21.1 Condenser with Inverter or Eci Fans–Analog Output Setting
This configuration is used when all fans of the condensing group are ECI fans or driven by one
inverter or a chopped phase driver.
The capacity used by the inverter is proportional to the delivery pressure value inside the
regulation band (SETF-Pb/2÷ SETF+Pb/2.
21.1.1 Condenser fan configurations and Parameters
Parameter
Description
Action
oA(i) = inF
Set 1 relay for inverter
One relay is used to enable the action of the
inverter.
AoC = tEn
Analog output setting
Set the output as 0-10V
AoF = InF
Analog output function
Set the output to drive ECI or inverter fan
AOM =0
Minimum value for analog
output
The minimum voltage is 0V.
NOTE: verify on the inverter of ECI fan of
chopped phase driver that with this input a
proper output is supplied to the fan.
AOt = 5
Time of analog output at max
after the start
To start the fan the controller supplies 10V
output for 5s, then starts standard regulation
MPM = 100
Maximum % variation per
minute
The analog output takes 1 min to move from
the min to the maximum
