ACCESSORIES WITH CIRCUIT BOARD AA5
Accessories that contain circuit board AA5 are connected
to the heat pump terminal block AA3-X4: 13-15. Use
cable type LiYY, EKKX or similar.
If several accessories are to be connected, connect the
first accessory card directly to the heat pump terminal
block. Other accessory boards are connected to the first
in series.
Because there can be different connections for accessor-
ies with circuit boards AA5, you should always read the
instructions in the manual for the accessory that you
are going to install.
