COMMENT ON DIGITAL MODE
When Digital mode is active and the contact on the input is closed, the product draws much more
current than it does on standby (100 µA instead of 2 µA). To avoid this problem on systems with
slow state changes, please use the mode 'Check the state of the inputs every minute'.
