Functions of the CompTrol Interface expansion module
5 Functions of the CompTrol Interface expansion module
5.1 Functions of analog input X3
Analog input X3-S is only evaluated if a signal is applied to digital input X2b-D4 .
5.1.1 Temperature setpoint definition via analog signal
When an analog signal is applied to analog input X3-S , a temperature setpoint between 18 °C
and 30 °C is specified for the indoor units. The table listing the correlations between analog signal
type and temperature can be found in the relevant program description.
Temperature setpoint definition is possible in the following programs:
– Program 0 and programs 2 to 7.
5.1.2 Direct frequency request via an analog signal
When an analog signal (4 to 20 mA, 0 to 20 mA, 0 to 5
V DC
, or 0 to 10
V DC
) is applied to analog
input X3-S , a frequency setpoint is specified for the compressor in the outdoor unit. The frequency
setpoint for the outdoor unit in question is permanently stored in the CompTrol Interface. The
CompTrol Interface is set to the correct outdoor unit model via DIP switches S1-5 to S1-8 . More
information on setting the outdoor unit model via DIP switches S1-5 to S1-8 can be found in the
description of programs 8, 9, and 10.
Direct frequency request is possible in the following programs:
– Programs 8, 9, and 10.
For a direct frequency request with cascading, the compressor frequencies of two outdoor units
can be adjusted via an analog signal from an external controller. The options “Cascading without
signal overlap” and “Cascading with signal overlap” can be selected via DIP switches.
Direct frequency request with cascading is possible in the following program:
– Program 9.
Direct frequency request with the CompTrol Master is possible in the following program:
– Program 10 (CompTrol Interface V4.0.3 and higher).
Direct frequency request is available with the following unit series from Mitsubishi Heavy
Industries:
●
FDS series,
●
S series.
