of our solar controller family. The controller monitors
and controls solar thermal energy systems with a collector
array, a storage tank and alternatively with an appropriate
back-up heating or circulation pump. Apart from controlling
the solar system, the controller also performs important
system monitoring and safety functions. The system
parameters and measured values can be viewed and modified
via a 2 x 16-digit menu-driven LCD-Display.
The amount of solar energy fed from the collector array into
the storage tank can be read from the LCD Display at any time,
thanks to a flow meter with pulse output. The controller has
a maximum of five inputs for temperature measurement, a
digital pulse input for recording heat volume data, and two
outputs for controlling pumps. A programmable timer with
selectable switching times for controlling a solar circuit pump
is integrated into the unit. Installation mistakes are avoided
from the very beginning through the automatic recognition of
the temperature sensors. The components delivered with the
controller include a collector temperature sensor and two
storage tank sensors.
