1. Introduction
Dear customer,
Thank you for choosing the Spa Touch Control for remote control
of your HygroMatik steam generator.
The Spa Touch Control is designed for use with the steam ge-
nerators of the HygroMatik HyLine, CompactLine, HeaterLine,
HeaterCompact, Heater Slim and FlexLine series.
The Spa Touch Control is state of the art technology.
In order to be able to operate the Spa Touch Control reliably or to
set it up, please read this manual. Since the units feature diffe-
rent controls, the operating menus differ from each other with
respect to some of the operating steps. In these cases the menu
descriptions relate to the unit series in a dedicated way.
Please use the Spa Touch Control only when it is in perfect con-
dition and only for the purpose intended.
Should you have any queries please contact your specialist
dealer.
For queries and ordering spare parts please always state type of
unit and serial number.
1.1 Intended use
The Spa Touch Control is a display and operating panel for con-
trol of the operating functions of a HygroMatik steam generator.
The unit is designed for moisture-proof wall installation with fixed
control cable. Use inside the steam cabin is permissible if the
installation manual is stringently complied with regarding the
sealing. Nonetheless we do recommend that installation be out-
side the steam cabin
For test purposes the unit is capable for temporary portable use
on a HygroMatik steam generator. Since no strain relief for the
control cable is provided the permanent portable use of the dis-
play and operating panel is not permitted.
1.2 Protection class
When correctly installed the front of the assembly has the pro-
tection class IP 65. The rear protection class is determined by
the construction provided by the customer. The rear protection
class in as-supplied condition i.e. with no additional measures is
IP00.
1.3 Safety instructions
For the running and operation of the Spa Touch Control no spe-
cial safety notes apply. Nevertheless all safety notes applicable
to each respective unit (steam generator) the operation of which
the Spa Touch Control is used for are to be observed.
If the steam bath operation is ceased for a longer period of time,
it is recommended that the steam generator is switched off so
Please note

SPA
Page 6
that no unintended unit start may occur caused by the Spa
Touch Control. If it is intended that the dead leg flushing feature
(if implemented) remains active during this period of time, the
safety interlock sytem must be interrupted instead while the
steam generator itself remains in the „on“ state.
1.4 Typographic distinction
» With this double chevron operating steps are identified
which are absolutely necessary for retrieving a function
or carrying out a setting.
1.5 Definitions
In this operating manual differentiation is made between the
user and the operator of the steam bath facility.
User (hereinafter called "user")
The user is a person who wants to "utilize" the steam bath facil-
ity. User operation of the steam bath is limited to the essentials.
The operating functions of the Spa Touch Control accessible to
the user are depicted in the "User level".
Operator
The operator is the entity which has the technical responsibility
for the facility. The operator can determine the functions of the
steam bath facility in full and define which operating functions
are to be made accessible to the user.
The operating functions of the Spa Touch Control available to
the operator are depicted in the "Operator level". The user level
is of course available to the operator as well.

SPA
Page 9
3. Mechanical setup
The Spa Touch Control consists of the monitor assembly, the
installation well with 2 attachment bores for the monitor assem-
bly with rear welded M4 nuts and the faceplate.
The monitor assembly is designed as a sandwich construction.
The actual touchscreen is connected through a frame and com-
bined with the circuit board at the rear to form a single compact
unit. The circuit board carries the combined system plug for the
12V AC power supply and the RS485 2-wire bus.
After fitting the installation well (see section "Wall installation")
the monitor assembly is attached to the flange of the installation
well with the two M4 countersunk bolts. The finish at the front is
provided by the black anodized aluminium faceplate which is
attached to the frame over the whole area or with the aid of the
four adhesive spots (see section "Wall fitting").

4. Wall installation
4.1 Installation principle
The Spa Touch Control is designed for flush mounted installa-
tion. To protect the assembly an installation well is included
which subject to the conditions provided by the customer is to be
plastered into a solid wall construction or inn the case of a cavity
wall installed in another way. Depending on the judgement of the
implementing company installation in a dry cavity wall can be
made without the installation well. The attachment bores with M4
threads are then to be provided by the customer.
For leading the control cable to the electronic module the cus-
tomer is similarly responsible for finding a suitable method (laid
flush-mounted or in cavity).
4.2 Choice of installation location
The installation of the Spa Touch Control can be made inside or
outside the steam cabin. The installation height above the floor
is to be selected so that easy reading of the screen is possible
for the kind of usage envisaged (sitting or standing operation).
4.3 Installation steps
» Plaster installation well into wall recess or install by
other method.
» Lead Cat 5 control cable into well and connect to 20 cm
adapter cable via RJ45 socket or directly to the elec-
tronic module (see section "Electrical connection").
» Place electronic module in the installation well and
attach it to the installation well with the two countersunk
bolts.
» Remove protective film from the 4 adhesive spots.
» Place face cover onto the adhesive spots and press on.
Alternatively the face cover can be glued on by the
application of silicone joint material to the complete sur-
face.
» Draw a silicone joint around the face cover to seal to
the wall.
For the adhesive spots 3MTMVHBTM adhesive tape item
no. "4932" is used. Refer to the relevant data from the manufac-
turer for processing information.
Please note

5. Electrical connection
5.1 Connection principle (Spa Touch Control -
side)
For connecting the Spa Touch Control to the steam generator a
Cat 5 control cable is required to be laid by the customer and
which is utilized for the 12V AC supply as well as the RS485 2-
wire bus. Max. cable length is 50 m.
For connection a 20 cm long adapter cable is supplied which
allows extension of the permanent Cat 5 control cable via the
RJ45 socket also supplied, provided the former is complete with
RJ45 plug.
Alternatively the Cat 5 control cable can be connected directly to
the Spa Touch Control. For this purpose the 4-pin system plug of
the adapter cable is to used. Since the plug uses spring-type ter-
minals, non-destructive dismantling of the adapter cable is pos-
sible.

5.2 Connection to steam generator
5.2.1 On steam generators of the HyLine, Compact-
Line, HeaterLine, HeaterCompact and FlexLine
series:
For connection of the Spa Touch Control to such a HygroMatik
steam generator a connection kit is required (see Section "Over-
view" last paragraph). One component part of this kit is an RJ45
socket in the form of a feedthrough housing (see adjacent illus-
tration).
The Cat 5 cable from the Spa Touch Control is inserted into this
socket.
If the permanent cable is to be directly connected to the steam
generator an RJ45 socket is to be fitted to its end. The core col-
ours for pin allocation correspond with those of the above chart.
The permanent cable can also be completed by the customer
with a flush or surface-mounted RJ45 socket. The connection of
the steam generator can then be made with a commercially
available Cat 5 patch cable in line with normal network engineer-
ing practice.

5.2.2 On steam generators of the HeaterSlim series:
The HeaterSlim steam generator offers the socket marked BU1
on the main board.
The Cat. 5 control cable coming from the Touch Spa Control is
equipped with an RJ45 plug at the end. This is plugged into
socket BU1.
Note: The Cat. 5 control cable and plug can be passed through
one of the M25 cable glands of the steam generator.
If you unscrew the retainer nut of the cable screw connection
you can dismantle the sealing ring inside. It can be replaced with
a slotted sealing ring (in the enclosed accessories package) that
may be bent open for inserting the cable.
5.3 Setting the baud rate for the communica-
tion interface
The communication parameters of the serial interface of almost
all of the HygroMatik steam generators quoted are set ex factory
in a way that the compatibility with the Spa Touch Control is
given (9600 Baud/No parity/1 Stopbit). Exception from the rule is
the FlexLine steam generator that requires a change of parame-
ters (s. below).
Settings for the FlexLine series units
Other than the rest of the steam generators quoted, the FlexLine
units are shipped ex factory with the following parameter set-
tings:
Baudrate: 19200 Baud
Parity: None
Stopbits: 1
For operation with the Spa Touch Control, changing the FlexLine
SPA control baudrate to 9600 Baud is required. To do so, follow
these steps:
» Touch the icon in order to access the settings sub-
menus
» Enter „010“ by means of the virtual keyboard when the
password setting view opens. Confim by touching the
green tick on the upper right side. The first view page of
the main menu opens.
» Use the scroll down arrow on the lower right side to
access the second view page
» Select the communications submenu by touching
the icon. The following screen is displayed:
Sealing ring

SPA
Page 14
» It is only required to make a baudrate setting change.
For that reason, touch the second line in the view and
select „9600“ as the new baudrate (to allow for this,
change the view page by means of the scroll-up key).
Confirm the setting by touching the green tick.
The baudrate is now set to „9600“ for use withe the Spa Touch
Control.

6. Time control of the steam generator with
the aid of Spa Touch Control
With the aid of Spa Touch Control the steam generator can be
run in manual mode, short-term mode (steam release is made
for a fixed period) or timer mode (weekly schedule). In addition
to these, mixed modes are possible. For example through man-
ual intervention, the weekly schedule can be overridden ("man-
ual override").
6.1 Optional operating modes
The operating mode is determined by the operator (see section
"Operation", paragraph "Settings by the operator").
The operating modes only determine the behaviour of the steam
release. Actual steam generation within the scope of the operat-
ing mode selected is determined by control of the steam genera-
tor on the basis of steam bath temperature.
6.1.1 Manual operation
When the user operates the steam button the steam bath opera-
tion is enabled until the release is either withdrawn or the elec-
tronic control system of the steam generator in accordance with
the internal parameter "Limitation of operating time", causes it to
be switched off.
6.1.2 Short-term mode
When the user touches the steam button steam release is made
for a fixed period. During this period no new start is possible;
after expiry however, any number of times.
