4 Product description
The CompTrol Interface is an expansion module for the X/Y remote control bus of indoor units
from Mitsubishi Heavy Industries. It connects the X/Y remote control bus to the control unit of the
building services management system (BMS).
The CompTrol Interface is integrated in the X/Y remote control bus as an additional user. It acts
as an additional wired remote control. The CompTrol Interface can control up to 16 indoor units.
Depending on which program is selected, the CompTrol Interface reads an analog signal (4 to 20
mA, 0 to 20 mA, 0 to 5
V DC
, or 0 to 10
V DC
) at analog input X3-S and transmits the value to the
indoor unit in the form of a setpoint (see “4.4.1 Analog input X3” on page 19). Various functions
are available, see “5 Functions of the CompTrol Interface expansion module” on page 23 .
