The adjacent display subsequently appears with the remaining
warm-up period which is counted down in seconds to 00:00
(minutes:seconds).
In the 󹪝rst 5 minutes of the warm-up phase, the 4 mA value is
always transferred over the analog interface and the 'Function
control (FCTRL)' status is set. This does not represent an error.
