Appendix A: Installation Troubleshooting
The most common problem is not knowing the thermostat operation. If the system is running a
heating or cooling cycle, the set point will turn red for heating and blue for cooling. When the
thermostat turns white, the heat pump, heat strip and furnace should all be off. The fan may continue to
run for a while after the cycle completes. If a fan is left in a manual mode, it will not shut off.

SSID (Network name) and password are both case sensitive.
•
Be sure you are connecting to a 2.4 GHz network and not a 5GHz or 6GHz network.
•
Set the security to WPA2 and TKIP+AES if you are having trouble.
•
The thermostat has a limit of 31 characters for the SSID and 50 for the password.
•
The number of devices limit for the network is not full.
•
The WIFI source is not out of range or metal partitions blocking the signal
•
Reset the router to renew the DHCP lease.
•
If you are in a metal enclosure, try moving the router or thermostat a few inches (even if
temporary) and trying again.
•
If using MAC filtering, add the thermostat to the allowed devices list.
•
Make sure your router does not have the SSID set to “hidden”.
