1 Application area / device features

1.1 Application area

VISION controllers are high-performance microprocessor-controlled units for
controlling the functions of solar thermal systems. The VISION 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 controller 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 ■
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, 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 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 controller must only be
connected and commissioned
by qualified personnel. In doing
so, the applicable safety regula­tions must be observed.

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.

The controller must only

be installed in dry and
non-explosive areas. Mounting
the controller on an inflammab­le surface is prohibited

Prior to switching on or

commissioning the
device: make sure to close the
cover until both sides securely
lock into place!

3.3 Connections

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-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 VISION 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 mm2,

- up to 50m 2 x 0.75 mm2.
The shield is connected to the earth (PE).

Connect the temperature sensors according to the system diagram. The polar-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 storage tank is being charged through the pump on output A1 (A2) up to
adjusted maximal temperature so long as the collector temperature becomes
higher by a certain amount than the storage tank temperature. Switching action
can be adjusted through dTmax (dTon) and dTmin (dTo), but dTon cannot get
lower than dTo + 1K.

7.1.2 RPM control

The A1 and A2 outputs can be operated using an RPM control.

7.1.3 Independent controller

This function is reserved for output 3 and can be allocated the following functions:

Cooling ■
Heating ■
Dierence controller ■

Cooling

To increase the energy productivity of solar system it may be useful to „by­pass“the solar energy at reaching a certain storage tank temperature or to take it
from the storage tank. If the temperature of the storage tank (S2) goes over the
temperature barrier Tstmax – 5K (adjusted maximal storage tank temperature –
5K), the switch output A3 is switched on. Switching o takes place at lower devia­tion of this 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!

8 System monitoring

If an error occurs, the ashing symbol is generally displayed.

8.1 Sensor monitoring

The connected sensors and sensor cables are monitored for interruptions and
short-circuits. Errors are indicated by the symbol. You can nd the error source
by scrolling up or down the Info menu.

8.2 Flow monitoring

The controller is programmed to display a message if the ow is interrupted, e.g.
pump fault or if vapour is in the system. This message, however, does not switch
o the pump.
