In window Jf09 it is possible to set the regulation range of the fans in cooling and
heating mode
In windows Jf11-13 it is possible to set threshold and differential for override at
maximum speed in cooling and heating mode, in addition to the voltage to be
supplied in override conditions (except with polynomial algorithm).
FNR – Force Noise Reduction
III.1.6.2
If provided, the FNR option makes it possible to dynamically edit the ventilation
settings. Different settings are changed depending on whether function FNR1 or
FNR2 are on.
Furthermore, with FNR2 enabled, the high pressure alarm prevention threshold is
also modified (see paragraph III.1.8).III.1.8

EEO – EER Optimizer
III.1.6.3
If the EEO – EER optimizer option is included, it is possible to enable the
optimisation function of power input through fans modulation and measuring the
dissipated power.
The function is activated with high pressure exceeding the set threshold, after a
standby time with respect to switching on the compressors on each circuit. With
function on, fan modulation is slightly changed at regular intervals, inverting the
variation (in acceleration or slowdown) if the power input measurement is worse
than that read with the previous speed. The optimisation function is able to act
within a maximum deviation with resect to the normal modulation ramp defined in
window Jf04.

EEO function is able to act
Anti-snow protection
In the event of heavy snowing, the fans might get clogged by solidified snow and,
when started up, are unable to turn properly. It is therefore possible to set forced
ventilation at low speed in case of outdoor temperature lower than a threshold.

III.1.6.4 Water-water condensing control
The condensing control makes it possible to regulate the amount of water of the
disposal unit used (typically well water) and is carried out by modulating opening
of a 2-way valve or by driving an inverter pump with a 0-10V signal based on
condensing pressure (if enabled it is possible to also perform evaporation control).
