12.7 uponor dem Wp module
When an Uponor DEM-WP module is connected, the heating curve
is dynamically optimised for the heat demand of individual rooms.
This involves modifying the preset heating curve by up to 50 %
of its original value.
The Uponor DEM WP module is connected as an alternative to an
FE7 remote control. Operation with both devices is not possible.
Connect the Uponor DEM WP module to terminals Fernb. 1 and
to terminal block X2 of the appliance.

The Internet Service Gateway ISG enables you to operate the heat
pump in your local home network and via the internet when on
the go. Connect the Internet-Service-Gateway to terminals H, L,
and to terminal block X2 of the appliance.
