Info codes / alarms
Info codes can consist of up to 4 characters. Each character
has values 0 ... F.

Active info codes are added and displayed simultaneously,
even if it is more than one error.
3 - corresponds to error 2 + 1
5 - corresponds to error 4 + 1
7 - corresponds to error 4 + 2 + 1
9 - corresponds to error 8 + 1
A - corresponds to error 8 + 2
B - corresponds to error 8 + 2 + 1
D - corresponds to error 8 + 4 + 1
E - corresponds to error 8 + 4 + 2
F - corresponds to error 8 + 4 + 2 +1
When any info code is ≥ 8, measurement of energy and vol-
ume stops. Operating time without error stops counting.
When the flow sensor shows error 4 during operation, the time
in the register is counted "flow over q> 1.2 * qs"
