allows the unit to restart automatically. The module
automatically stores the current settings (not including

• If there is a power failure while the unit is running, the
compressor starts 3 minutes after the unit restarts. If
the unit was already off before the power failure, the
compressor starts 1 minute after the unit restarts.
