1.1 Application area
SOLAREG II BASIC HE controllers are high-performance microprocessor-controlled
units for controlling the functions of solar thermal systems using high-eciency
pumps. SOLAREG II BASIC HE is the ideal controller for systems with one collector
array and one storage tank. The controllers are designed for use in dry areas and
for residential, business and commercial applications. If you want to use the unit
for other purposes, check applicable statutory regulations before use.
1.2 Device features
The SOLAREG II generation of controllers is equipped with the following features:
Intuitive user menus with icons and four control buttons ■
Adjustable control values ■
RPM control of the solar circuit pump via PWM, analogue signal or 230 V block ■
modulation
Drain-back function ■
Integrated operating hours counter for storage tank charging ■
Extensive functions for system monitoring, using symbols to indicate errors ■
and faults
Storage of all values, even during prolonged mains power supply outage ■
Various protective functions: system and collector protection, recooling, anti- ■
freeze protection and through-ow monitoring
Generous wiring space ■
Available accessories:
PT1000 temperature sensor ■
Sensor connection box ■
Immersion sleeves ■
2 Safety instructions
Always ensure that you isolate the device from the mains power supply before ■
starting installation or wiring work on its electrical components. Make sure
that you never confuse the SELV (safety extra low voltage) connectors (sensor,
ow transmitter) with the 230 V connectors: this will destroy the device. Life-
threatening voltages may be present in both the device and the connected
sensors.
Solar power systems can generate high temperatures. There is therefore a risk ■
of burn injuries! Exercise caution when installing the temperature sensors!
Mount the SOLAREG II in a location where it will not be subjected to excessive ■
operating temperatures (>50 °C) by any external heat sources.
For safety reasons, the system should only be operated manually during test-
ing. In this operating mode, the system does not monitor maximum tempera-
tures or sensor functions. Do not operate the system if there is recognisable
damage to the controller, cables or the connected pumps and valves.
You must isolate the
control unit from mains
power before carrying out any
assembly or wiring work.
The connection and start-up of
the SOLAREG II should only be
carried out by qualified techni-
cal personnel. All work must
comply with the applicable
safety regulations.
