4.3 NotesonpositioningtheNordmannOmegaSPADisplays

Please observe the following notes for the correct positioning of the Nordmann Omega SPA Display(s):

– The Nordmann Omega SPA Display(s) must not be installed in hazardous locations and in rooms

where water splashes may occur.

– Do not mount the Nordmann Omega SPA Display(s) inside the steam bath cabin, sauna, bio sauna,

etc..

– If possible mount the Nordmann Omega SPA Display(s) at eye level.

– Do not mount the Nordmann Omega SPA Display(s) in exposed places.

– Do not mount the Nordmann Omega SPA Display(s) on vibrating components.

– Place the Nordmann Omega SPA Display(s) in such a way, that the total length of 50 m of the CAN

BUS cables with which the Nordmann Omega and the Nordmann Omega SPA Display(s) are inter­connected is not exceeded.

4.4 MountingtheNordmannOmegaSPADisplay

CAUTION!

The electronic components of the Nordmann Omega SPA Display are very sensitive to electrostatic
discharge. For all installation work on equipment appropriate measures must be taken to protect these
components against damage caused by electrostatic discharge (ESD protection).

Note: the Nordmann Omega and the Nordmann Omega SPA Display(s) (up to a max. of 8 SPA Displays)
are interconnected via a so-called CAN BUS. Use only a shielded four-wire cable with a cross section
of 0.34 mm
not exceed 50 m.

1. At the desired location, mark mounting opening according to the size of the in-wall housing with the
help of a spirit level, then ream out the mounting opening.
Important: the mounting opening must be reamed out exactly since the decoration cover (broken
line in Fig. 5) overlaps the mounting opening on the right side only 4 mm, on the left side only 9 mm
and on the top and bottom side only 8.5 mm.

2. Knock out the desired cable entry of the in-wall housing and insert the CAN BUS cable (shielded
four-wire cable, 0.34 mm2 per wire) into the in-wall housing. Then, lead the cable through the wall
opening to the steam generator.

3. Insert the in-wall housing into the wall opening, align it with the help of a spirit level, then x it with

the four fastening claws attached to the in-wall housing (only necessary with cavity walls).

Note: in massive walls the in-wall housing must be xed either with the screws and dowels supplied

or by using PU mounting adhesive or mortar.

4. Connect the CAN BUS cable (shielded four-wire cable, 0.34 mm2 per wire) from the Nordmann Ome­ga or from another Nordmann Omega SPA Display to terminals "X2" or "X3" of the control board of
the Nordmann Omega SPA Display according to the gure below. For this purpose, the individual
wires have to be stripped 6 mm and appropriate wire end ferrules have to be crimped. Then, push
individual wires into the correct connection opening of the corresponding terminal until they come
to a stop.
Note: The CAN BUS cable to an additional Nordmann Omega SPA Display is to be connected either
to terminal "X2" or "X3" (see notes in chapter 4.5).

4.4.2 On-wallmounting

1. Using the aluminum on-wall housing as template mark the two xing holes at the desired location,

with the help of a spirit level. Then proceed as follows:

– for the mounting on a stonework wall:

• Drill 2 holes ø6 mm, depth 35 mm.

• Insert the supplied dowels.

• Fix on-wall housing to the wall using the screws supplied, align housing with the help of a
spirit level and fasten den screws.

– for the mounting on a wooden wall:

• Drill 2 holes ø3 mm, depth 35 mm

• Fix on-wall housing to the wall using the countersunk screws supplied, align housing with
the help of a spirit level and fasten den screws.

Note: If the mounting location does not permit bolt mounting (e.g. on a glass wall) the aluminum
on-wall housing can also be glued over its entire surface to the underground.

4.5 ConnectingtheSPADisplaytotheNordmannOmega

Observe and comply with the notes in the installation and operation manual of the Nordmann
Omega steam generator and the local regulation regarding electrical installation when connecting
the Nordmann Omega SPA Display(s) to the Nordmann Omega steam generator!

DANGER!
Danger of electric hazard!

Before connecting the Nordmann Omega SPA Display(s) to the Nordmann Omega steam gen­erator set the steam generator out of operation and disconnect it from the mains!

CAUTION!

The electronic components inside the Nordmann Omega are very sensitive to electrostatic discharge.
When the unit is open for installation work, appropriate measures must be taken to protect these com­ponents against damage caused by electrostatic discharge (ESD protection).

1. Remove front panel of the Nordmann Omega.

2. Insert the CAN BUS cable(s) (shielded four-wire cable, 0.34 mm2 per wire) from the bottom via cable
glands into the control compartment.

3. Cut CAN BUS cable(s) to length. Prepare cable end(s) as shown in Fig. 17 and connect plug(s) to
the CAN BUS cable(s).

5.1 CongurationoftheNordmannOmegaSPADisplay

In principle, the SPA display is ready for operation after the connection and requires no additional con-

guration.

However, if more than one SPA display is used in the system, a unique display address must be assigned
to each connected SPA display.
For each connected SPA display, go to the menu "Menu > Engineering > Communication> Server Set­tings" and assign an individual address to the SPA display via the parameter "Server ID Display".

5.2 OperationoftheNordmannOmegaSPADisplay

For the operation of the Nordmann Omega SPA Display, please refer to the instructions in chapter 6 of
the Nordmann Omega operation manual.
