4. Control parameter and indication channels
4.1 Channel-overview
Legend:
x
Corresponding channel is available.
x*
Corresponding channel is available if the appropriate option
is activated.
Corresponding channel is only available if the option heat
quantity measurement is activated (OHQM).
MEDT
The channel antifreeze content (MED%) is only shown
if the antifreeze is not water or Tyfocor LS / G-LS
(MEDT 0 or 3). Adjustments concerning the antifreeze
content will only make sense if the antifreeze is used in the
solar circuit.
Corresponding channel is only available if the option heat
quantity measurement is deactivated (OHQM).
Please note:
S3 and S4 are only indicated in case of sensors connected
