1 Application area / device features

1.1 Application area

SOLAREG II VISION plus controllers are high-performance microprocessor-control­led units for controlling the functions of solar thermal systems. The SOLAREG II
VISION plus perfectly controls solar power systems equipped with up to two
collectors or two storage tanks and can be used for numerous system types. 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

■

Illuminated display

■

Adjustable control values

■

Solar circuit pump RPM control or switching control

■

Start function for systems equipped with tube collectors

■

Integrated operating hours counter for storage tank charging

■

Extensive functions for system monitoring that display symbols to indicate
errors and faults

■

Integrated energy yield measurement
(optional, only in conjunction with the yield measurement set)

Storage of all values even during a prolonged mains power supply outage

■

Various protective functions, such as system protection, collector protection,

■

recooling and anti-freeze protection
Individually operated independent controller that can be programmed with

■

three time frames
Generous wiring space

■

Real-time clock function

■

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,  ow
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.

3 Mounting the device

3.1 Opening the device

Prior to opening the device, make sure to disconnect the mains voltage and
ensure that it cannot be switched back on again! The upper part of the housing
is locked to the lower part using two latches. Pull the side pieces (cover plates) of
the upper part of the housing outwards (see picture) to unlatch it and upwards
until the cover plate is opened.

3.2 Wall mounting

The device is mounted on the marked points. A drilling template is provided with
the device. Insert the "Quick Info" card provided with the device into the pocket
provided on the back of the device. The "Quick Info" card provides the user with
an overview of the functions to facilitate rapid device operation.

3.3 Connections

a

a

The following points must be followed for the 230V connections:

■

In case of a  xed mains connection, there must be a switch installed outside
the controller that can disconnect the device from the mains power supply.
This switch is not required if the mains supply is connected using a cable and
an earthed mains plug.

The controllers are designed to operate using a 230V/50Hz mains supply. The

■

pumps and valves to be connected must be designed for this voltage!
All protective conductors must be connected to terminals marked with PE.

■

The neutral conductor terminals (N) are electrically connected and are not

■

switched!
All switching outputs (A1/A2/A3) are electronic 230V~ N/O contacts. If poten-

■

tial-free contacts are required, the appropriate corresponding accessories are
available

3.4 Temperature sensor connection

The SOLAREG II VISION PLUS devices use PT1000 precision platinum temperature
sensors. Depending on the system type and functional scope, 2 to 6 sensors are
required.

Mounting / wiring the temperature sensors:

Mount the sensors on the collector and the storage tank. Ensure proper heat

■

transfer and use heat-conducting paste if necessary.
Cross-sections for cable extensions (shielded):

■

- up to 15m 2 x 0.5 mm

- up to 50m 2 x 0.75 mm
The shield is connected to the earth (PE).

Connect the temperature sensors according to the system diagram. The polar-

■

ity of both conductors for the temperature sensors is irrelevant.
Sensor cables must be laid separately from 230V wires.

■

Sensor connection boxes equipped with surge protection should be used for

■

collector sensors and cable extensions.

7 Controller functions

7.1 General controller functions

The controller compares the temperatures of the various measuring points and
optimally charges the storage tank. If the collector temperature exceeds the
storage tank temperature, the solar circuit pump is switched on. Monitoring and
protection functions ensure safe operation.

7.1.1 Dual storage tank systems (diagram 1 and 2)

Examples of dual storage tank systems:

two separate storage tanks

■

one strati ed storage tank

■

one storage tank and a swimming pool, etc.

■

The controller detects the temperature changes in the collector and the storage
media, determines the primary and secondary charging while, of course, taking
into consideration the charging duration as well as an interruption of this func­tion along with a waiting period to monitor the collector temperature.

7.2 Protective functions

The controller is equipped with the following protective functions.

7.2.1 Collector protection

If the storage tank has reached the set maximum temperature and the collector
temperature exceeds the set collector protection temperature (line 1), the solar
circuit pump is switched on. The solar circuit pump is switched o once the col­lector temperature is 10K below the maximum value.

In this case, the storage tank is charged up to 95°C regardless of the set maximum
temperature.

7.2.2 Recooling (Holiday function)

The collector protection function is only e ective if the storage tank temperature
is below the temperature limit (95°). Therefore, during the holiday period, for
example, the storage tank is discharged at night to the set recooling temperature.

Make sure not to activate this function together with the backup heating!

7.2.3 System protection

If the collector temperature exceeds the collector protection temperature (see

If the collector temperature drops below the collector protection temperature,
the solar circuit pump is switched on.

The function is always activated.

7.2.4 Anti-freeze protection

This function must be activated if the water or glycol mixture can freeze.
If the temperature at the anti-freeze sensor (line 12) drops below the set value,

the solar circuit pump is activated and heats the solar circuit using the heat ex­changer in the storage tank.

12 Warranty conditions

The SOLAREG II controllers are carefully produced and tested on an automatic
testing station. If any failures occur,  rst check if there are any operation / setting
or system errors. Furthermore, check the pump and temperature sensor connec­tions.

PROZEDA GmbH provides a 2-year warranty starting at the date of purchase and
according to the following conditions.

a) The warranty comes into e ect if the purchased good exhibits a material or

quality defect. If the defect is caused by improper handling, by exceeding the
permitted values stated in the speci cations, improper wiring, invalid tech­nical modi cations to the device performed by the buyer or by an another
company other than PROZEDA GmbH, the warranty shall be void.

b) The warranty requires a written notice that describes the defect in detail as

well as a copy of the customer invoice.
PROZEDA GmbH can choose to ful l the guarantee, at its own discretion, by
one of the following measures

these conditions shall come into e ect.
c) Any further warranty (redhibitory action, reduction of price) is excluded.
Warranty claims may only be submitted by the customer and are non-transfer-

able.
If a defect occurs during the warranty period, please contact the supplier / in-

staller. When returning the device for warranty service, please make sure to send
a description of the error and, if possible, the system diagram along with the
wiring diagram.
