3 INSTALLATION INSTRUCTIONS
The boiler must be installed by personnel authorised by the Department of Industry in accordance
with the applicable regulations and standards in force. However, the following recommendations
must be complied with when installing the boiler:
3.1 Location and assembly of the boiler/hot water tank unit
The boiler must be installed in a sufficiently ventilated site. The boiler has an integrated solar
capture system and must therefore be located at a lower level than the solar collector installation.
The two modules are to be placed back-to-back and aligned at the front. The assembly may be
made either towards the right or towards the left. Each module is supplied with levelling screws on
its base, accessible from the front, as shown in the picture below.
When you have correctly positioned the modules, interconnect them hydraulically using the two
flexible connection tubes supplied inside the boiler module. Open the door to access them.
Connect socket “A” on the rear of the accumulator module to the corresponding socket “A” of the
boiler module, and socket “B” to the corresponding socket “B”, as shown in the picture below.
Finally, connect the two modules electrically using the connectors on the rear of each module, as
shown in the picture below.
The boiler must be accessible from the side for maintenance purposes. The solar accumulator
module may be placed on either side of the back-up boiler module for this purpose.

3.2 Hydraulic installation of the heating and D.H.W. circuit.
The hydraulic installation must be made by qualified personnel. The applicable installation
legislation is to be complied with, and the following recommendations should also be taken into
account:
- The inside of the installation piping should be thoroughly cleaned before switching on the
boiler.
- Ensure the two modules have been hydraulically interconnected before connecting the boiler.
(See section “3.1”)
- We recommend inserting cut-off valves between the installation piping and the boiler to
simplify maintenance tasks.
- If the boiler is installed at a lower height than the heating installation, it is recommendable to
create a siphon at the boiler outlet, to prevent the installation from heating up due to natural
convection when heating is not required.
- For correct boiler functioning, there must be a pressure of at least 0.5 bar in the domestic hot
water circuit.
- When the DHW supply pressure is over 5 bars, a pressure reducer must be fitted.
- It is recommended to install a thermostatic mixing valve at the DHW outlet to protect against
burns and to guarantee a constant, stable supply of hot water.
- Before starting up the unit, it is essential to install the condensation siphon supplied with the
boiler documentation on the condensation drain tube
on the back of the boiler.
- The condensation pipe should lead to a drain outlet,
as the Evolution boiler is a condensation boiler and a
large amount of water may be generated. This
connection should be made in accordance with the
regulations for draining off condensation water to the
drain network.
- Fill the siphon with water before starting up the unit, to
prevent fumes coming out of it.
3.3 Fuel installation
The Evolution Solar HDX boiler is supplied with a Domestic sealed oil burner (see model in
“
Technical Characteristics
”). To correctly make the fuel installation, proceed in accordance with the
burner instructions enclosed with this manual (see “
Burner
” section).
The oil line installation and start-up of the burner must be carried out by qualified, authorised
personnel.
7
3.4 Electrical Connection
The boiler is equipped for connection at 230 V~, 50 Hz to terminals 1 and 2 of terminal strip J1 (see
“
Electrical Connection Diagram
”). Remember to earth the appliance.
The boiler has two terminal strips, TA1 (J5) and TA2 (J6) for connecting room thermostats or room
chronothermostats (see “
Electrical Connection Diagram
”) for remote control of heating circuits 1
and 2 respectively. To correctly connect the room thermostats, firstly remove the bridge joining the
terminals of terminal strip TA1. For connection to TA2, simply connect the thermostat to the
terminal strip.
IMPORTANT: Before carrying out any work on the boiler’s electrical installation, always ensure it
is disconnected from the mains.
IMPORTANT: To access the electrical connection terminal strip, remove the protection box
under the main board, as shown in the picture below.
Remove the protective box to
access the terminal strip
3.5 Installing heating circuit 2 (Optional)
All the models in the Evolution Solar HDX range of boilers are supplied equipped with a circulation
pump connected to a heating circuit, circuit 1 (BC
1
). In addition to this circuit, all the models are
designed to control a second heating circulation pump, in a second heating circuit, circuit 2 (BC
2
).
The hydraulic installation of heating circuit 2 should be made using the optional flow circuit (IC')
on the rear of the boiler (see "Diagrams and Measurements").
A circulation pump and a shut-off valve or electrovalve will need to be included in heating circuit Nº
2. This pump must be electrically connected between terminals N and 8 on the supply connector
block J2 (see “Electrical Connection Diagram").
Evolution Solar HDX

3.6 Installing the solar circuit
The solar circuit integrated in the boiler must be installed by qualified personnel. The solar circuit
basically consists of a dual-chamber domestic hot water storage tank for exchanging heat with the
domestic hot water, two solar circulation pumps, a flow regulator and one or two solar collectors
for exchanging heat with the sun.
To make optimum use of the solar energy, take special care when locating and positioning the solar
collector. Read the “Location of the Solar Collector” section carefully to obtain full performance
from the circuit. To correctly assemble the solar collector and its corresponding supports, carefully
follow the assembly instructions included with the same.
The hydraulic connection between the solar collector and the boiler is made using the solar inlet
socket "ES" and the solar return socket "RS". See "Diagrams and Measurements". When making the
solar circuit and the hydraulic connection between the solar collector and the boiler, the following
limitations must be taken into account:
Min. height
(G)
Max. height
(H)
Max. horizontal L. (flow
and return) (L)
Max. total length
Min. slope ( α )
Piping Ø
0.5 m. 10.9 m. 20 m. 40 m. 4% Ø 12 mm.
When the solar circuit hydraulic connections have been made, assemble the collector sensor bulb
(Scol) on the bulb-holder provided on the collector, and make the electrical connection on the
connector block of sensors J3, terminals 17 and 18 (see “Connection Diagram”). The collector sensor
"Scol" is supplied with the solar collectors, in the accessory box.
For the solar circuit to function properly, it is essential to start it up correctly, carefully following the
instructions given in the points on this subject in the “Start-up” section of this manual. These
sections provide a detailed description of how to correctly fill the circuit, check the seal and adjust
the flow.
The heat transmission in the Evolution Solar HDX boiler solar circuit is made by means of a heatcarrying fluid consisting of a mix of water (70%) and DOMUSA TEKNIK inhibitor liquid (minimum
30%). The DOMUSA TEKNIK inhibitor liquid’s resistance and heat transmission properties make it
suitable for use in solar heating installations. Its main function is to protect the different
components from corrosion, as the installation contains various metals. The Evolution Solar HDX
boiler is supplied pre-loaded with 7.5 litres of inhibitor liquid in the solar circuit of the hot water
tank, which means the optimum proportion of inhibitor liquid is obtained on filling the circuit (see
“Filling the Solar Circuit").
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.
IMPORTANT: Evolution Solar 30 HDX boilers are specifically designed to function with Ø12 mm
diameter tubes for the flow and return connection between the solar collector and
the hot water tank. If you wish to use any other diameter, consult the DOMUSA
TEKNIK customer service department.
9
3.7 Location of the solar collector
The choice of location for the solar collector is very important, as an unsuitable location could mean
a reduction in the efficiency of the solar circuit due to incorrect orientation, shadows being cast on
the solar collector, etc.
To correctly locate the solar collector, the calculation methods and reference tables figuring in the
“Technical Building Code” (CTE, Section HE 4) should be carefully followed. DOMUSA TEKNIK
provides a calculation computer program for installers, which can be ordered through the
website www.DOMUSA TEKNIK.es. However, it is recommended to bear the following indications
in mind when choosing the ideal location:
- Before deciding on the location, the accessibility of the site must be taken into account, both as
regards the installation itself and for maintenance work on the solar collectors.
- The solar collector must face south.
- The solar collector should normally be installed with a slope 5º greater than the latitude of the
location. Any difference from this angle will reduce its efficiency.
- For installations with integrated supports for slate, the tilt must be at least 27º, and for
those with integrated supports for tiles, it must be at least 16º. The solar collector must be
levelled on installation, so that the upper part is horizontal.
- According to the Technical Building Code, losses due to orientation/tilt and shade must not
exceed the following values:
MAXIMUM LOSSES
Case Orientation and tilt Shade Total
General 10% 10% 15%
Overlap 20% 15% 30%
Architectural integration 40% 20% 50%
When installing the solar collector, ensure that no objects cast shadow on it, particularly in winter,
when the sun is lower in the sky. The minimum distance from an obstacle the solar collector can be
installed at depends on the height of the obstacle and the latitude of the site of installation, as
shown in the table below:

3.8 Removal of combustion products
The combustion product exhaustion ducts must be installed by qualified personnel and must
comply with current legislation and standards.
The Evolution Solar HDX boiler is a sealed oil-fired boiler, and the combustion products are
therefore removed through an outlet pipe, with a separate air intake from outside. We recommend
that the position of the outside exhaustion duct is as shown in the figures and in the table below:

(*) Providing the width of the balcony is not over 2000 mm.
(**) If the pipe is made of materials sensitive to the action of the flue gases, this distance should be over 500 mm.
Note: Spanish law also stipulates that the end of the exhaustion duct must be at a distance of at least 400 mm from any air intake
opening, and from the wall.
IMPORTANT: All accessories used for combustion product removal and air intake are to be
those supplied by DOMUSA TEKNIK.

4 REMOVAL OF COMBUSTION PRODUCTS
4.1 ø80 dual duct system for combustion product removal and air intake (type C53)
For this type of boiler, combustion product removal and air intake take place through separate Ø80
mm dual ducts, using the Ø80 dual duct outlet kit, code CGAS000265. Evolution Solar HDX boilers
are equipped with this type of fume removal by default.
The maximum length of piping that can be installed is 12 metres, which is the maximum sum of the
metres of the air intake duct and the metres of the combustion product removal duct. Each 90º
elbow, or each two 45º elbows, will reduce the available length by 1 m. One horizontal metre is the
equivalent of 2 metres.
It is recommended to fit the exhaustion duct in a slightly upwardly-inclined direction, at around 2º 3º, thus preventing any water and condensation from dripping out.

4.2 Changing from dual duct fume removal to coaxial fume removal
The Evolution Solar HDX boiler has a Ø80 dual duct system for combustion product removal and air
intake. If you prefer the combustion products to removed by means of a Ø80/125 coaxial tube, you
may use the Ø80/125 coaxial tube adaptor kit (supplied to order), code CGAS000213 + code
CGAS000222.
Adaptor for coaxial tube 80/125
Code CGAS000213 + CGAS000222
The changeover may be made with two different assembly configurations:
1. Rear outlet: simply remove the combustion air intake from the boiler, unscrewing the three
screws holding it in place, mount the adaptor on the fume outlet towards the rear, and use the
flexible air inlet tube to connect it to the adaptor T.
2. Side or top outlet: the procedure is the same, but for side mounting of the adaptor kit a 90º
Ø80 elbow (code CGAS000147) needs to be fitted before the adaptor at the fume outlet.
The two configurations are shown in the figures below:

5 STARTING-UP THE BOILER
5.1 Prior warnings
Repair and maintenance of the boiler must be carried out by a qualified professional, authorised by
DOMUSA TEKNIK. For optimum functioning and conservation of the boiler, it should be serviced
annually.
Carefully read this instructions manual and keep it in a safe, easily-accessible place.
Before any servicing, disconnect the boiler from the mains and cut off the oil supply. Any
manipulation of the sealed parts of the boiler is prohibited.
DOMUSA TEKNIK will not be liable for any damages caused by failure to follow these instructions.
5.2 Filling the domestic hot water tank
The hot water tanks must be filled before filling the heating circuit. Open the flow of domestic hot
water to the hot water tank, and turn on a hot water tap in the installation. When the tap begins to
run freely, turn it off, as this means the hot water tank is full.
5.3 Filling the heating circuit
To fill the heating circuit installation, open the fill valve
(20)
until a pressure of 1 - 1.5 bars appears
on the “
boiler pressure
” setting on the display. The circuit should be filled slowly and with the
automatic air bleed valve caps
(16)
and
(11)
loose, to let the air out of the installation. The air
should also be bled from the rest of the installation using the air bleed valves provided. When the
installation has been filled, close the fill valve.
Evolution Solar HDX boilers have a pressure sensor
(13)
for controlling the pressure of the
installation. If the installation pressure drops below a minimum of 0.5 bar, the boiler will not switch
on and a low pressure alarm will appear on the display ("AP").
NOTE: Switching on the boiler with no water inside could result in serious damage.
5.4 Start-up
In order for the guarantee to be valid, the boiler must be started up by an official DOMUSA
TEKNIK Technical Assistance Service. Before beginning start-up, the following must be complied
with:
- The boiler must be electrically connected to the mains.
- The installation must be filled with water (the manometer must indicate 1 - 1.5 bar).
- Fuel must be reaching the burner at a pressure of no more than 0.5 bar.
- The solar circuit must be filled up to the level socket.
5.5 Installation delivery
After the initial start-up, the Technical Assistance Service will explain to the user how the boiler
functions, making any observations they consider relevant.
The installer is responsible for clearly explaining to the user the functioning of any control or
regulation device forming part of the installation but not supplied with the boiler.
Evolution Solar HDX
16
5.6 Filling the solar circuit
The Evolution Solar HDX boiler is supplied with the inhibitor liquid required for its correct
functioning. The rest of the solar circuit needs to be filled with tap water to obtain a perfect mix of
heat-carrying fluid and for optimum circuit functioning. The circuit is filled by connecting a hose to
the filling inlet on the solar hot water tank.
To correctly fill the solar circuit, proceed as follows:
- Connect the filling inlet to the water
mains with a hose.
- Connect a hose to the level socket and
lead it to a container.
- Open the level socket valve.
- Turn on the water supply.
- When liquid begins to come out of the
level socket, cut off the water supply to
the filling inlet.
- Close the level socket valve when liquid
stops coming out of it.
If the solar circuit should need to be drained and filled while carrying out maintenance, ensure it is
filled with the correct mix of water and inhibitor liquid, with at least 30% inhibitor liquid
(minimum 15 litres).
IMPORTANT: DOMUSA TEKNIK will only be liable for the correct functioning of the system if it
has been filled with DOMUSA TEKNIK inhibitor liquid.
17
5.7 Solar pump functioning in manual mode
For start-up and maintenance of the solar circuit, the solar circulation pumps need to be switched
on manually. The Evolution Solar HDX boiler allows the solar pumps to be activated using the "HN"
setting on the digital display. To do this, use the MODE touch button to browse to this setting and
the On touch button
(25)
to access it. When you have accessed the setting, use the touch button on
the right of the display
(27)
to change the value, enabling the solar pumps with the following
values selected:
"0" – Automatic functioning mode (default value).
"1" – Solar pump is switched off.
"2" – The solar pump is activated.
"3" – Solar pump speed activated defined " U5" parameter.
When you have selected the desired manual functioning mode, place your finger on the On touch
button again to record the value and exit the "HN" setting. Operating modes 0, 1 and 2 will remain
activated indefinitely, until another operating mode is selected (even if the boiler is switched off
and switched on again). However, for safety reasons, manual modes 3 and 4 will only remain active
while they are selected, and the "HN" setting cannot be exited until another mode is selected (if the
boiler is switched off at this point, it will return to automatic operating mode when it is switched on
again).
IMPORTANT: The solar circuit must only be serviced and installed by sufficiently qualified
personnel, in accordance with current national and local installation and safety
legislation and standards.
5.8 Starting up the solar pump with timer
For correct system start-up, the solar circuit is equipped with 2 circulation pumps, one of which has
a timer (BST). When the system has started up, after ensuring that the heat-carrying liquid is flowing
through the whole circuit and when the flow is stabilised (15 minutes by default), the electronic
control switches off the pump with a timer, as one pump is sufficient to maintain the flow, thus
optimising the electricity consumption of the solar circuit.
To change the switch-off time for the pump with a timer, use the MODE touch button to browse to
the "
Switch-off time for solar pump with timer
" display option. When this option is displayed, touch
the "+/-" symbols on the touch button on the right of the display
(27)
to select the desired time. The
switch-off time can be adjusted between OFF and 5 and 30 minutes. To disable the switch-off
function for the pump with a timer, select "
OFF
" for the pump to remain continuously switched on
while there is solar energy.
IMPORTANT: The solar circuit must only be serviced and installed by sufficiently qualified
personnel, in accordance with current national and local installation and safety
legislation and standards.
5.9 Checking the solar circuit seal
For the solar circuit to function correctly, it is very important to ensure it is correctly sealed. To do
this, switch on the two solar pumps in manual mode by selecting “2” on the “
HN
” setting on the
digital display (see “
Solar pump functioning in manual mode
”).
After 15 minutes have elapsed and with the pumps still switched on, check there are no leaks
anywhere in the solar circuit. Make sure no siphons have been created in the installation, as this
would prevent correct drainback of the solar circuit.
Evolution Solar HDX
18
IMPORTANT: Insufficient sealing of the solar circuit and a siphon effect caused by incorrect
layout of the piping can cause serious operating problems.
5.10 Adjusting the solar circuit flow
For the solar circuit to function correctly it is essential to regulate its flow. The Evolution Solar HDX
boiler has a manual adjustment device with a window for viewing the flow, which is supplied totally
open at maximum flow and should be adjusted to 2 l/min. To do this, when the solar circuit has
been filled, carefully proceed as follows:
1 - Select the "HN" setting on the display using the MODE
touch button. When you have selected it, access it
using the On touch button.
2 - Select 2 on the touch button on the right of the display
(27)
. The two pumps will start up.
3 - Let the pumps run for at least 15 minutes, to ensure the
flow has stabilised.
4 - Repeat step 1 to switch off the solar pump with a timer,
selecting 3 on the "HN" setting.
5 - Remove the red wheel from the interlock switch and fit
it to the end of the flow regulator indicator. Turn the
wheel to adjust the flow to 2 l/min, as shown on the
display. When you have adjusted the flow, turn the red
wheel back in its initial position again.
6 - Lastly, return to automatic solar pump functioning
mode, selecting the value 0 on the "HN" setting.
IMPORTANT: The solar circuit flow must be adjusted to 2 l/min. For installations that do not
reach a flow of 2 l/min, it is recommended to leave the flow regulator totally open.

insulation in your home.
23
8 OPERATION
The Evolution Solar HDX boiler is designed to heat a heating installation and provide domestic hot
water by solar collection. Optionally, a second heating circuit, heating circuit 2, may be connected to
the installation to improve its performance.
The boiler also includes a DHW collecting and storage system whereby installation of the solar
collectors supplied with the boiler optimises the use of the solar energy in the collection area, for
economical, environment-friendly domestic hot water production. The solar functioning principle
consists of heating the solar circuit liquid in the solar collectors and then exchanging the heat
absorbed with the domestic hot water in the hot water tank. As an auxiliary source of energy to back
the main source, the oil-fired boiler adds the necessary heat to obtain a suitable domestic hot water
temperature, if the energy collected from the sun is not sufficient.
8.1 Solar circuit functioning
The Evolution Solar HDX boiler is equipped with a circuit, separate from the heating circuit, for the
producing DHW using solar energy. This is called the “Solar Circuit”. This circuit basically consists of
a dual-chamber DHW tank, for exchanging heat with the domestic hot water, two solar circulation
pumps, a flow regulator and one or two solar collectors, for exchanging heat with the sun.
The functioning of the solar circuit is based on the drainback principle, whereby the heat-carrying
liquid in the solar circuit does not completely fill the installation, maintaining the solar collector
empty while there is no demand for solar energy and thus preventing freezing or overheating
problems. When there is a demand for solar energy, the solar pumps start up so that all the air in
the solar collector is conveyed towards the dual chamber of the solar hot water tank. The heatcarrying fluid circulates through the solar collector, collecting the energy provided by the sun and
exchanging it with the domestic hot water stored in the solar hot water tank. When there is no
demand for solar energy, the solar pumps stop and the heat-carrying fluid returns to the dual
chamber of the hot water tank by the force of gravity, and the solar collector drains again
(drainback).

The boiler’s electronic control system manages the automatic functioning of the solar circuit,
switching on the solar circulation pumps when the temperature difference detected is over 6 ºC.
Evolution Solar HDX
24
Also, the “
Maximum solar water tank DHW setpoint temperature
” display option can be used to
limit the maximum desired DHW temperature in the solar hot water tank. When this temperature is
reached, or when the temperature difference between the solar sensor “Scol” and the hot water
tank sensor “Si” is less than 4ºC, the boiler’s electronic control system switches off the solar pumps.
For correct system start-up, the solar circuit is equipped with 2 circulation pumps, one of which has
a timer (BST). When the system has started up, after ensuring that the heat-carrying fluid is flowing
through the entire circuit and the flow is stabilised (15 minutes by default, see “
Starting up the solar
pump with timer
”), the electronic control disconnects the pump with a timer as one pump is
sufficient to maintain the flow, which optimises the solar circuit’s electrical energy consumption.
8.2 Heating Function
In this mode, select the desired boiler setpoint temperature (see "
Selecting the boiler setpoint
temperature
") and the temperature of room thermostat 1 (TA1) or remote control E20 (if the boiler
is equipped with these). The burner and the heating pump of circuit 1 (BC1) will begin to function
until the installation reaches the selected boiler setpoint temperature (or the temperature on room
thermostat, if the unit has one). When the temperature of the installation drops below the selected
boiler temperature, the burner will start up again, running the heating cycle.
If the DHW temperature in the boiler’s integrated back-up hot water tank is lower than the DHW
setpoint temperature selected, the heating function will cut out and priority will be given to
domestic hot water production, starting up the hot water tank feed pump.
The boiler heating function can be totally disabled (
Summer
mode) by selecting "OFF" as the boiler
setpoint value. In this operating mode, only the DHW production function will remain enabled,
providing there is a DHW tank connected to the boiler.
NOTE: When the heating function is disabled, circuit 2 will also be disabled if it is connected.
8.3 Domestic Hot Water production function of tank
In this mode to activate this mode, select the desired DHW setpoint temperature (see "
Selecting the
DHW setpoint temperature
"). The burner will igniteand and the DHW pump. When the tank reaches
the setpoint temperature selected it was ready to heat the heating circuit if it was on.
If you wish to totally disable the boiler’s DHW production function, select the setpoint value "
OFF".
In this case DHW will only be produced by the boiler’s solar heating system.
25
8.4 Heating circuit 2 functioning (Optional)
All the models in the Evolution Solar HDX range of boilers have the option of controlling a second
heating circuit. This requires the installation of a second circulation pump on the boiler. To correctly
install this pump, carefully follow the instructions given in the “Installing heating circuit 2” section
of this manual.
Heating circuit 2 will work with the selected boiler setpoint temperature (see “
Selecting the boiler
setpoint temperature
” ) and the temperature of room thermostat 2 (TA2) (if the boiler has one). The
burner and the heating pump of circuit 2 (BC2) will begin to function until the installation reaches
the selected boiler setpoint temperature (or the temperature on room thermostat 2 (if the unit has
one). When the temperature of the installation drops below the selected boiler temperature, the
burner will start up again, running the heating cycle.
NOTE: When the heating function is disabled, if OFF is selected circuit 2 will also be disabled.
8.5 Functioning with an SRX2/EV Underfloor Heating Kit (Optional)
The Evolution Solar HDX boiler may optionally be supplied fitted with an SRX2/EV underfloor
heating kit (fitted to heating circuit 1). This kit basically consists of a motorised 3-way mixing valve
and an underfloor heating installation flow temperature sensor.
The underfloor heating installation is worked by the electronic boiler control. The installation flow
sensor is used to adjust the temperature, selecting the installation flow setpoint temperature using
the boiler setpoint adjustment touch button on the control panel, between OFF, 0 and 45 ºC (see
“
Selecting the Underfloor Heating flow setpoint temperature
”). In this operating mode, the
electronic control sets the boiler setpoint temperature to 75ºC by default, and the installation flow
temperature can be adjusted to the selected setpoint temperature using the mixing valve.
The boiler setpoint temperature can be changed using the MODE touch button to browse to the
“
boiler setpoint temperature
" display option. When the display shows this option, touch the "+ /-"
symbols to select the desired temperature.
If you wish, the SRX2/EV Underfloor Heating circuit function can be totally disabled, by selecting
"OFF" as the installation flow setpoint temperature.
NOTE: When the Underfloor Heating circuit function is disabled by selecting OFF as the
setpoint temperature, only circuit 1 will be disabled. Circuit 2 will continue to function.

9 ADDITIONAL FUNCTIONS
The Evolution Solar HDX boiler is equipped with an electronic control for efficiently regulating the
automatic functioning of the boiler. It also has the following additional control features:
9.1 Pump anti-block function
This function prevents the boiler circulation pumps from seizing up if they have been out of use for
a long period. This system remains enabled while the boiler is plugged into the mains.
9.2 Anti-frost function
This function protects the boiler from freezing up during cold weather. If the boiler temperature
drops to below 6 ºC, the heating circulation pump will start up. If the boiler temperature continues
to drop and reaches 4 ºC, the burner will start up, heating the installation. When this function has
been activated, it will continue working until the boiler reaches 8 ºC. This system remains on
standby while the boiler is plugged into the mains.
9.3 Telephone relay connection
The Evolution boiler is designed to enable a phone relay to be connected for switching the boiler
on and off. This feature allows the boiler to be switched on and off remotely, from any location, by
means of a phone call. The relay is connected to the boiler via terminal strip J7 (see “Electrical
Connection Diagram”). When the telephone relay contact closes the boiler switches on. When the
contact opens, the boiler switches off and remains in anti-frost protection and pump anti-block
mode.
9.4 Anti-legionella function (optional)
This optional function prevents the bacteria causing legionnaire’s disease from proliferating in the
hot water accumulated in the hot water tank. Every 7 days, the temperature of the water in the hot
water tank is raised to 70 ºC to kill any such bacteria. This function will only be enabled if the boiler
is left switched on.
The boiler is supplied with this function disabled. To enable it, carefully read the "Installation
Instructions" section. We recommend that the operation for enabling this function is carried out by
qualified personnel.
9.5 Boiler pressure sensor function
This function prevents boiler failure caused by a low water level or excess pressure in the boiler. The
pressure is detected by a pressure sensor
(13)
, and its value appears on the control panel display
(see “
Digital display
”). If the pressure drops below 0.5 bar, the electronic control blocks boiler
functioning and triggers the “AP” alarm on the display. If boiler pressure exceeds 2.5 bar, the "HI"
warning will flash on the display to warn of the excess pressure. If this should occur we recommend
calling the nearest Technical Assistance Service, and slightly draining the boiler.
9.6 Room thermostat connection
The boiler has two terminal strips, TA1 and TA2, for connecting room thermostats or room
chronothermostats (J5 and J6, see "
Electrical Connection Diagram
”). This allows the heating mode
for each circuit installed to be switched off according to the room temperature. To suitably connect
them, first remove the bridge joining the terminals of terminal strip TA
1
, and to connect TA2, simply
connect the thermostat to the terminal strip.
Installing a room thermostat will optimise the installation’s performance, adapting the heating to
the requirements of your home and obtaining enhanced comfort. Also, if the thermostat allows the
27
hours of functioning to be programmed (chronothermostat), it can adapt the heating system to the
hours of use of the installation.
9.7 Disconnecting the oil-fired boiler’s back-up energy supply
The Evolution Solar HDX boiler’s electronic control allows the oil-fired boiler’s function as an
auxiliary power source backing the solar energy to be disconnected, so that the only hot water
produced by the boiler will be that obtained from the solar energy of the installation site, with only
the solar circuit functioning. To disconnect the oil-fired boiler’s back-up energy supply, select the
"
OFF
" as the DHW setpoint temperature (see "
Selecting the DHW setpoint temperature of the back-
up hot water tank
").
9.8 Disconnecting the solar circuit
The Evolution Solar HDX boiler’s electronic control enables the solar circuit functioning to be
disconnected, if this should be required for maintenance or start-up. If the solar circuit functioning
is disconnected, the boiler will work as a standard oil-fired storage heating and hot water boiler,
and will not use the solar energy from the site where it is installed.
To disconnect the solar circuit, firstly disconnect the "Si" and "Scol" sensors from the sensor
terminal strip J3 ("Si": terminals 19-21, and "Scol": terminals 17-18), and fit electrical bridges in their
place, shorting the inputs of these sensors (see “Electrical Con
nection Diagram
").
9.9 Keypad block function
This function protects the control panel from being accidentally or erroneously pressed while it is
being cleaned, by children or by unauthorised persons. When this function is enabled, the
electronic control will not react when any of the symbols or touch buttons on the control panel are
pressed.
To lock the keypad, keep your finger on the RESET touch
button for 5 seconds. The word "LOC" will flash on the display
until the control panel is unlocked again.
To unlock the keypad, place your finger on the RESET touch
button again for 5 seconds. The display will then return to its
normal status.
10 E20 REMOTE CONTROL (OPTIONAL)
A remote control (E20) can optionally be supplied together with the Evolution Solar HDX boiler. This
remote control can be used to fully operate the boiler from any room in the home in which it is
installed. The E20 remote control governs the settings of heating circuit 1 and the installation’s
domestic hot water production (where the case may be).
This remote control allows the hours of home comfort to be programmed for heating circuit 1,
adjusting the installation to the particular requirements of the home by measuring the room
temperature and consequently adapting the installation temperature. The remote control can also be
used to adjust the DHW and heating setpoint temperatures at any time, and for viewing the different
boiler operation settings. It also warns of any functioning anomalies affecting the boiler.
The E20 remote control may optionally be connected to an external sensor, for measuring the outside
temperature. When this option is installed, the remote control can adjust the home comfort level
(circuit 1) according to the weather conditions at each particular time, optimising fuel consumption
and heating comfort in the home.
Evolution Solar HDX
28
The E20 remote control takes over the control of the boiler when it is connected to it. The different
selectable boiler temperatures must be modified using the remote control. It is easy to install, only
requiring 2 wires for communication between the boiler and the E20 control. It is connected to the
boiler by connecting the two wires on terminal strip J4 (see “Electrical Connection Diagram”). For
correct installation and functioning, carefully read the instructions enclosed with the remote control.
The following sections contain a general explanation of the E20 remote control’s different operating
modes and options.
10.1 Functioning without an outdoor sensor
Conventional heating installation (direct circuit)
The maximum temperature for heating circuit 1, the scheduled heating times and the desired
room temperatures can be selected on the remote control. The E20 remote control will calculate
the boiler temperature required at each particular time, depending on the temperature of the
room, and it will activate or disable the heating mode of circuit 1 depending on the heating
times and room temperatures programmed.
Heating installation with an SRX2/EV underfloor heating kit (mixed circuit)
If the boiler has an SRX2/EV Underfloor Heating Kit installed on circuit 1, the underfloor heating
circuit is adjusted and controlled from the boiler control panel (see "
Functioning with an
underfloor heating kit
").
The E20 remote control can be used to programme the desired heating times and room
temperatures.
10.2 Functioning with an external sensor (Optional)
If the E20 remote control is fitted with an outdoor temperature sensor, it can calculate the heating
temperature of heating circuit 1 according to the outside weather conditions at each particular
time, with optimum adjustment of the heating installation conditions for improved comfort in the
home and energy savings.
Conventional heating installation (direct circuit)
The maximum temperature, an operating curve for heating circuit 1 (see instructions enclosed
with the E20 remote control) and the desired heating times and room temperatures can all be
selected on the remote control. The E20 remote control calculates the required boiler
temperature at each particular time, depending on the temperature inside the home and the
outside weather conditions, in accordance with the operating curve selected (setting
HEATSLOPE 1 on the E20), switching the heating on and off in accordance with the heating times
and the room temperatures programmed.
Heating installation with an SRX2/EV underfloor heating kit (mixed circuit)
If the boiler has an SRX2/EV underfloor heating kit installed on circuit 1 and the control of this kit
is activated on the E20 remote control using the HEATSLOPE 2 setting (see instructions enclosed
with the E20 remote control), the adjustment and control of the underfloor heating circuit flow
temperature will be performed by the remote control. The E20 will calculate the required flow
temperature at each particular time, depending on the temperature inside the home and the
outside weather conditions, in accordance with the operating curve selected (the HEATSLOPE 2
setting on the E20 remote control). For mixed underfloor heating circuits, we recommend
selecting operating curves of less than 0.8.
The boiler setpoint temperature will be fixed at 75ºC and can be changed using the boiler
control panel. This setpoint temperature can be changed by using the MODE touch button to
browse to the “
boiler setpoint temperature
" display option. When the display shows this option,
touch the "+ /-" symbols to select the desired temperature.
29
The E20 remote control can also be used to select the maximum flow temperature for heating
circuit 1 and to programme the desired heating times and room temperature. The E20 remote
control will switch the heating function of this circuit on and off in accordance with the heating
times and room temperatures programmed.
NOTE: For mixed underfloor heating circuits, we recommend selecting a maximum flow
temperature NO HIGHER THAN 45 ºC, to protect the underfloor heating installation from
overheating.
10.3 DHW mode functioning
The E20 remote control can be used to select up to two DHW temperatures and the desired DHW
production times. The E20 remote control regulates the DHW tank temperature at each particular
time, and enables or disables the DHW function according to the times scheduled.
The E20 remote control also has an option for enabling a function to protect against legionella
bacteria (see instructions enclosed with the E20 remote control).
10.4 Telephone relay function
The E20 remote control is designed for connection to an external telephone relay. If a telephone
relay is connected to the E20 remote control, the heating mode of heating circuit 1 and the DHW
mode can be switched on and off from anywhere in the world, simply by making a telephone call
(see instructions enclosed with the E20 remote control).
11 SHUTTING DOWN THE BOILER
To switch off the boiler, place your finger on the power touch button
(25)
for 1 second. In Off mode,
while the boiler is plugged into the mains and connected to the fuel installation, its heating and DHW
functions will be switched off but the anti-frost protection and pump anti-block functions will remain
activated.
To shut down the boiler functioning completely, unplug it from the mains and cut off the fuel supply.
12 DRAINING THE BOILER
The water is drained from the boiler by opening the air drain valve
(1)
inside the boiler (on the lower
right hand side on opening the door). Connect a flexible tube to this valve and run it to a drain. After
draining the boiler, close the valve again and remove the flexible tube.
13 DRAINING THE SOLAR CIRCUIT
If you need to drain the solar circuit, connect a hose to the solar accumulator drain valve
(2)
and run
the hose to a suitable container (minimum capacity 19 litres), so that the heat-carrying fluid can be
reused if necessary. Open the drain valve and the level valve. After draining the circuit, close the shutoff valves and disconnect the hoses.

14 SAFETY CUT-OUTS
The boiler’s electronic control system may activate the following safety cut-outs to stop the boiler
functioning. When one of these safety cut-outs occurs, the boiler will stop functioning, a cut-out code
will flash on the display and the red alarm warning pilot light will flash on the control panel.
If any of the safety cut-outs described below should occur repeatedly, switch off the boiler and
call your nearest official technical assistance service.
14.1 Temperature safety cut-out
When this cut-out occurs, the alarm code “EAt” (temperature
alarm) will begin to flash on the digital display
(19)
. The burner
will switch off and stop heating the installation.
This occurs when the boiler exceeds a temperature of 110 ºC.
To unblock it, wait until the boiler drops to below 100ºC and press the button on the safety
thermostat, located inside the boiler on the underside of the electrical box, after first having
removed the button cover.
14.2 Burner cut-out
When this cut-out occurs, the alarm code “EAQ” (burner alarm)
will begin to flash on the digital display
(19)
. The burner will
switch off and stop heating the installation.
This occurs as a result of an anomaly in the burner
(18)
or in the
fuel installation. To unblock it, press the illuminated button that lights up on the burner.
14.3 Low pressure cut-out
When this cut-out occurs, the alarm code “EAP” (pressure
alarm) will begin to flash on the digital display
(19)
. The burner
and the boiler circulation pumps will switch off, cutting off the
heating and water flow to the installation.
This occurs when the boiler pressure drops to below 0.5 bar,
preventing the boiler from functioning when the water is drained from the installation, due to
either leakage or maintenance operations. To unlock it, fill the installation again until a pressure of 1
- 1.5 bar appears on the “
boiler pressure
” setting on the display
(19)
.

15 BOILER MAINTENANCE
To maintain the boiler in perfect working order, a yearly overhaul should be performed by DOMUSA
TEKNIK’s authorised personnel.
Cleaning the boiler
To keep the boiler in perfect working order, we recommend cleaning the boiler chamber,
exhaustion ducts and condenser on a yearly basis. A cleaning brush of a suitable size for cleaning
the inside of the exhaustion ducts is supplied with the boiler for this purpose. This brush is located
at the rear of the boiler, beside the condenser.
The combustion chamber and exhaustion ducts should not be cleaned using chemical products or
hard steel brushes. After any cleaning operation has been carried out, it is important to run several
ignition cycles to check all the elements are functioning correctly.
For correct cleaning, the following recommendations should be carefully observed:
Cleaning the boiler body
- Open and remove the outer door of the boiler.
- Remove the burner
(21)
by unscrewing the fixing nut on the top of the burner.
- Remove the combustion chamber door and the exhaustion duct cover, unscrewing the six
fixing nuts beside them.
- Clean the exhaustion ducts on the cast iron body, using the cleaning brush supplied with the
boiler.
- Clean the boiler combustion chamber. We recommend using a soft brush for scraping the
combustion chamber surfaces, and a blower to remove scale.
- After cleaning, replace the combustion chamber door, the exhaustion duct cover, the burner
and the outer door of the boiler.
Cleaning the condenser
- Remove the rear extension on the sides of the boiler to access the condenser on the rear of the
boiler body.
- Open the top cover of the condenser
(1)
to access its exhaustion ducts. To open this cover,
firstly release the two side closures
(7)
, turn the locking plate
(2)
anti-clockwise and pull the
cover upwards to remove it.
- Remove the fume deflectors
(6)
inside the fume outlets.
- Clean the exhaustion ducts using the cleaning brush supplied with the boiler. Scale could fall
out of the lower condenser cover and come out of the condensation drain, and it is therefore
recommendable to pour water into the top of the condenser, for more effective cleaning. This
water will be automatically discharged through the condensation drain.
- To clean the outer part of the condenser cylinder, remove the three screws
(3)
and then remove
the metal ring
(4).
Take out the seal
(5)
and use the brush to clean it. Then put the components
back in place again and replace and tighten the three screws and the metal ring.
- If the lower condenser cover
(9)
needs cleaning, remove the side cover of the boiler to access it.
Firstly remove the bracket (8) holding it in place and pull on it to open it. Then pull the lower
cover down to open and clean it.
- After cleaning, replace the fume deflectors, the top condenser cover and the top outer cover of
the boiler. Then put the cleaning brush back inside the boiler.
Evolution Solar HDX

- The condensation siphon should be cleaned once a year. To do this, remove it and wash it in
soapy water. Replace the siphon after cleaning.

Anti-frost protection
The Evolution Solar HDX boiler has a function for preventing frost damage to the installation. This
will function as long as the appliance remains plugged into the mains. Despite this function, and
particularly in areas with very cold weather, we recommend taking precautions in order to prevent
damage to the boiler. It is advisable to add anti-freeze to the water in the heating circuit. If the
boiler is to be out of use for long periods of time, we recommend draining all the water and leaving
it empty.
Boiler water characteristics
In areas with water hardness of over 25-30ºF, treated water must be used in the heating installation
to avoid any scale deposits on the boiler.
It should be noted that even a few millimetres of scale will greatly reduce the boiler’s heat
conductivity, causing a major drop in performance.
Treated water must be used in the heating circuit in the following cases:
- Very large circuits (containing a large amount of water).
- Frequent filling of the installation.
If repeated partial or total draining of the installation is necessary, we recommend filling it with
treated water.
Heat-carrying solar fluid
The boiler’s solar circuit uses a heat-carrying fluid, which is a mix of water (70%) and inhibitor liquid
(30%). This optimises its functioning and helps it remain in perfect working order.
You should check that the heat-carrying fluid in the solar circuit is in good condition. Check that the
proportions of the mix of water and inhibitor liquid are correct (70/30).
The heat-carrying fluid needs to be renewed every 3 years, with a minimum concentration of 30%
of inhibitor liquid (minimum 15 litres).
33
16 CIRCULATION PUMP FLOW CURVES
The following graphs may obtain hidromotriz pressure available at the facility off the boiler,
considering the pressure loss of the boiler and the performance curves of the pump.
16.1 Characteristic heating pump
16.2 Regulation pump heating
To regulate the speed of the circulation pump BC1 by navigating to
the "UB" parameter and touching on the touch button
(28)
to access
it touch MODE button. Once inside the setting, using the jog dial on
the right side of the display
(24)
the value is changed. After selecting
the desired speed, to touch the touch button to record the value and
exit the parameter "UB".
ATTENTION: Any interference in the operation and installation of the heating circuit must be done
by suitably qualified personnel, always respecting current legislation and installation
and safety standards, both national and local level.

22 BURNER.
22.1 Assembly
Fix the burner support to the boiler, then fix the burner to the support. This will allow the correct tilt
of the flame tube towards the combustion chamber. Fit the intake and return tubes, inserting the
oil filter in the intake tube.
22.2 Burner start-up
The "Domestic" burner is equipped with a self-extracting pump to enable fuel intake from a tank
installed at a lower level than the burner, providing the pressure difference measured with the
vacuum gauge at the pump does not exceed 0.4 bar (30 cmHg).
Ensure there is fuel in the tank, that the oil valves are open and that voltage is reaching the burner.
Turn on the master switch. Unscrew the air bleed screw (manometer point). Then, when the valve
opens, remove the photocell sensor and move it towards a light source until the oil comes out.
Disconnect the burner and screw the bleed screw back in.
22.3 Adjusting the combustion conditions
As each particular installation has a different combustion circuit, it is essential to adjust the
combustion conditions of each boiler. In order for the guarantee to be valid, the burner must be
adjusted by an official DOMUSA TEKNIK Technical Assistance Service.
Observe the flame. If there is insufficient combustion air, it will be dark in colour and will produce
smoke, rapidly obstructing the flue outlet.
On the contrary, if there is an excess of combustion air, the flame will be whitish or bluish-white in
colour. This will reduce the performance of the boiler and it will fail to comply with anti-pollution
standards, and the excess air may also hinder the ignition process.
The flame should be orange in colour.
If the shape of the boiler makes it difficult or impossible to observe the flame, the combustion air
flow can be regulated by observing the smoke coming out of the flue. If the smoke is dark in colour,
more air will need to be provided to the burner, or if it is a very whitish colour, the air in the burner
will need to be decreased until no smoke at all is observed.
If you have a device for determining the composition of the combustion gases, this will be the best
guide for flame adjustment. If not, simply follow the above indications.
To adjust the air and burner line conditions, carefully follow the instructions given below.
43
Primary air adjustment
To adjust the primary combustion air,
turn the screw using a 6 mm. Allen key,
as shown in the diagram. Turn it
clockwise to increase the airflow, and
anticlockwise to decrease it.
Combustion line adjustment
To adjust the combustion line, loosen the combustion line blocking screw "BL". Turn the line
regulator "RL" clockwise to increase the airflow and anticlockwise to decrease it. After adjustment,
tighten the combustion line blocking screw "BL".

24 FAILURES
This section provides a list of the most common burner and boiler failures.
Burner error code
We have already mentioned that the burner is equipped with a cut-out system, indicated by the reset
button light. It may cut out accidentally, and in this case the steady red light on this button will come
on. You may unblock it by pressing the button for approx. 1 second. When the burner is blocked and
the steady red light is on, visual failure diagnosis may be activated, in accordance with the error code
table. To enter visual failure diagnosis mode, hold down the reset button for at least three seconds.
