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

■

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, fl 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

■

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

■

In case of a fi 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 potential-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 2 ,

- up to 50m 2 x 0.75 mm 2 .

The shield is connected to the earth (PE).

■

Connect the temperature sensors according to the system diagram. The polarity 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.

7.1 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 stratifi 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 off 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 eff 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!

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.
