What to do if my W'eau WMI-004 Heat Pump LED wire controller has no display and the heat pump isn't running?

If there is no display on the LED wire controller and the W'eau Heat Pump is not running, the cause may be no power supply. Check the cable and circuit breaker to ensure they are properly connected.
