Product description
4.4.4 X/Y remote control bus X1
X1-X
and
X1-Y
are the connection terminals for the X/Y remote control bus. This bus enables
communication between the remote control, indoor unit, and CompTrol Interface.
The X/Y remote control bus is designed as a power bus with reverse polarity protection, and sup
-
plies the CompTrol Interface with the required operating voltage (see
electrical supply” on page 18).
4.4.5 Bus connections X2 and X4
X2
and
X4
are the bus connectors of the CompTrol Interface. Via this bus, the CompTrol Master
and a maximum of five CompTrol Interfaces can communicate with one another (see CompTrol
Interface Technical Manual). Bus connections
X2
and
X4
form a serial I
2
C data bus.
4.4.6 External electrical supply X5
X5-(+)
and
X5-(-)
are the connection terminals for the external electrical supply. Terminal
X5
does
not have reverse polarity protection. This type of electrical supply is required if the CompTrol
Interface is connected to a CompTrol Master via terminals
X2
and
X4
(see
face electrical supply” on page 18).
4.5 DIP switch S1
DIP switch
S1
is used to select the program, and also to set the installed outdoor unit model in
programs 8 and 9.
Note

-
tings only reliably become effective after a system restart. An exception here are DIP switches
S2-7
and
S2-8
, which govern the behavior of the 7-segment display. These DIP switches for
display behavior can also be set during ongoing operation.
●
When reading the current DIP switch positions, bear in mind the horizontal installation posi
-
tion of the CompTrol Interface! The
ON
switch setting is the one closest to the center of the
expansion module.
