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).
The solar circuit pump stops
if the collector temperature
reaches 266°F (130°C)
(maximum collector temperature
to protect the system
components)
