INFORMATION
In case of preferential kWh rate power supply, connect
X11Y to X11YB. The necessity of separate normal kWh
rate power supply to indoor unit (b) X2M/5+6 depends on
the type of preferential kWh rate power supply.
Separate connection to the indoor unit is required:
▪ if preferential kWh rate power supply is interrupted
when active, OR
▪ if no power consumption of the indoor unit is allowed at
the preferential kWh rate power supply when active.
INFORMATION
The preferential kWh rate power supply contact is
connected to the same terminals (X5M/9+10) as the safety
thermostat. Thus, the system can have EITHER
preferential kWh rate power supply OR a safety
thermostat.

To connect the backup heater power
supply
WARNING
The backup heater MUST have a dedicated power supply
and MUST be protected by the safety devices required by
the applicable legislation.
CAUTION
To guarantee the unit is completely earthed, always
connect the backup heater power supply and the earth
cable.
The backup heater capacity can vary, depending on the indoor unit
model. Make sure that the power supply is in accordance with the
backup heater capacity, as listed in the table below.

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
.
