Waiting for Equipment Message

The thermostat may display:

Waiting for equipment

This message indicates that the compressor protection feature is active.

The compressor protection delay prevents the equipment from restarting too quickly.

Recommended Action

Wait approximately five minutes for the system to restart safely.

This delay helps prevent compressor damage.

Cannot Change the Temperature Setpoint

The thermostat may restrict temperature adjustments for several reasons.

Owner-Defined Lockout

If the display shows Unlock, the thermostat owner may have enabled a lockout setting.

The lockout must be addressed before unrestricted adjustment is possible.

Incorrect Operating Mode

Confirm that the thermostat is operating in the correct mode.

Modes referenced in the troubleshooting instructions include Heat, Cool, Emergency Heat, and Auto.

Installer-Configured Range Stops

The thermostat may have temperature limits set by the installer.

The troubleshooting instructions reference:

If the correct operating mode is selected but the desired temperature within the referenced range cannot be set, range stops may be restricting the adjustment.

Recommended Action

Contact the installer to determine whether temperature range stops were configured.

WiFi Troubleshooting

WiFi connection failures can occur because of incorrect credentials, router address configuration, or internet connectivity problems.
