1.1 Application area
The SOLAREG II ENERGY controllers are high-performance microprocessor-con-
trolled units for controlling the functions of solar thermal systems. The SOLAREG II
ENERGY perfectly controls solar power systems equipped with one collector and
one storage tank.
The controllers are designed for use in dry rooms as well as residential, business
and commercial applications. Prior to commissioning the device, make sure to
verify that the intended use complies with the applicable regulations.
1.2 Device features
The SOLAREG II generation of controllers is equipped with the following features:
Intuitive operating menu with graphic symbols and four operating buttons
◼
Adjustable values
◼
Integrated operating hours counter for storage tank charging
◼
Start function for systems equipped with tube collectors
◼
Integrated energy yield measurement
◼
(optional, only in conjunction with the yield measurement set)
Solar circuit pump RPM controll or switching controll
◼
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
◼
Yield measurement set (incl. tube sensor)
◼
Sensor connection box
◼
Immersion sleeves
◼
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 230V connections. Otherwise, the device will be destroyed. The
device and the connected sensors may carry deadly voltages.
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.
