Connection extension for ISM7e digital Wolf control accessories
Module description
The ISM7e interface module enables remote access to components of the FGB/FGB-K gas condensing boiler via networks and
the internet.
The connection is made via eBus.
The ISM7e interface module enables the user to display current states, readings and parameters of the gas condensing boiler
and to input various settings. The ISM7e is designed for installation outside a gas condensing boiler and is supplied with a
casing that is also suitable for wall mounting. The ISM7e interface module can be integrated into an existing network either with
a network cable (LAN) or wirelessly (WLAN).
For secure communication over the internet, the ISM7e interface module is linked to the existing DSL router, through which a
secure connection to the Wolf portal server is established.
The system is operated over the internet either by means of the Wolf portal user interface operated via internet browser or with
the "Smartset" smartphone app, which can be downloaded and installed from the appropriate app store.
An internet connection is not required if access to the gas condensing boiler is to be limited to the local home network.
Operation from within the home network occurs either via the "Wolf Smartset" smartphone app or via the "Smartset" Windows
PC application (available to download from the Wolf website: www.wolf-heiztechnik.com).
