Troubleshooting
Lost Signal
If the no-Wi-Fi indicator displays in place of the Wi-Fi strength indicator in the upper right hand corner of the home screen:
- Check another device to be sure Wi-Fi is working in your home; if not, call your Internet Service Provider.
- Move the router.
- Restart the thermostat: remove it from the wallplate, wait 10 seconds, and snap it back onto the wallplate. Return to Step 1 of Connecting to your Wi-Fi network.
Error Codes
For certain problems, the thermostat screen will display a code that identifies the trouble. Initially, error codes are displayed alone in the time area of the screen; after a few minutes, the home screen is displayed and the code alternates with the time.
| E01 | During Wi-Fi Setup, the router lost power. | • Ensure your router has power.
• If trying to connect to a hidden or manually added network, confirm the router has power and is working. |
|
| E02 Invalid Wi-Fi password. This code displays for 30 seconds, then the thermostat will re- enter Wi-Fi Setup mode. | • Re-enter password for your home Wi-Fi network.
• Repeat setup process and confirm your password for your home Wi-Fi network. |
||
| E42 Router is not issuing an IP ad- dress to the thermostat. | • Wait for 30 minutes, connection can take several minutes.
• If still no connection, remove thermostat from wallplate for 10 seconds, then reconnect it. • Verify your router is correctly setup to automatically give IP addresses. |
M33998A | |
| E43 No internet connection. Ther- mostat cannot communicate to Total Connect Comfort. | • Make sure the Internet cable is plugged in.
• Reboot the router. |
||
| E99 | General error | Remove thermostat from wallplate for 10 seconds, then recon- nect it. | |
If you have difficulty with your thermostat, please try the following suggestions. Most problems can be corrected quickly and easily.
Display is blank
- Check circuit breaker and reset if necessary.
- Make sure power switch at heating and cooling system is on.
- Make sure furnace door is closed securely.
- Make sure C wire is connected.
Fan does not turn on when heat is required
Check Function 3: Heating Fan Control to make sure it is set to match the heating equipment
Cool On or Heat On is flashing on the screen
Compressor protection feature is engaged. Wait 5 minutes for the system to restart safely, without damage to the compressor.
Heat pump issues cool air in heat mode, or warm air in cool mode
Check Function 2: Heat Pump Changeover Valve to make sure it is properly configured for your system.
Heating system is running in cool mode
Check Function 1: System Type to make sure it is set to match the heating and cooling equipment
Heating and cooling equipment are running at the same time
- Check Function 1: System Type to make sure it is set to match the heating and cooling equipment.
- Grasp and pull thermostat away from wallplate. Check to make sure bare wires are not touching each other.
- Check thermostat wiring is correct
Special functions
Auto Changeover (Setup Function 12): When set to Auto, the thermostat automatically selects heating or cooling depending on the indoor temperature. The thermostat will automatically adjust heat and cool settings to maintain a 3-degree separation (fixed). Note: If you select Auto Changeover Only, the System Setting on the thermostat will stay locked in the Auto position, preventing the user from changing it to Em Heat, Heat, Cool or Off.
Adaptive Intelligent Recovery™ (Setup Function 13): Allows the thermostat to “learn” how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the scheduled time.
Compressor Protection (Setup Function 15): Forces the compressor to wait a few minutes before restarting, to prevent damage. During the wait time, the message Cool On or Heat On (heat pumps only) will flash on the display.
