IMPORTANT: If your thermostat is built into the wall and connected to thick wires with wire nuts, or if it is labeled 110, 120, or 240 volts, you have a high voltage system that is not compatible with the GLAS Thermostat. Do not connect your thermostat to these high voltage wires. GLAS is only compatible with 24VAC systems.
WARNING: Risk of Electric Shock.Disconnect the power supply before making electrical connections. Contact with components carrying hazardous voltage can cause electric shock and may result in severe personal injury or death. If you have any doubts about properly installing the device, please contact a professional installer.ADVERTISSEMENT: Risque de décharge électrique.Débrancher l’alimentation avant de réaliser tout branchement élec-trique. Tout contact avec des composants conducteurs de tensions dangereuses risque d’entraîner une décharge électrique et de provo-quer des blessures graves, voire mortelles. (need translation)
Turn o system power2. Turn o the power to your heating or cooling system at your breaker box to avoid electrocution or shock.3. If you want to check your system’s pow-er, adjust the temperature on your current thermostat enough that the system switches into heating or cooling mode. If the system does not power on in a few minutes, it is o.IMPORTANT: Never work with live voltage
Check old wiring4. Remove the front plate of your old ther-mostat and take a picture of the current wiring that shows the wire colors and con-nections. This picture will come in handy when connecting your new thermostat.
Connect optional 4 to 5 wire adapterNote: If you have a C-wire, skip to Step 8. If you do not have a C-wire to power your thermostat, use the included adapter to provide power.5. Remove the cover of your furnace or air handling unit to access the control board.
Connect the adapter6. In your HVAC equipment, disconnect wires from the control board and con-nect them to the open terminals on the adapter.7. Connect the wired terminals on the oth-er side of the adapter back to the control board. (Mount with a included magnet)
Disconnect your old thermostat8. Disconnect your old thermostat and remove the backplateNote: While disconnecting your old ther-mostat, use drywall-safe tape to secure the wires and keep them from falling back into the wall.
Installing your GLAS9. Remove the frontplate by pulling the top of the silver cover towards you.10. Use a level to dry t your GLAS and mark the wall where you plan to hang the thermostat. Then drill in the drywall anchors. 11. Pull all of the wires through the back of the GLAS thermostat.
Attaching your GLAS12. Loosely attach your GLAS to the wall using the included screws.13. Use your level or the level displayed on the device to straighten the thermostat and tighten the screws. Do not overtight-en.
Wiring your GLAS14. Use the picture you took of your old wiring as a reference and connect the wires to the corresponding terminals on your new GLAS. See pages 25-26 for wiring exam-ples.Note: If you have auxiliary devices, such as a humidier, dehumidier, or ventilator, see pages 27-34 for wiring examples.Note: You do not need to have a wire for every terminal.
Attach the front plate15. Make sure any access wire is ush against the wall and press the front plate until you hear a click.
Powering on your HVAC system16. Return to your system switch or break-er box and turn the power back on.17. Conrm that the detected wiring shown on the device screen is correct or tap any terminals incorrectly identied.18. Follow the instructions on the device screen to complete the setup for your HVAC equipment.
WIRING DIAGRAMSNOTE: Wire colors are for reference only. Not every installation will have wires of the same color. If you are unsure on the proper installation of the unit, please contact a licensed electrician or a professional HVAC installer before attempting to install the unit.

Self-Powered Auxiliary Device
Furnace-Powered Auxiliary DeviceAn integrated auxiliary system is built into a furnace or air handler that shares the same power supply as the rest of the system and only requires a single control wire.
Furnace-Powered Auxiliary Device
2-Wire Auxiliary Device without C TerminalAn auxiliary device that has two terminals with the same label (HUM, DEHUM, or AUX) and no C terminal requires a relay pack for operation.1. Connect the relay pack coil between the auxiliary device and C terminal on your GLAS device. 2. Connect the switch side of the relay pack to the two terminals on the AUX device.
2-Wire Auxiliary Device without C Terminal
2-Wire Auxiliary Device with C TerminalAn auxiliary device with one C terminal that does not require a relay pack for opera-tion.1. Connect the C terminal of the device to the C terminal on the furnace or air han-dler.2. Connect the AUX terminal of your GLAS device to the control terminal on the auxiliary device.
