Set DHW temperature reheating suppression
67:40 For solar DHW heating: set DHW
temperature 40 °C. Reheating is
suppressed above the selected set
temperature. The heat generator
starts as backup if the rise in the
cylinder temperature is insufficient. 67:0
to
67:95 Set DHW temperature adjustable
from 0 to 95 °C (limited by appli-
ance-specific parameters)
Enable DHW circulation pump
73:0 DHW circulation pump: "ON" ac-
cording to time program 73:1
to
73:6 "ON" from once per hour for 5 min
up to 6 times per hour for 5 min dur-
ing the time program
73:7 Constantly "ON"
"Solar"
Select "Solar" (see page 63). Note
The "Solar" group is only displayed if a solar control
module, type SM1, is connected.

Speed control solar circuit pump
02:... Data dependent on the software
version of solar control module
SM1 02:0 Solar circuit pump is not speed-con-
trolled
02:1 With wave packet control function
Never adjust
02:2 Solar circuit pump is speed-control-
led with PWM control
Maximum cylinder temperature
08:60 Set DHW temperature (maximum
cylinder temperature) 60 °C. 08:10
to
08:90 Set DHW temperature adjustable
from 10 to 90 °C.
Stagnation time reduction
0A:5 Temperature differential for stagna-
tion time reduction (reduction in
the speed of the solar circuit pump
to protect system components and
heat transfer medium) 5 K. 0A:0 Stagnation time reduction not active.
0A:1
to
0A:40 Temperature differential adjustable
from 1 to 40 K.
Flow rate solar circuit
0F:70 Solar circuit flow rate at the maxi-
mum pump speed 7 l/min. 0F:1
to
0F:255 Flow rate adjustable from 0.1 to
25.5 l/min,
