a.
If required, set a relay to drive the invert (is used to signal to the inverter to start and stop the
regulation), by setting:
oA(i) = inF
inverter for fans
b.
Set the kind of signal of the analog output current (4-20ma) or voltage (0-10V) by the
Analog output setting

“
AoC
”: tEn =
0÷10V output;
cUr =
4-20mA output
c.
Set the function of the analog output:
AoF = InF
d.
Set the time of the analog output at max after start up EI: Aot = 3s
e.
Set the max % variation per min (MP)
f.
At last set also the percentage of analog output in case of probe failure
:
(0 ÷ 100%)

21.2 Analog output
“free”
This setting is used to link the analog output 1 to a temperature probe. The analog output will take
values proportional to the temperatures detected by the probe P3 or P4, according to the setting.

Description
Action
AoC = tEn
Analog output setting
Set the output as 0-10V
AoF = FrE
Analog output function
Set the output to drive for instance a de-
superheater
AOP = P3
Reference probe for the
analog output 1 (used only if
AOP=FrE)
It’s possible to set only P3 or P4 probes.
P3 must be set as temperature probe:
P3C = nt10 (NTC 10K) or nt86 (NTC 86K)
LAO = 20

value
associated to minimum value
of analog output AOM.
It’s the start scale of the analog output
UAO = 40
Temperature
value
associated to the maximum
value of analog output (10V)
It’s the end scale of the analog output
AOM =0
Minimum value for analog
output
The minimum voltage is 0V.
