2.7.3. EEM ACCESSORY - ENERGY METER
The EEM accessory allows certain unit features, such as those below, to be measured and displayed:
o Power supply voltage and total instantaneous current absorbed by the unit
o Total instantaneous electric power absorbed by the unit
o Instantaneous power factor (cosφ) of the unit
o Electricity consumption (kWh)
If the unit is connected via a serial network to a BMS or external supervisory system, the trends of the measured parameters can be stored and the oper-
ating status of the unit itself checked.
Attenzione: per poter utilizzare l'accessorio EEM, l'unità deve essere alimentata con la tensione 400V-3ph – 50Hz.
2.7.4. FDL ACCESSORY - FORCED DOWNLOAD COMPRESSORS
The FDL accessory (forced reduction of the power consumed by the unit) allows power to be restricted according to the utility requirements by setting, on
a dedicated page, the desired maximum power %.
The function, which can be enabled and configured from the unit display, can activated via a digital signal (potential-free contact), daily time bands or, if
there is a serial network, via Modbus.
In the presence of the EEM accessory, which allows for the instantaneous measurement of the absorbed power, it is possible to set a precise maximum
absorbed power value.

EQRU-EQRHU units with FNR-Q accessory work in super-silenced mode
with the performance and operating limits of the respective EQRUSS-
EQRHUSS. For outdoor air temperatures exceeding the operating limits
(refer to the section of the operating limits for more details), the units lose
silence and guarantee the functions of the respective EQRU-EQRHU.
EQRU-EQRHU units with FNR-Q accessory operate in super-silenced mode
with performance and operating limits (see operating limits section for
further details) of the respective EQRUSS-EQRHUSS thus guaranteeing
quiet running throughout their whole work range.
