Electrical equipment complying with EN/IEC 61000-3-12
(European/International Technical Standard setting the
limits for harmonic currents produced by equipment
connected to public low-voltage systems with input
current >16A and ≤75A per phase).
(c)
This equipment complies with EN/IEC61000‑3‑11
(European/International Technical Standard setting the
limits for voltage changes, voltage fluctuations and
flicker in public low-voltage supply systems for
equipment with rated current ≤75A) provided that the
system impedance Z
sys
is less than or equal to Z
max
at
the interface point between the user's supply and the
public system. It is the responsibility of the installer or
user of the equipment to ensure, by consultation with the
distribution network operator if necessary, that the
equipment is connected only to a supply with a system
impedance Z
sys
less than or equal to Z
max
.

5.2.3 To connect the shut-off valve
INFORMATION
Shut-off valve usage example. In case of one LWT zone,
and a combination of underfloor heating and heat pump
convectors, install a shut-off valve before the underfloor
heating to prevent condensation on the floor during cooling
operation. For more information, see the installer reference
guide.
