DHW tank maximum temperature
08:60
The solar circuit pump is
switched off when the
actual DHW tank
temperature reaches
140°F (60°C) (maximum
DHW tank temperature).
08:10
to
08:90
Set DHW temperature adjustable
from 50 to 194°F (10 to 90°C).
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 DHW
tank temperature and the set
DHW tank temperature is
less than 5 K.
0A:0
Stagnation time reduction
disabled.
0A:1
to
0A:40
Temperature differential adjustable
from 1 to 40 K.
