Solar circuit pump is not
speed-controlled.
The solar circuit pump is
switched off when the
actual DHW tank
temperature reaches
140°F (60°C) (maximum
DHW tank temperature).
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.
Solar circuit flow rate at
the maximum pump speed
7 L/minute.
No extended control
function enabled.
Possible change
02:1 Solar circuit pump is speed-
controlled with wave packet
control.
02:2 Solar circuit pump is speed-
controlled with PWM control.
08:10 Set DHW temperature adjustable
to from 50 to 194°F (10 to 90°C).
