Troubleshooting

If you have difficulty with your thermostat, please try the following suggestions. Most problems can be corrected quickly and easily.
Display is blank

• Check the circuit breaker and reset if necessary.
• Make sure power switch at heating and cooling system is on.
• Make sure the furnace door is closed securely.

“Wait” appears on the screen

• The compressor protection feature is engaged. Wait 5 minutes for the system to restart safely, without damage to the compressor.

Temperature settings do not change

• If display says “unlock”, thermostat owner has set a lockout setting. If not, verify you are in the correct mode (heat, cool, em heat or auto); see page 1.
• If you are in the correct mode, but you cannot set the heat from 40 °F to 90 °F (4.5 °C to 32 °C), or set the cool from 50 °F to 99 °F (10 °C to 37 °C), you may have range-stops restricting your setting.
  Check with the installer to see if they set range stops.
