Accessories with circuit board AA9
Accessories that contain the circuit board AA9 are con-
nected to the heat pump's terminal block X4:9-12 on
the input board AA3. Use cable type LiYY, EKKX or
equivalent.
Because there can be different connections for accessor-
ies with circuit boards AA9, you should always read the
instructions in the manual for the accessory that you are
going to install.
