Coding in the delivered condition Possible change
11:50 Set solar cylinder temperature
50 °C
■
Target temperature control
switched on (code 10:1):
Temperature at which the solar
heated water is to be stratified
into the DHW cylinder.
■
Extended control functions set to
heat two DHW cylinders (code
20:9):
When the actual temperature of
the DHW cylinder reaches the
set cylinder temperature, heating
is switched over to the 2nd DHW
cylinder.
11:10
to
11:90
The set solar cylinder temperature is
adjustable from 10 to 90 °C.
12:20 Minimum collector temperature
20 °C
The solar circuit pump is only star-
ted when the set minimum collec-
tor temperature is exceeded at the
collector temperature sensor.
12:0 Minimum collector temperature func-
tion switched off
12:1
to
12:90
The minimum collector temperature
is adjustable from 1 to 90 °C.
20:0 No extended control function ena-
bled
20:1 Auxiliary function for DHW heating
20:2 Differential temperature control 2
20:3 Differential temperature control 2
and auxiliary function
20:4 Differential temperature control 2 for
central heating backup
20:5 Thermostat function
20:6 Thermostat function and auxiliary
function
20:7 Solar heating via external heat ex-
changer without additional tempera-
ture sensor
20:8 Solar heating via external heat ex-
changer with additional temperature
sensor
20:9 Solar heating of 2 DHW cylinders
22:8 Start temperature differential for
central heating backup: 8 K
Switching output
sS
is switched on
if the temperature at sensor
/
has exceeded the temperature at
sensor
aÖ
by the selected value.
22:2
to
22:30
Start temperature differential for
central heating backup is adjustable
from 2 to 30 K.
23:4 Stop temperature differential for
central heating backup: 4 K
Switching output
sS
is switched off
if the temperature at sensor
/
un-
dershoots the stop point. The stop
point is the sum of the temperature
at sensor
aÖ
and the value selec-
ted as stop temperature differen-
tial.
23:2
to
23:30
Stop temperature differential for cen-
tral heating backup is adjustable
from 1 to 29 K.
