Safety

Intended use

The Internet Service Gateway (ISG) is an information and communication interface between your heat pump/integral ventilation unit and your home network.

This appliance is intended for domestic use. It can be used safely by untrained persons. The appliance can also be used in a non-domestic environment, e.g. in a small business, as long as it is used in the same way.

Any other use beyond that described shall be deemed inappropriate. Observation of these instructions and of instructions for any accessories used is also part of the correct use of this appliance.

Appliance compatibility

Note

Your system’s date of manufacture must meet the minimum requirements. Otherwise, your system is not designed for operation with the ISG.

• Note the manufacturing date of your system.

Note

The ISG is only compatible with systems whose heat pump manager (WPM) is equipped with the minimum software versions.

• If in doubt, consult our service department

Note

The Modbus TCP/IP software is installed on the ISG at the factory and can be used with compatible devices.
