• Smart Thermostat HD Installation – Considerations

  • This Smart Thermostat HD requires 24 VAC power, it does not have the option to be battery powered. This is supplied via a common wire, typically identified as C.
  • The Smart Thermostat HD can adapt for situations where there are not enough wires in the bundle at the install location. For example, if you do not have C-Wire but do have 24 VAC available at the HVAC unit, or if you have upgraded your HVAC equipment and now require more control wires. For these scenarios, the Smart Thermostat HD may be installed in a way that requires only 2 wires at the wall. For instructions on this install configuration and further information, please find the Installation Guide in the separate Power Plate box.

  • !CAUTION: Do not test the cooling system if it is cold outside, as this may harm the compressor.
  • Turn off power at the HVAC unit
  • Turn all heating and cooling systems off. This can be done at the circuit breaker.
  • !CAUTION: Do not remove the existing thermostat until power has been turned off at the circuit breaker.
  • Remove existing thermostat
  • Remove the cover from the existing thermostat. Do not disconnect the wires yet.
  • Make sure the wires are identified correctly. If you have an unidentified wire, it may be necessary to identify the wire where it connects to the heating or air conditioning equipment.
  • !CAUTION: Wiring can vary for each manufacturer. Identify all wiring before removing it from the existing thermostat.
  • Take a picture of the wires before you detach them from the existing thermostat for future reference.
  • Once all wires are identified and a picture is taken, disconnect all of the wires and remove the existing thermostat. Remember to secure the wires so they do not fall into the wall.
  • Prep wires if needed
  • Follow these guidelines for safe and secure wire connections:
    • Ensure the wires are a proper gauge between 16-24 AWG (1.5 – 0.5 mm2)
    • Make sure wires have exposed straight ends of the appropriate length.
  • !CAUTION: Verify that the system is 24 VAC. If the old system is labeled as 120 or 240 volts or has wire nuts, the system is high voltage. Do not install the thermostat on a high voltage system. Contact a local HVAC professional for help.

• Smart Thermostat HD Installation – Thermostat Install

  • Level and mount the Thermostat to the wall with the supplied hardware

  • If additional support is necessary, drill holes with a 3/16’’ (#13) drill bit and tap in the drywall anchors.

Troubleshooting

Heating or Cooling does not turn on when the setpoint is above or below the room temperature.| To prevent damaging the compressor, the Smart Thermostat HD inserts a delay when cycling the compressor. This delay is only a few minutes long.| ·         Change the setpoint to 2 degrees beyond the current setpoint and wait 5 minutes, at which point the system should turn on.

·         If this does not work, contact your local HVAC professional.

Heat pump is “cooling when it should be heating” or “heating when it should be cooling”.| Some heat pumps use the O terminal, while others use the B terminal for their reversing valve. Your heat pump may be the opposite type from how

your thermostat is wired.

| ·         Try physically swapping the O or B wire to the opposite. To do this first turn of power to the HVAC system at your

circuit breaker, then

 |  | take off the display of the Smart Thermostat HD, hold down the terminal to remove the wire, remove the wire, hold down the opposite terminal, insert the wire fully, place the display of the Smart Thermostat HD back on the backplate, and return power to your HVAC system.

·         If this does not fix the problem contact your local HVAC professional for help.
