At the factory, USDT 3002 is set
to control a standard solar water
heating system with an auxiliary relay
to divert surplus heat. The auxiliary
relay can be used to maintain the
tank temperature, protect the system
from overheating or provide another
heat source to heat the storage tank.
The controller has inputs for four
PT1000-sensors.
The fourth sensor may be used as
for an additional temperature reading
or for a flow meter. A 3-key-panel
below a large LCD serves as the
user interface. Simple icons give
information about the function and
operational mode of the controller
and the system performance.
