Source Pump, Charging Pump and circulation pump missing on TTC05

[Optic00]

I am missing at least those 3 sensors on my Tecalor TTC-05(cool) via ISG, everything else works perfect (many thanks for that!)
I am trying to figure out how to add those sensors but don't understand how the modbus-adresses are generated in the source to add them, i found those references but they are not available in HA.

CIRCULATION_PUMP = "circulation_pump"
DHW_CHARGING_PUMP = "dhw_charging_pump"
SOURCE_PUMP = "source_pump"

i think i remember that those status details were only available via ISG web and the only way to get them via modbus was through a manual edit of the ISG config as described here: https://loxwiki.atlassian.net/wiki/spaces/LOX/pages/1576274868/zus+tzliche+Objekte+im+ISGweb+f+r+modbus+TCP+freischalten
