1SAFETYCOMPONENTS
The DS-matics are equipped with two safety valves. The solar circuit safety valve is calibrated to 0.3
MPa and the DHW valve to 0.7 MPa (this valve is optional and it is included with KIT M). The valves
prevent overpressure in the two circuits by discharging the liquid as required when the pressure
exceedsthecalibratedvalues.
The solar power unitisalready adjustedbydefault on supply, so no adjustment is necessary.
2LOCATION
It is very important to choose a correct location for the solar collectors, as an unsuitable location can
reducethesystem’sefficiency:wrongorientation,shadowscastonthesolarcollector,etc.
DOMUSA TEKNIK recommends taking the following indications into account when choosing a
location:
1. Before choosing the location, the accessibility of the site must be taken into account, with a
view to both the installation itselfand for maintenance work on the solar collectors.
2. The solar collectors must face South.Adifference of up to 10°-15° is not significant, but a greater
differencecould considerably effect their efficiency.
3. Ideally, the solar collectors should be installed at an angle of 45º from the horizon line (in
countries at a latitude of 40°). In general, the inclination should be 5° greater than the latitude of
thelocation.Anydifferencefromthisanglewillreducetheirefficiency.
4. Formodelswithbuilt-insupports,theminimumslopemustbe27º(51%).
5. Thesolarcollectorsmustbelevelledforinstallation,withtheupper part horizontal.
6. The weight of the full hot water tank must be taken into account whenchoosingalocation.
7. The premises the hot water tank is to be installed on must be protected from the weather and
any risk of freezing. Thelocationmustbe free from dust or a corrosive atmosphere.
8. The hot water tank must be installed as close as possible to the solar collectors and the
domestic hot water consumption point, to reduce heat loss from the pipes. The minimum and
maximumdistancesindicated belowmustbeobserved.
9. A free height of 500mm must be left above the hot water tank so that maintenance work can be
carried out.
10. The maximum snow load (sk) and main wind speed (vm) values the solar collector-support unit
can withstand with the sloping roof supports are sk = 0.66 and vm = 1.75, and so the system
may only be installed in areas with values lowerthanthese.

3
When installing the solar collectors, ensure that no objects cast shadow on them, particularly in
winter, when the sun is lower in the sky. The minimum distance from an obstacle the solar collectors
can be installed at depends on the height of the obstacle and the latitude of the place of installation,

the accumulator and the solar collectors. If other tube diameters are used it cannot be guaranteed to
work properly, and there may also be riskofnoiseonfunctioning.

3SOLARPOWERUNIT
3.1 Models
There are two families of hot water tank, depending on the type of power unit: DS-matic and DS-matic
Duo.
DS-MATIC
The power unit of the DS-matic models is designed for controlling the solar pumps only. It is equipped
with two sensor inputs for this purpose - the collector sensor input and the hot water tank sensor
input - and two outputs for the solar pumps. The power unit activates or deactivates the pumps
dependingontheparametersprogrammed.
Figure 2
DS-MATIC DUO
This power unit is designed to control a heating-only boiler as a back-up power supply for the DS-
matic Duo range. Apart from all the DS-matic power
unit inputs and outputs, it therefore has another
input for the sensor on the upper part of the hot
water tank (for measuring the temperature of the
water heated by the boiler) and another switched
outputfortheboiler.
The connection of the sensor to the upper part of
the hot water tank is different depending on
whether the back-up boiler has an input for a thermostat or an electronic sensor. Follow the
instructionsinpoint7.5.1Electricaldiagramforthispurpose(seepage46).

3.3 Equipment
The solar power unit is equipment with different sensors, according to the model. The different types
of sensor depend on the hot water tank volume and on whether it is a DS-matic or a DS-matic Duo
model.

3.4.2 Adjustment parameters
The adjustment parameters regulate the functioning of the hot water tank. These parameters can be
adjustedtochangethewaythe system functions, adjusting them to eachparticularuser’sneeds.
There are two types of adjustment parameters: the basic parameters, which affect the hot water tank
setpoint temperatures, and the advanced parameters, foradjustingthefunctioningofthesystem.
The system is supplied with all the parameters programmed for optimum functioning, so none of the
values need to be adjusted.
As is the case with the display parameters, the adjustment parameters are also different on the DS-
matic and the DS-matic Duo models, and the adjustment parameters are therefore shown for each
typeofpowerunit.

4STARTINGUPTHE INSTALLATION
Before starting up the installation, ensure the safety valves and the safety unit (if the installation has
one) are working correctly, and check that the accumulator and the solar circuit have been filled
followingthe instructions provided in point 8 of the instructions booklet.
5FROST PROTECTION
The DS-matic pumps are deactivated when the temperature difference between the collector and the
accumulator is less than the value programmed (4ºC by default). This means the liquid in the solar
heating circuit flows down from the solar collectors to the accumulator and there is no risk of it
freezing.
In any case, to prevent risk in case of incomplete draining, DOMUSA TEKNIK supplies an inhibitor
liquid, which in addition to protecting the different components of the installation from corrosion,
also serves as an anti-freeze. DOMUSA TEKNIK inhibitor liquid has a resistance and heat transmission
making it suitable for use in solar installations. DOMUSA TEKNIK recommends using a minimum
concentrationof 30% inhibitor liquid.
!IMPORTANT:
THE INHIBITOR LIQUID MUST ALWAYS BE MIXED WITH WATER BEFORE USE, AS OTHERWISE IT
COULD DAMAGE THE INSTALLATION.
!IMPORTANT:
DOMUSA TEKNIK WILL ONLY BE LIABLE FOR THE CORRECT FUNCTIONING OF THE SYSTEM IF IT HAS
BEEN FILLED WITH DOMUSA TEKNIK INHIBITOR LIQUID.

6DRAININGTHE SOLAR CIRCUIT
If the solar circuit needs draining, the
procedureis as follows:
1.Connect a hose to the filling/emptying
valve and another hose to the level valve,
and run them to a drain.
2.Runthe hoses to a suitable container.
3.Open the filling/emptying valve and the
levelvalve.
4.Completely drain the solar heating circuit
(seetable below).
5.Disconnectthe hoses used.

7SWITCHINGOFF THE UNIT
If you wish to deactivate the unit, adjust the HNS parameter to value 1, so that the pumps are
permanently deactivated.
In case of prolonged absence, apart from deactivating the pumps (or disconnecting the unit from the
electricity supply) you should also drain the accumulator primary circuit, following the instructions
givenin the previous point.
8MAINTENANCE
Maintenance must only be carried out by qualified staff. All work carried out on the system must be
done by the Official Technical Assistance Service, as changing the configuration could cause
functioningerrors and damageto thesystem and its surrounding environment.

ensurea minimum concentration of 30% of inhibitor liquid.
8Checkthe plates are self-draining
Set the pumps running (see point ¡Error! No se encuentra el origen de la referencia. of Intallation
guide), ensure the water is returning to the hot water tank and then disconnect the pumps. When 15
