Air back plate.7. If required, strip each wire 0.25in (0.6cm) from the end (does not apply to replacing pre-existing units).8. Gently push the wiring back into the hole. TIP: See the Wiring terminals section (p.11) in this guide before proceeding further.Figure 2 : Wiring connection and back plate attachment (optional trim plate shown).9

Connect the wiring to the Wiser Air back plate, matching the terminal connections to those in the photograph of the existing thermostat’s wiring or according to the wiring requirements of your HVAC system. See wiring instructions on page 11.10. Attach the Wiser Air back plate to the wall using the provided screws in the mounting holes in the top and bottom (Fig. 2).11. Attach the front of Wiser Air to the back plate, making sure that the front is oriented correctly so that the terminal pins on the front panel match the pins on the back plate. Do not use excessive force on the Wiser Air as this can damage the terminal pins (Fig. 3).12. Remove the protective plastic cover from the LCD touchscreen. 13. Reconnect power to the HVAC system.10

When replacing an older thermostat, refer to the photograph of the original wiring taken in Step 3 of the installation procedure to connect the wiring to the correct terminals. See the caution below.For a new installation, consult the documentation for your HVAC system to determine the correct wiring terminal connections. Match the wiring labels to the terminal labels. For more information or assistance in determining the correct wiring for your HVAC system, see the HVAC wiring help sections on the Wiser Air website (www.wiserair.com/support).Figure 4 : Wiring terminals and jumper.11Failure to remove this jumper, when wires are connected to both RC and RH, can cause damage to your Wiser Air.EQUIPMENT OPERATION HAZARD• You must remove the backplate jumper if your old system had separate wires connected to RC and RH.• Never use any tools on screwless terminals of Wiser Air.Save the backplate jumper for future use.NOTICE TIP: To ensure that Wiser Air is wired correctly. Place the thermostat in either heating or cooling mode. Set the set point 2 degrees above or below the current temperature. Conrm that your system engages in either heating or cooling. For heat pumps, an additional step is required to check auxiliary heating. Set the set point 5 degrees below the current set point. The air should feel noticeably warmer than the 2 degree check.
