What does the 'Wait' message on the thermostat display mean?

The 'Wait' message appears on the display when the compressor protection (minimum off timer) is active, preventing the compressor from restarting too soon after a shutdown. This is a built-in feature to protect the compressor from restarting too early after a shutdown. The minimum off timer is activated after the compressor turns off and can be set from Off to 1–5 minutes via ISU 387.
