The solar circuit pump starts
when the collector temperature
exceeds the actual DHW tank
temperature by 8 K.
The solar circuit pump is switched
off when the differential between
the collector temperature and the
actual DHW tank temperature is
less than 4 K.
Solar circuit pump (stepped)
is not speed-controlled
The temperature differential
between the collector
temperature and actual DHW
tank temperature is regulated
to 10 K.
Controller amplification of the
speed control 4%/K.
Minimum speed of the solar
circuit pump 10% of the
maximum speed.
Maximum speed of the solar
circuit pump 75% of the
maximum possible speed.
Interval function of the solar
circuit pump switched off.
The solar circuit pump is
switched off when the
actual DHW tank temperature
reaches 140°F (60°C)
(maximum DHW tank
temperature).

Possible change
00:2 The differential between
to the actual DHW tank temperature
00:30 and the start point for the solar
circuit pump can be adjusted from
2 to 30 K.
01:1 The differential between the
to actual DHW tank temperature and
01:29 the stop point for the solar circuit
pump can be adjusted from 1 to
29 K.
02:1 Solar circuit pump is speed-
controlled with wave packet
control.
02:2 Solar circuit pump is speed-
controlled with PWM control.
03:5 The differential temperature
to control between collector
03:20 temperature and actual DHW tank
temperature can be adjusted from
5 to 20 K.
04:1 Controller amplification adjustable
to from 1 to 10%/K.
04:10
05:2 Minimum speed of the solar
to circuit pump is adjustable from
05:100 2 to 100%.
06:1 Maximum speed of the solar
to circuit pump is adjustable from 1
06:100 to 100%.
07:1 Interval function of the solar
circuit pump switched on. To
capture the collector temperature
more accurately, the solar circuit
pump starts for short cycles.
08:10 The maximum DHW tank
to temperature can be adjusted
08:90 from 50 to 194°F (10 to 90°C).
