2. General Safety Guidelines
The following safety advice is designed to protect you from
dangers that can arise from improper handling of devices,
whether intentional or otherwise. A distinction is made be-
tween general advice presented here and specific advice
presented throughout the guidelines.
DANGER for danger to the person
Improper electrical installation of the device can lead to
potentially fatal electric shocks as well as other health
hazards.
CAUTION for danger to property
This symbol indicates dangers that can result in damage to
the components or the function of the control.
NOTE for additional information
This symbol indicates practical advice and tricks of the
trade which will be useful for installing and operating the
control.
2.1 Installer’s Qualifications
●
Setting up and commissioning of the SUNGO SL must
be carried out by a qualified installer.
●
All national and local safety regulations need to be com-
plied with.
●
Please note that in case of a complaint the guarantee is
only valid if correct commissioning has been certified in
a commissioning report.
2.2 Operating Requirements
Application
●
Controlling solar thermal systems through the selection
of applicable control patterns and additional functions
to adapt the control for the required operation of the hy-
draulic system.
●
The control must only be operated in dry rooms.
●
The control can be integrated into the solar circulation
unit or mounted on the wall.
Limitations of use
●
If used in a non-solar thermal application the functionality
of the control has to be checked before commissioning. If
in doubt contact the control service of Wagner & Co.
●
If these operating requirements are not observed any
claims under the warranty will not be accepted.
2.3 Installation and
Operating Information
●
Any installation and wiring work has to be carried out in
an idle state as during operation the voltage on the out-
side of the triacs is 230 V.
●
Mains power must be connected to the control from out-
side the solar station via an external ON/OFF Switch.
This is also required to activate the special functions
menu through switching the mains power ON/OFF.
●
Operating temperatures above 50 °C are not permitted
for the control.
●
LCD display panels are designed in such a way that a
specific reading position is required. When installing the
control, be careful to place the display so that it is at eye
level or slightly higher. This way you can ensure optimal
display contrast.
●
The base of the control is divided into a safety low volt-
age section and a 230 V section by a crosspiece. Make
sure that you do not confuse these sections during the
installation process.
●
The default operating mode is the automatic mode.
Manual operation is used only for functional testing of
the different hydraulic components (pump, 2/3 way
valve). In this operating mode maximum temperatures
or sensor functions are not monitored.
●
Do not operate the system if the control, the wiring or the
connected 230 V mains are visibly damaged.
●
The control is fitted with a mains microfuse.
●
Collectors and hydraulic pipework can get extremely
hot during sunny periods. There is a risk of scalding
when fitting the collector temperature sensor.
3. Installation
3.1 Installation of the case
Opening the case
●
No tools are required to open the control case. The lid
folds over on top of the lower half. You can dislodge and
lift up the lid by pulling gently on the side clips.
●
When fully opened the lid will not move so that you can
take care of mounting and wiring comfortably.
Wall mounting
●
Use the supplied drilling template to drill the fixing holes
for the controller.
●
Mount the control to the wall.
●
Do not overtighten the screws to avoid damage to the
lower part of the housing.
