Model code [None, P15, PS2, EN1434, CAL3, APAto, SLS]
The model code, which needs to be set for the respective heat meter, can be found in
TV-SK 6311. In general, the default setting of 1434 can be used for most devices.

Reading mode [Coil, Cont, 24h]
The meters can be read either automatically approx. every 24 hours (24h), continuously
(con) or when the coils (= Modbus data points) assigned to the heat meters WMZ1 to
WMZ3 are overwritten with the value 1 over the system bus interface (Coil).
Note!
With reading mode "24h", the displayed values are not updated by reading the status
information again; the values read during the last cycle remain unchanged.
With reading mode "con", the values in the levels are not continuously updated. Reopen
the specific level to get current values.

Meter bus address (Addr?) [0 to 255]
A meter bus address must be unique and correspond with the address preset in the
WMZ. If the preset meter bus address is unknown, a single heat meter connected to the
controller can be assigned meter bus address 254. Address 255 deactivates communica-
tion with the respective heat meter.
