22:8
Start temperature differential with
central heating backup (code
"20:4" must be selected) 8 K.
22:2
to
22:30
Start temperature differential adjust-
able from 2 to 30 K.
23:4
Stop temperature differential with
central heating backup (code
"20:4" must be selected) 4 K.
23:2
to
23:30
Stop temperature differential adjust-
able from 1 to 29 K.
24:40

to
24:100
Start temperature for thermostat
function adjustable from 0 to 100 K.

26:1
Priority for DHW cylinder 1
with
cyclical heating.
(Code "20:9" must be selected).
26:0
Priority for DHW cylinder 1
without
cyclical heating.
26:2
Priority for DHW cylinder 2
without
cyclical heating.
26:3
Priority for DHW cylinder 2
with
cy-
clical heating.
26:4
Cyclical heating without priority for
either DHW cylinder.
27:15
Cyclical heating time 15 min.
The DHW cylinder without priority
is heated at most for the duration
of the set cyclical heating time if
the DHW cylinder with priority is al-
ready heated up.
27:5
to
27:60
The cyclical heating time is adjusta-
ble from 5 to 60 min.
28:3
Cyclical pause time 3 min.
After the selected cyclical heating
time for the DHW cylinder without
priority has expired, the rise in col-
lector temperature is captured dur-
ing the cyclical pause time.
28:1
to
28:60
Cyclical pause time is adjustable
from 1 to 60 min.
