Note
■
If Smart Grid is enabled (
"Enable Smart Grid 7E80"
set to
"1"
), both inputs DE2 and DE3
cannot
be
used for signals "External demand" or "External
blocking".
■
The power-OFF function is integral to Smart Grid.
Therefore do
not
connect the power-OFF signal to
terminals X3.6 and X3.7. Do
not
remove jumper.

Note
■
If Smart Grid is connected to the two digital inputs on
main PCB (
"Enable Smart Grid 7E80"
set to
"4"
),
the external hook-up for the heating/cooling circuits
must not be switched on (
"Remote control 2003"
set to
"2"
). Otherwise the Smart Grid will not be
active.
■
The power-OFF function is integral to Smart Grid. In
this case, therefore, the power-OFF signal must
not
be connected to connections X3.6 and X3.7.
