Defines the type of signal used.
4-20 mA (Def.): analogical signal 4-20mA;
0,5-4,5 V: analogical signal 0,5-4,5 V=.
Defines the type of signal used.
0-10 V (Def.): analog signal 0..10V= , or pwm 100Hz type with variable average value
ampiezza 5..15V.
pwm fv: variable frequency pwm (upon on request).
modbus: Controlled by Master controller on RTU Modbus transmission.
(this parameter is displayed only if “IN.TYPE [IB]” is on pwm fv)
Minimum input frecuency used for the PWM fv input.
Min. 2 kHz Max. MaxPwm Def. 2kHz
(this parameter is displayed only if “IN.TYPE [IB]” is on pwm fv)
Maximum input frecuency used for the PWM fv input.
Min. PWMmin Max. 20kHz Def. 18kHz
Defines the full scale value provided by the probes.
Min. 0 bar Max. 1000 bar Def. 50 bar
Defines the measurement unit visualized in the state menu and in the operating
parameters. Bar (Def.) / Millibar / Pascal / kiloPascal
Caution: numbers won’t be converted.
Adjusting value of the temperature probe connected to input 1.

Defines the second operating cycle (it can be activated with I1 contact).
Direct : first cycle COOL , second cycle COOL;
Reverse(Def. ): first cycle COOL, second cycle HEAT;
[WITH S1 CARD]
Defines the pressure reference based on the following criteria:
Automatic in. (Def.): priority to the signal of the higher probe in the cooling cycle, of
the lower probe in the heating cycle;
Minimum in.: priority to the lower signal of the two probes;
Maximum in.: priority to the higher signal of the two probes;
In.2: probe 2 (disables input 1);
In.1: probe 1 (disables input 2);
