Analogue Inputs
SP 1
Temperature or pressure analogue input working:
0 = Temperature / pressure NTC – 4÷20 mA:
The condensing temperature is controlled by the NTC probe
The control of the circuits evaporating pressure and of the pressure probe
configured as auxiliary output is made by the 4÷20mA input
1 = Pressure control with
4÷20 mA input:
The evaporating and condensing pressures control is made by a 4÷20mA
transducer.
2 =
Temperature / pressure
NTC – 0÷5V:
The condensing temperature is controlled by the NTC probe
The control of the circuits evaporating pressure and of the pressure probe
configured as auxiliary output is made by the 0÷5V input
3 =
Pressure control with 0÷5V input:
The evaporating and condensing pressures control is made by a 0÷5V
transducer.
