CF 1 Defines the type of unit to control
0 = Air to air unit
1 = Air to water
2 = Water to water
CF 2 Selection of unit working mode
1 = chiller only
2 = heat pump only
3 = chiller with heat pump
CF 3 Enable compressor operation
0 = chiller and heat pump
1 = chiller only
2 = heat pump only
CF 4 Motor-condensing unit
0 = no
1 = yes
Temperature control, dynamic set point and energy saving functions are
automatically disabled when CF04 = 1

Parameter Description
Analogue Inputs
SP 1 Working in temperature or pressure from an analog input
0 - NTC cond. temperature / evap. pressure 4.0.20mA:
The condensation temperature is controlled through the use of an NTC
probe, while a transducer with an input of 4-20 mA must be used to
control the evaporation pressure of the circuits and the pressure of the
pressure probe configured as an auxiliary output
1 - Condensation and evaporation pressure 4.0.20mA:
A transducer with an input of 4-20 mA must be used to control the
condensation or evaporation pressures
2 - NTC cond. temperature / evap. pressure 0..5V:
The condensation temperature is controlled through the use of an NTC
probe, while a ratiometric transducer with an input of 0÷5V must be used
to control the evaporation pressure of the circuits and the pressure of the
pressure probe configured as an auxiliary output
3 - Condensation and evaporation pressure 0..5V:
A ratiometric transducer with an input of 0-5 V must be used to control
the condensation or evaporation pressures
Note:
SP01 will affect some parameters' measurement unit.
