1 Application area / device features
1.1 Application area
The SOLAREG II BASIC DC controllers are high-performance microprocessor-con-
trolled units for controlling the functions of solar thermal systems. They are suitable
for most types of south facing solar thermal systems.
The controller is only suitable for DC operation with a system voltage of 12V. All
connected pumps and valves must be designed accordingly. The controllers are
designed for use in dry rooms as well as residential, business and commercial ap-
plications. Prior to commissioning the device, make sure to verify that the intended
use complies with the applicable regulations.
1.2 Device features

◼
Integrated operating hours counter for storage tank charging
◼
Automatic 12V-battery detection
◼
Extensive functions for system monitoring that display symbols to indicate er-
◼
rors and faults
Storage of all values even during a prolonged mains power supply outage
◼
Various protective functions, such as system protection, collector protection,
◼
recooling and flow monitoring
Generous wiring space
◼
Available accessories:
Temperature sensor PT1000
◼
Sensor connection box
◼

2 Safety instructions
Always completely disconnect the device from the operating voltage before
◼
performing installation or wiring work on the electrical equipment.
Never mix up the connections of the protective low voltage areas (sensor, flow
sensor) with the 12V connections. Otherwise, the device will be destroyed.
Solar power systems can reach high temperatures. Such temperatures pose a
◼
risk of burns! Exercise caution when installing the temperature sensors!
Mount the SOLAREG II controller in a position where it will not be subjected
◼
to excessive operating temperatures (> 50°C) by any external heat sources.For
safety reasons, the system may only remain in manual operation for testing
purposes. In this operating mode, the system does not monitor for maximum
temperatures and sensor functions. If there is any recognisable damage to the
controller, cables or the connected pumps and valves, the system must not be
started.
All installation and wiring
work must only be carried
out on the controller when the
device is disconnected from the
power supply.
The SOLAREG II must only be
connected and commissioned by
qualified personnel. In doing so,
the applicable safety regulations
must be observed.
