LED 1
Green LED reports the presence of 3.3V voltage for the power of the probes.
LED 2
Red LED reports an anomaly by flashing:
- a slow flash —> Low CPU voltage
- two slow flashes —> High CPU voltage
- a fast flash —> External TC probe error
- two fast flashes —> Error probe TC Internal
- three fast flashes —> Error probe Humidity
LED 3
Green LED reports how the CPU works:
- a flash —> control board set for mode without external probe
- two flashes —> control board set for mode with external probe
LED 4
Green LED reports the presence of 5V voltage for the power of the board.
