Coding in the delivered condition
Cylinder maximum temperature
08:60 The solar circuit pump will
stop when the actual cyl-
inder temperature rea-
ches 60 °C (maximum
cylinder temperature).
Stagnation time reduction
0A:5 To protect the system
components and heat
transfer medium, the
speed of the solar circuit
pump is reduced when
the differential between
the actual cylinder tem-
perature and the set cyl-
inder temperature is less
than 5 K.
Flow rate solar circuit
0F:70 The flow rate of the solar
circuit at the maximum
pump speed is set to
7 l/min.
(cont.)
Possible change
08:10 The maximum cylinder
to temperature can be adjus-
08:90 ted from 10 to 90 °C.
0A:0 The differential between
to the set cylinder tempera-
0A:40 ture and the start point for
reducing the stagnation
time can be adjusted from
0 to 40 K.
0F:1 Flow rate of the solar circuit
to adjustable from 0.1 to
0F:255 25.5 l/min
