6.3 Installing components for the energy supply
company lockout function
With the energy supply company lockout function, the heat
generation from the heat pump can be switched off tempor-
arily by the energy supply company. The unit can be shut
down in two ways:
1. The signal for the shutdown is fed to connection S21
for the indoor unit.
2. The signal for the shutdown is fed to a partition that is
installed on-site in the meter/fuse box.
▶
If the energy supply company lockout function is
provided, install and wire additional components in the
building's meter/fuse box.
▶
To do this, follow the wiring diagram in the appendix of
the installation instructions for the indoor unit.

2. Strip the outer sheathing from the electrical wire. In
doing so, ensure that the insulation on the individual
conductors is not damaged.
3. To avoid short circuits resulting from loose individual
wires, fit conductor end sleeves on the stripped ends of
the conductors.
