The instructions given in this manual describe the operation and maintenance of DOMOTIC Series DOM-XX, DOM-XX PH and DOM-XX
PLUS Salt Electrolysis Systems. For optimum performance of the DOMOTIC Series Salt Electrolysis Systems, we recommend you to follow
the instructions given below:
1. CHECK THE CONTENTS OF THE PACK: ___________________________________________________________________________
You should find the following elements inside the box:
Power supply.
Electrolysis cell.
pH sensor (only in DOM-XXPH).
EX-ORP sensor (only in DOM-XX PLUS Series).
Calibration solutions pH 7.0 (green) / pH 4.0 (red) / ORP 470 mV (only in DOM-XXPH and DOM-XX PLUS models).
Sensor holder (only in DOM-XX PH and DOM-XX PLUS models).
CEE22 (M) connector for dosage pump (only in DOM-XX PH and DOM-XX PLUS models).
Operation Manual.
2. GENERAL FEATURES: _________________________________________________________________________________________
When DOMOTIC Series Salt Electrolysis System is installed, a quantity of salt must be dissolved into the swimming pool water. This salty
water then passes through the electrolysis cell that is located in the plant room. The DOMOTIC Series Salt Electrolysis System consists of
two elements: an electrolysis cell and a power supply. The electrolysis cell contains a quantity of titanium plates (electrodes) and when a
weak electrical current is passed through the plates inside the electrolysis cell, there is chlorine production.
Maintaining a level of chlorine in swimming pool water keeps the water sanitised and healthy to swim in. The DOMOTIC Series Salt
Electrolysis System will manufacture chlorine whenever the pool circulation system (pump and filter) is operational.
The power supply is provided with various safety devices, which are activated in case of irregular operation of the system, as well as a
microprocessor driven control system.
The DOMOTIC Series Salt Electrolysis Systems have an automatic cleaning system that avoids scale formation on the electrodes. Moreover,
DOMOTIC-PH Series Systems include a built-in pH controller, as well as an additional ORP controller in the case of DOMOTIC-PLUS Series
models.
3. SAFETY WARNINGS AND RECOMMENDATIONS: ___________________________________________________________________
The equipment should be assembled and handled by truly qualified people.
Current electrical and accident prevention regulations should be followed.
Under no circumstances will the manufacturer be held responsible for the assembly, installation or start-up, nor any handling or
fitting of components unless they are carried out on its premises.
The DOMOTIC Series Salt Electrolysis Systems operate at 230VAC, 50/60 Hz. Do not attempt to alter the system to operate at a
different voltage.
Check that all the electrical connectors are well tightened to avoid false contacts and their consequent overheating.
Before installing or replacing any component, disconnect the equipment from the mains, and use exclusively spare parts supplied
by IDEGIS.
Taking into account the fact that the equipment produces heat, it must be installed in places with sufficient ventilation. Fan
openings should be kept free of any element that could obstruct them. The equipment should not be installed near flammable
materials.
The DOMOTIC Series Salt Electrolysis Systems have an IP24 protection degree. They should never be installed in places
susceptible to flooding.

4. INSTALLATION: _______________________________________________________________________________________________
4.1. Installation of the power supply
Always install the POWER SUPPLY of the DOMOTIC Series system VERTICALLY on a solid and rigid surface (wall) as shown in the
recommended installation diagram (Figs. 1,2). In order to guarantee a good state of conservation, the POWER SUPPLY should be installed
in a well-ventilated dry place. Due to IP degree of the POWER SUPPLY the DOMOTIC Series system should not be installed outdoors. The
POWER SUPPLY should be installed a bit distant from the electrolysis cell so that it cannot accidentally suffer water splashes.
Beware of corrosive atmosphere formation due to pH decreasing solutions (specially, those ones based on hydrochloric acid "HCl"). Do not
install the DOMOTIC Series system near to any stores of these chemicals. We strongly recommend the use of chemicals based on sodium
bisulphate or diluted sulphuric acid. Power supply must be connected to the electrical control box of the pool, so that the pump and the
DOMOTIC Series System are turned on (and off) simultaneously.
4.2. Installation of the electrolysis cell
The electrolysis cell is made of a transparent polymer in whose interior the electrodes are placed. The electrolysis cell must be always
installed indoors and after the pool filter, and after any other equipment that may be present (heat pumps, control systems, etc.).
The installation of the cell should allow easy access to the installed electrodes by the user. It is highly recommended to install the electrolysis
cell VERTICALLY, in a place of the pipe that can be easily isolated from the rest of the installation by two valves, so that the tasks of
maintenance can be carried out with no need of partial or total draining of the swimming pool.
Where the cell is installed on a by-pass (recommended option), a valve to regulate the flow must be introduced. Prior to installation, please
consider the following commentaries:
Fig. 3 Fig. 4 Fig. 5
1. Flow direction marked in the cell
must be respected. Recirculation
system must guarantee the minimum
flow stated in the Table of Technical
Specifications for each model (see
Section 9).
2. The system flow detector activates if
there is not recirculation (flow) of water
through the cell or if flow is very low. If
electrolysis gases are not properly
removed through the electrolysis cell,
the generated gas bubble electrically
isolates the auxiliary electrode
(electronic detection). Therefore, when
locating the electrodes in the cell, the
level sensor (auxiliary electrode) will
have to be located in the higher area of
the cell. The safest orientation is shown
in the recommended installation
diagram.
3. WARNING: if the in-out valves of the
electrolysis cell are closed
simultaneously, the flow detector (gas
detector) will not work correctly, with
the consequent risk of cell breakdown.
Although this situation is extremely
unusual, it can be easily avoided once
the equipment has been installed, by
locking at opened position the return
valve to the swimming pool, so it
cannot accidentally be manipulated.

6
Other configurations would only be acceptable in the case that they allow for detection of gas bubbles when water flow through the cell is too
low.
The electrodes must be inserted in the electrolysis cell, fitting the central electrode through the guides located at the top and bottom of the
cell.
Fig 10
4.3. Electrical connection of the electrolysis cell
Make the interconnection between the electrolysis cell and the power supply according to the following scheme. Due to relatively high current
intensity circulating do not modify or cut either the length or section of the supplied cables without making a previous consultation to an
authorized IDEGIS distributor. The cable connecting the electrolysis cell and the power supply should never exceed the maximum length
recommended in this Manual: DOM-12 (6 A), 7.5 m.; DOM-24 (12 A), 4.0 m.; DOM-32 (16 A), 3.0 m; DOM-42 (7 A), 16.0 m.

4.4. Installation of the pH / ORP sensors (only in DOM-XX PH and DOM-XX PLUS).
1. Insert the pH / ORP sensors into their corresponding places of the holder (Fig. 12)
2. To that purpose, loosen the connection screws and insert the sensor into the holder.
3. The sensors must be installed in the holder so that it is guaranteed that the sensors located in their ends are always submerged in
the water circulating through the pipe.
4. Always install the pH / ORP sensors vertically or with a maximum inclination of 40o(Fig. 13).
Fig. 12 Fig. 13
4.5. Installation of the optional external flow detector (not included with the equipment)
1. Install the saddle supplied in a section of the pipe at the entrance to the electrolysis cell. It should always be installed in a
horizontal position relative to the ground (see Fig. 14-1).
2. Install the flow detector (flow switch) vertically in the saddle (Fig. 14-1).
3. There is an arrow on the head of the flow detector. Make sure that this arrow is parallel to the pipe shaft and pointing in the
direction that the water flows (Fig. 14-2).
4. Do not install the flow detector near magnetic objects. They could affect the operation of the magnetic device it contains and
reduce its reliability.
Fig. 14-1 Fig. 14-2

4.6. Installation of the removable control terminal
In the DOMOTIC series systems it is possible to establish a remote control of the electrolysis salt system installed in the swimming pool by
means of a control wall terminal installation. The interconnection between the power supply and the control terminal can be executed through
a 6-conductor signal cable connected to the respective connectors in power and visualization cards. The cable length will be determined by
the customer’s requirements but must be always lower than 40 meters. The terminal is 10,5 Vac auto-supplied by the communication bus, so
it doesn’t need any additional supply.
The wall terminal doesn’t require any special maintenance procedure, with the exception of these maintenance recommendations:
oUse a slightly moisten cloth to clean it.
oDon’t use aggressive cleaning products (bleach, sprays, solvents, alcohol, etc.)
The remote control is designed to be installed on a rigid wall. Its IP-65 degree allows the outdoor installation. Nevertheless, it’s recommended
not to expose the terminal to the solar rays. In order to install the remote control, follow the instructions shown below:
1. Remove the power supply cover by unscrewing the fixation screw (Fig. 11-1) and sliding upwards and outwards (Fig. 11-2). Then
turn the cover to the left (Fig. 11-3) and disconnect the communications bus (A) from power and visualization cards (Fig. 11-4).
2. Unscrewing its four fixation screws (Fig. 11-5).
3. Assemble the control terminal (Fig. 11-6).
OPTION A: installation using the original IDEGIS cable ref. DOM-020-XX (XX indicates the cable length in meters).
OPTION B: installation using a standard 6-conductor signal cable (each conductor must have a 0,22 mm2minimum cross section).
In both cases the maximum possible length is 40 meters. Nevertheless, using an Unshielded Twisted Pair (UTP) (Category 5e
unshielded) allows interconnection distances until 60 meters.
4. For this purpose, put the new communications cable (A) through the cable gland situated in the terminal base and connect it in
either one of the two connectors of the visualization card (CN1A, CN2A) [OPTION A], or in the connector CN-5 [OPTION B].
Combine the visualization frontal and the terminal base using the four screws supplied.
5. Put the free end of the communications cable through the AUX 2 hole situated on the power supply base (Figs. 11-7, 11-8) and
connect it in the connector CN10A/CN11A [OPTION A] or in the connector CN-20 [OPTION B] in the power card (Fig. 11-9).
Replace the cover in the power supply (Fig. 11-7).
6. Fix the wall fixation (see section 8) in the chosen installation point and hang the control terminal on it.

Besides basic operations, the DOMOTIC Series electrolysis system has three inputs for voltage-free contacts, enabling the connection of
additional external controls. They are located on connector [CN7] of the power card (Fig. 17).
Fig. 17
The logic associated to these three inputs can be programmed during the system configuration process (see point 5.2)
o[FS] OPTIONAL EXTERNAL FLOW DETECTOR CONTROL (not included with the equipment): input for potential-free
contact. When the contact connected to this input is open (external flow detector at rest), and the [FS] is configured as [FS1c],
the electrolysis system switches off due to the flow alarm. Connect the external flow detector wiring to the respective input
[FS], placed in the [CN7] connector, on the unit’s power card.
Fig. 18
o[co] AUTOMATIC COVER CONTROL: input for potential-free contact. Depending on the status of the contact connected to
it on the automatic cover’s electric panel, this input enables you to programme a reduction of the equipment’s output current to
a percentage of its nominal value.
Fig. 19

13
o[or] ORP / RESIDUAL CHLORINE control (unavailable in DOMOTIC-XX PLUS models): input for potential-free contact. This
input can be used to install an external controller of the electrolysis system (ORP, RESIDUAL CHLORINE, PHOTOMETER,
etc.). To that purpose connect two cables from the potential-free contact, placed in the external controller, to the
corresponding input [or] placed in the system’s control card.
Fig. 20
4.9. Start-up
1. Check that the filter is 100% clean, and ensure that the swimming pool and the installation do not contain copper, iron or algae. Ensure
that any heating equipment on the pool is suitable for use in salt water.
2. Ensure that the swimming pool water is balanced, because like that the chlorine produced is used more efficiently and effectively, and
ensures that the life of the electrodes is prolonged. Water should be maintained within the parameters shown below.
a) pH must be in the range 7.2-7.6
b) Total alkalinity must be in the range 60-120 ppm
3. Although the DOMOTIC Series system can operate within a salinity range of 4 – 6 g/l, the minimum recommended level of salt, 5 g/l, should
be maintained by adding 5 kg per m3of water if the water did not previously contain salt. Always use common salt (sodium chloride), without
additives like iodides, that is “apt for human consumption”. Never add the salt through the electrolysis cell. Add it directly to the swimming
pool or into the balance tank.
4. When adding the salt, and in case the swimming pool is going to be used immediately, carry out a treatment with chlorine. An initial dose of
2 g/m3of trichloroisocyanuric acid may be added.
5. Prior to starting up the salt chlorinator, disconnect the power supply to the salt chlorinator and run the pump for 24 hours to ensure that the
salt is completely dissolved.
6. Next, reconnect the power supply and turn on the salt chlorinator, locating the production level so that free chlorine concentration stays
within the recommended range (0.5 – 1.5 ppm).
NOTE: in order to establish the free chlorine level you will need to use a test kit.
7. In outdoor swimming pools it is advisable to maintain a level of 25-30 g/m3of chlorine stabiliser (cyanuric acid) in the pool. A level of 75
ppm should be never exceeded. This will help to stop the chlorine that is in the water from being destroyed by the sun.

5. OPERATION:__________________________________________________________________________________________________
5.1. System on stand-by
The system goes into “STAND-BY” when the “”[1] key is pressed until the “0%” light blinks. When this occurs, there is no production in the
electrolysis cell.
Fig. 21
5.2. System configuration
The DOMOTIC Series system can be reconfigured through a menu accessed from the control panel. The system has to be switched off, as
described in point 5.1, in order to access this menu. Once the system has been switched off, press the “”[1] key for a few seconds until the
system information screen [11] displays “CONF”. To enable selection of each menu option, keep the “SALT TEST” [9] key pressed for
approximately 1 second. Select the desired parameter using the “”[1] / “” [14] keys and validate by pressing the “SALT TEST” [9] key for
one second again (see Fig. 23). The configuration process enables you to establish the following operative parameters:

5.3. Production level selection
To select the desired production level, press the “”[1] / “” [14] keys until the production level light blinks. The system information screen
[11] will display the value of the production scale light [4]. The system will set its production to the desired level after a few seconds.
Fig. 24
In normal conditions, the production value [4] should be the same as the programmed value. However, if the salt level in the water is outside
the permitted range (“HIGH SALT” [7] or “LOW SALT” [6] alarms on), or there is a problem in the electrolysis cell (“ELECTRODES” [13] alarm
on), the production value [4] could be lower than the programmed and displayed value [11].
WINTER Mode:during periods of low water temperature select a production level [1] in the 50-60% range.
5.4. Salinity test
The DOMOTIC Series systems have an integrated system to detect the salinity level of pool water. To run the test, press the “SALT TEST” [9]
key. During the test, the production light will range from 20%-80% of the salinity scale [5], alternately displaying “SALT” and “TEST” on the
system information screen [11]. Once the test is completed, the light will blink for a few seconds on the scale [5] on the detected salinity value
(see Fig. 25). The equipment will return to normal operating mode after a few seconds.
Fig. 25
The system might show lower than actual salt levels if the temperature falls beneath 20C (68 °F).

17
5.5. Integrated pH controller (DOM-XXPH)
The integrated pH / ORP controller is supplied with a default factory calibration and programmed with the following parameters:
SETPOINT pH=”7.2” / ORP=”700 mV”
IMPORTANT: In order to have a correct regulation of the pH value, the Total Alkalinity of the pool water must be maintained in the range
60–120 ppm CaCO3. Use a pool water test kit to check the Total Alkalinity and adjust manually if necessary.
5.5.1. CONNECTION OF THE PH / ORP SENSORS (models DOM-XX PH and DOM-XX PLUS)
Connect the pH / ORP sensor provided with the unit to the corresponding BNC connectors located in the unit’s base (Fig. 26).
5.5.2. CONNECTION OF THE DOSAGE PUMP
The DOMOTIC Series systems (DOM-XXPH and DOM-XX PLUS) have a connector on their base for connecting a dosage pump to control
the pH of the water in the pool. The dosage pump can be connected through the CEE22 connector supplied for that purpose with the
equipment (Fig. 26).
Fig. 26
5.5.3. PH SETPOINT PROGRAMMING
Keep the “SET” [20] key pressed until the screen [18] displays the desired pH value within the 7.0 – 7.8 range. Release after selection.
Fig. 27

18
5.5.4. ORP SETPOINT PROGRAMMING (only in models DOM-XX PLUS)
Keep the “SET” [26] key pressed until the light displays the desired ORP value within the 600 – 850 mV range. Release after
selection.
Fig. 27b
5.5.5. SAFETY STOP CONFIGURATION OF THE DOSAGE PUMP (PUMP-STOP FUNCTION)
The integrated pH controller has a security system (PUMP-STOP FUNCTION) acting on the dosage pump which allows to avoid the following
situations:
Damages caused by the dry operation of pump (depleted pH-minus product).
Over-dosage of pH-minus product (damaged or aged sensor).
PH regulation problems due to high alkalinity in the water (newly filled pool, high carbonate levels).
When the PUMP-STOP FUNCTION is enabled (factory default), the system stops the dosage pump after a programmed time without having
reached the pH setpoint.
Fig. 27c.
The PUMP-STOP FUNCTION is factory set to 60 minutes. To change this value, follow the next procedure.
