2.4 Safety instructions: warning and danger symbols
The following symbols and notices are provided in appropriate places throughout this
document to designate the safety instructions.
2.4.1 DANGER - Death/serious irreversible injury
Indicates an extremely hazardous situation which will result in death or serious
irreversible injury, if the safety instruction is not followed.
Example:
Electrocution through hazardous voltage will lead to death or serious injury!
• Disconnect the unit from the power supply and ensure the power cannot be
switched back on.
• Ensure the unit is voltage-free and isolated, earth and short circuit the unit,
cover or shield off neighboring live components.
2.4.2 WARNING – Environmental or material damage
Indicates actions that can result in damage to equipment or property.
Examples:
Environmental Damage!
Heavily contaminated filters can have a negative impact on production processes.
Depending on the filtered-out materials, contaminated filters are therefore
classified as hazardous waste and must be properly disposed of according to the
prevailing guidelines and laws.
Damage to the unit!
If dampers are abruptly shut during unit operation, the unit can be damaged
beyond repair as a result of negative pressure or overpressure.

2.6 Safety-conscious work procedures
When working within range of mains voltage:
Electrocution through hazardous voltage will lead to death or serious injury!
• Disconnect the unit from the power supply and ensure the power cannot be
switched back on.
• Ensure the unit is voltage-free and isolated, earth and short circuit the unit,
cover or shield off neighboring live components.
For all kinds of work:
Risk of electrostatic discharge!
While carrying out adjustment work on the ISYteq control panel, make sure that
you discharge yourself statically before manipulating PC boards and installing
electrical components.
• Observe all assembly instructions for the ISYteq control panels.
• Fluctuations and imbalances in the supply voltage may not exceed the tolerance
limits specified in the technical data, otherwise functional failures and limit states
cannot be excluded.

The ISYteq controller is a microprocessor-based, programmable electronic controller,
featuring a multitasking operating system, compatible with the FläktGroup controls
family of devices, which includes programmable controllers, user terminals,
gateways, communication devices and remote management devices.
These devices represent a powerful control system that can be easily interfaced with
most Building Management Systems (BMS) available on the market.
ISYteq has been developed to provide solutions for several applications in air-
conditioning, refrigeration and HVAC/R in general.
ISYteq controllers can be connected in an Ethernet LAN to other FläktGroup family
controllers.
Each device in the LAN can exchange digital or analog variables with all the others,
based on the application program used.
The built-in web server supports HTML standard.
Other innovative functions include the possibility to display the contents of the pGD1
terminal in the browser, and to display graphs of data recorded by the data logger in
real time.
The Integrated USB peripheral can be used to update the controller application and

3.4 Models of ISYteq Display Panels
3.4.1 ISYteq Touch 2.1
This Touch 2.1 control panel is designed as a compact user interface to the
FläktGroup controllers. Due to its size, it can be integrated into rooms more
inconspicuously. Despite its small size, it is a complete and powerful control panel
that supports almost all functions of FläktGroup controllers.
The user will only see the controls on the display whose functionality is reported by
the controller. Operating elements that are not required are hidden.
Figure 3: Touch 2.1 display with a white frame
3.4.1.1 Space requirements
The control panel is mechanically designed for indoor installation in a standard flush
box (68 mm). If the room temperature is to be measured via the integrated sensor in
the control panel, an installation with a standard surface-mounted device box is more
suitable.
