Hazard warning: Before performing any work on the controller
or the components connected to it, disconnect the controller
from the power supply as instructed. The outlets are also in
an inactive state under mains voltage.
We would also ask you to install the systems supplied by us
according to the installation instructions. Our warranty shall be
rendered void in the event of damage caused to the systems or to
the heating system or building due to violation of these instructions.
Refurbishments or alterations are only permitted after consultation
with the manufacturer. The manufacturer accepts no liability for
any damage resulting from improper use of the units.

accordance with the German Infection Protection Act, in particular
Article 37 of the Drinking Water Ordinance, DIN 1988, DIN 50930
Part 6, DIN 2000, DIN 2001 and DIN 18381 as well as VDI 6003

• During installation, make sure that the open ends of the pipes
are protected against dirt during work breaks.
• The safety equipment of the drinking water delivery installation
must comply with DIN EN 806-2 and DIN 1988-200 or the
comparable national regulations or standards.

• Hot drinking water pipes must be provided with the prescribed
thermal insulation in accordance with EneV and DIN 1988-200.
• The drinking water pipes must be insulated in accordance
with recognised engineering practices.
• The cold water pipes should not be insulated together with
the heating pipes. Thermal separation or, preferably, spatial
separation is required.

4 l Uponor Combi Port BASE XU l Installation manual
In the case of installations in the public sector (multi family homes,
hotels, retirement homes, hospitals, sports halls, etc.) care must be
taken to ensure that the heated drinking water temperature does not
fall below 60°C and the circulating water re-entering the unit reaches
a minimum temperature of 55°C. This requires accurate calculation
and precise adjustment of the circulating line.
The system is maintained in compliance with DIN EN 806-5 or, outside
Germany, in accordance with national regulations or standards.
Use-related wear of wearing parts, such as pumps, built-in valves
(moving parts, PM valves, etc.) are not considered as defects.
We recommend a maintenance cycle especially for example for the
built-in heat exchanger (test, dirt, sludge, lime), PM valve (functional

5 Please instruct the system users properly and provide them with
these installation and operating instructions together with the
inventory documents.
Please check that the units are complete. Any screws that
are loosened during transport should be retightened.

Never remove individual parts of the unit (or any other built-in
components) while the system is still under pressure (risk of injury).
If you have any questions about correct operation or function,
please contact your supplier. Of course you are also welcome
to contact us directly anytime.

observed for the electrical wiring (e. g. DIN VDE 0100-540).
Please connect the station as follow:
1 Connect Combi Port XU electrically (see wiring diagram)
2 Connect individual room controller: please follow to the
corresponding instruction Smatrix or Flexiboard
3 Coding of actuator: please follow to the corresponding instruction
Smatrix or Flexiboard.
4 Establish equipotential bonding by using a copper equipotential
bonding conductor (cross-section at least 6 mm2). Connect the
earthling clamp to a suitable equipotential bonding rail in the
building.
Warning!
Danger to life due to electric current!
Contact with live parts may cause fatalities.
Disconnect the distribution station from the power supply
and secure it against being switched back on.
Test for absence of voltage.
The pump may only be connected by a qualified
electricain.

Caution!
Property damage due to improper commissioning!
Improper commissioning can lead to damage to property.
• Only an authorised specialist can carry out commissioning.

heat interface unit. If necessary tighten the connections When tighte-
ning connections, always lock the opposite side.
Vent the accumulated air in the heat interface unit by opening the
venting screw. Observe the system operating pressure.
To commission the heat interface unit, follow these steps:
1 Testing the device prior to commissioning
2 Filling
3 Flushing
4 Venting
5 Checking settings
6 Completing the acceptance protocol (commissioning)
7 Handing over the device to the operator
Testing the device prior to commissioning
Prior to commissioning, you must verify proper installation through
visual inspection as follows:
• Check that any dirt accumulated during installation and the dust
on the unit have been removed properly.
• Check the seals on all pipes and device connections.
• Optional: Check that the electrical connections have been made
correctly, that the polarity of the mains connection is correct and
that grounding is assured.
,I\RX¿QGDQLQVWDOODWLRQHUURUGXULQJYLVXDOLQVSHFWLRQ\RXPXVW
temporarily stop commissioning and rectify the error.
At the end of each line, you must perform a line vent. This prevents
the units from drawing in air, which can cause interference on
the units.
To optimally vent the heat exchanger, this must be carried out during
WW dispensing.

in accordance with the setpoint value (hot water temperature). This
keeps the return temperature in the system low, providing scalding
protection. Every thermostat needs a response time (<3 seconds)
before it regulates exactly.

To change the default setting, follow these steps:
1 Remove the thermostatic tip from the valve.
• Please note: Make sure not to bend or break the capillary line.
• Using a welding wire, slide out the locking tabs next to the
adjustment number on the left and right in the direction of
the union nut. If the valve tip is only restricted in an upward
direction (valve can be closed), then you only need to
remove one locking tab.
2 Remove the top part of the valve head.
• Lift out the internal anchor using a strong round object.
3 Adjust the hand wheel.
• Line up the white marking on the toothed sleeve with the
white alignment mark underneath the lettering.
• Gently turn the hand wheel to setting 5.
• Turn the hand wheel from setting 5 to the desired setting
Adjustment example: for 50°C set to scale value 4.
4 Block the setting.
• Insert the clips behind the number set on the hand wheel.
• Reinstall the hand wheel to the set value so that the hand
wheel is blocked with the new setting.
5 Install the thermostatic tip.
• Screw the valve tip onto the valve The standard setting
is changed.
