Power limit on eight more hydro board softwares. The experimental power limit (Settings → Experimental) knew one hydro board software, 18002904. It now has the addresses of the eight others the targets already know: 17014006, 17019A04, 20002203, 20007903, 20007904, 20017704, 20017705 and 22009C02. They come from the boards' software, like the targets, and none has been tried on a real unit yet: tick the option, check that the card shows your software and the unit's own kind and limit 1 (20 kW or 50 A on most units) before applying anything, and report on #599. The softwares from 20002203 on keep a separate active limit for the current kind; ESPAltherma reads that one when the unit is set to amps. 20002202 stays "not available" for the limit.
20002202 targets corrected. The hot water and leaving water addresses of that software were two bytes too high (they pointed at the leaving water and the additional zone curves). Nothing had been written on such a unit. The two-step check asked on #599 stands with this release.
Update: System → Firmware update → Check for an update, or the web installer. Card: 1.0.28 on HACS (the day figures translated, Dutch 3-way valve wording).
