The FE7 remote control enables you to adjust the set room temper-
ature for heating circuit 1 or heating circuit 2 by ± 5 °C in automatic
mode only. You can also change the operating mode. Connect the
remote control to terminals Fernb.1 and Fernb.3 at terminal block
X2 and to the earth block for low voltage X26 of the appliance.

The FEK remote control enables you to change the set room tem-
perature for heating circuit 1 or heating circuit 2 by ± 5 °C as well
as the operating mode. Connect the remote control to terminals
H, L, and + at terminal block X2 of the appliance.
Also observe the FEK operating instructions.
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.
Also observe the operating instructions for the Uponor DEM
WP module.
12.8 Internet Service Gateway ISG
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.
The ISG power supply is not made via the heat pump.
Also observe the ISG operating instructions.
