3 SAF ETY AD VICE

You must isolate the control unit from mains power before carrying out any

assembly or connection work.

The installation and start-up of the control unit should only be carried out by

qualified technical personnel. All work must comply with the applicable na-

tional and local safety regulations.

Always ensure that you isolate the

equipment from mains power before

starting installation or connection work

on the unit's electrical components.

Make sure that you never confuse the

SELV (safety extra low voltage) connec-

tors (sensors, flow transmitters) with the

230 V connectors. This may produce

life-threatening current and cause ir-

reparable damage to the device, at-

tached sensors and equipment.

Solar plant can generate high tempera-

tures. There is therefore a risk of burn

injuries! Take care when installing the

temperature sensors!

When installing sensors, avoid locations

(such as heat sources) that generate

temperatures outside the equipment's

maximum range (>50 °C).

The control unit is not splash- or drip-

proof. Ensure that it is installed in a dry

place.

For safety reasons, the system should

only be operated manually during test-

ing. In this mode of operation, no maxi-

mum temperatures or sensor functional-

ity are monitored.

The system must not be put into opera-

tion if there is recognisable damage to

the control unit, the cables or to the at-

tached pumps and valves.

Before using piping or installation mate-

rials, or attaching pumps and valves,

check that these are suitable for the

temperature levels generated by the

system.

4 UN I T I NS T AL L AT I ON

Only install the control unit in dry interiors not subject to a risk of explosions.

Do not install the unit onto flammable surfaces.

4.1 Opening the unit

Before opening, ensure the unit is isolated

from mains power. If a locking screw has

been attached to the cover of the unit, you

will need to remove this first. The top of the

casing snaps onto the lower part of the unit

on both sides. You can release the top of

the casing by pulling gently on the sides of

the cover (see picture) and then pivoting the

cover upwards.

Continue to pull the

cover upwards until

it snaps into place.

This will enable you

to easily in

stall and

connect up the con-

trol unit

Before switching on or starting up the system:

ensure you have closed the cover – you must be able to hear

and feel it snap into place! Re-attach the locking screw

4.2 Wall installation

If installing the unit on a wall, proceed as follows:

•Drill the mounting holes to match the drilling

template provided

•Screw in the two upper screws so that they pro-

ject 6 mm from the wall

•Open the unit as described above and hang it on

to these two screws. You can now screw in the

two lower screws.

•Tighten all screws only as much as neces-

sary, to avoid damaging the lower part of the

unit casing!

5 EL E C T RIC A L C O NN EC TI O NS –OVERVIEW

Please ensure that you follow the safety advice given

in Section 3

Only open the unit once you have ensured that it has been iso-

lated from mains power and cannot be switched on by acci-

dent.

Before switching on or starting up the system:

ensure that you have closed the cover – you must be able to hear and

feel it snap into place! Make sure you screw in the locking screw on the

front cover!

All electrical connections are made to the

subassembly in the lower part of the unit.

(SELV) connectors for sensors and flow

transmitters are located on the right-hand

side of the subassembly. The 230 V con-

nectors are located on the left-hand side.

The number and location of 230 V and sen-

sor connectors is described on the data

sheet corresponding to the layout used.

5.1 General connection guidelines:

•When connecting all cables, strip the cable covering to a length of approx. 6-8 cm and the

wires to a length of approx. 10 mm.

•For flexible cables, a strain relief device must be present on the interior or exterior of the unit.

On the 230 V side, this can be done by mounting a max. of 4 M12 cable screws. The ends of

the wires must be covered with wire end ferrules. The cables are fed through the apertures

provided and attached to the unit.

•All earth leads must be attached to the terminals marked "PE" (potential earth).

5.2 230 V connectors

One mains power connector is provided,

plus a total of 6 230 V/50 Hz outlets.

Bear in mind the following points concerning

the 230 V connectors:



If the control unit is wired directly into

the mains, it must be possible to isolate

mains power by using a switch external

to the unit.

If the unit is connected using a cable

and earthed plug, this switch is not nec-

essary.

The control unit is designed for use with

230 V/50 Hz mains power. Any attached

pumps and valves must also be rated for

use at this voltage!

iThe neutral lead terminals (N) are con-

nected electrically and are not switched!

iAll switched outputs (A1 to A6) are

electronic 230 V AC make contacts. If

you need potential-free contacts, then

suitable accessory parts can be sup-

plied.

iDepending on the functional layout

used, all outputs can be used as

switched outputs or – using block

modulation – as pump power controls.

iAll output activity is monitored elec-

tronically. A functional check is made

automatically once a day, and can also

be started manually from the "Manual

Operation" menu.

5.3 Connecting sensors

The control unit works with high-precision platinum PT1000 temperature sensors. Between 2

and 10 sensors will be needed, depending on the system setup and functional layout. In some

layouts, the use of radiation sensors and flow transmitters will also be required. Inputs 1 to 7

are suitable for temperature sensors. Inputs 8 to 10 are universal inputs, which can be used for

temperature sensors, radiation sensors or digital inputs.

Temperature sensor installation / ca-

bling:

§Mount the sensors in the corresponding

places on the collector and storage

tank. When doing so, ensure good tem-

perature transfer, using heat-conductive

paste if necessary.

§The temperature sensor cabling can be

extended if required. Cross-sections re-

quired: lengths up to 15 m, 2 x 0.5 mm²;

lengths up to 50 m, 2 x 0.75 mm². Use

shielded extension cables for long con-

nections (e.g. to collector).

Do not insert shielded cable on the

sensor side – clip it and strip it!

§Temperature sensors are connected

according to the system setup. You do

not need to observe polarity for the two

wires when cabling temperature sen-

sors.

When laying sensor cabling, keep it

away from 230 V cables: these can be a

source of electrical interference under

adverse conditions. Keep cabling at

least 15 cm apart.

5.4 Surge protection module

The control unit is provided with fine-level surge protection for all sensor inputs. As a

rule, you will not need to take additional precautions for interior sensors. However, we

recommend additional protection for collector sensors and exterior sensors (sensor

connection box with surge protection). Exterior protective devices must not contain

any additional capacitors, since these may distort measurement readings.
