English 3 Cleaning and care • • • • • • • • Use a soft, lint-free dry cloth for cleaning. Avoid getting moisture in openings. Do not use cleaning products or compressed air. Never use tools directly on the touchscreen. Never use paint on Wiser Air. Do not drop or crush Wiser Air, or allow Wiser Air to come into contact with liquids. Do not use a damaged device (such as one with a cracked screen). Functionality guarantees are no longer valid if the glass on the screen is broken.
English 4 Common system configurations In all applications: RC and C provide power to the thermostat; G controls the fan.
English 5 Wiring connections in detail RC, RH Wiser Air thermostats require 24VAC power from the Heating, Ventilating and Air Conditioning (HVAC) system in order to function. In most modern homes, a single HVAC unit provides both heating and cooling • In these cases, the RC/RH jumper shall be left in place. • 24V R wire may be landed on either the RH or RC terminal. If your home has 2 different sets of equipment for heating and cooling • The R wire from each HVAC unit must be wired separately.
English 6 C Wiser Air also requires a connection to the common side of the 24V transformer. If you are replacing a thermostat that also had a C wire • Move that wire to the C terminal. 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.
English 7 O/B By 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. U This is a universal terminal. It has a few different functions depending on configuration. In 3-stage heat systems • The U terminal is used to engage the third stage of heating. S1, S2 In advanced systems with exterior temperature measurement • S1 and S2 can be used to connect an exterior temperature sensor.
English 8 Installing Wiser Air 1. Disconnect power to the HVAC system by turning off the breaker. 2. Remove the existing thermostat’s panel from the wall without disconnecting the wiring. Figure 1 : Removal of existing thermostat and photograph of wiring.

English 9 TIP: Before proceeding further determine if you require the optional trim plate. 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.
English 10 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). Figure 3 : Front to back plate mounting. 12. Remove the protective plastic cover from the LCD touchscreen. 13.
English 11 Wiring terminals This section describes the procedure for connecting the wiring to the back plate. (Fig. 4) shows the Wiser Air backplate configuration. 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.
English 12 Troubleshooting If you experience difficulties with your Wiser Air thermostat setup, proceed as follows: • • • Disconnect power. Check that the front plate of Wiser Air is properly connected to the back plate. Check that the wires connected to the terminals on the back plate are properly attached. Contact the Customer Care Center 1-855-559-4737.
English Touchscreen Display 13 Installation wizard When installing Wiser Air for the first time, an installation wizard will launch to guide you through the initial configuration and registration of the device as soon as the device is connected. You will also be prompted to create an account on the Wiser Air website or in the mobile app. Follow the instructions shown. For more information, visit: www.wiserair.com/support.

Appendix Wiser Wire Extender Kit English 15 Do I need to use the wire extender? If there is no common wire (C) on your existing thermostat (see illustration below), and there is no spare wire available, the wire extender is needed or a new wire may be installed from the equipment to Wiser Air. Typical battery powered thermostat without common (C) terminal. The wire extender kit contains a diode pair and a Printed Circuit Board (PCB) assembly. To open the board, pinch and pull (Fig. 7).
English 16 Installation DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH Disconnect all power before working on equipment. Failure to follow these instructions will result in death or serious injury. TIP: Take a photograph of the initial wiring of the HVAC system to use as a reference and to help prevent wiring mishaps during the installation process. 3. 4. Disconnect the wires from the Y and W terminals on the thermostat. Connect the diode pair to the Y and W terminals (Fig. 8).
17 English Installing the wire extender kit in a 4-wire system 1. Isolate power from the HVAC system. WISER AIR BACK PLATE 2. Familiarize yourself with the HVAC control board located inside the air handler system. 3. Relocate the wire from the R terminal on the HVAC control board to the RC or RH terminal on the STAT side of the PCB assembly. Ensure that the jumper between the RC and RH terminals is installed.
