to external connections must be 0.5 mm² up to 50 m, for
example EKKX, LiYY or equivalent.
ELECTRICAL CONNECTION VERSIONS F1345
F1345 has different electrical connection versions depending
on when the heat pump was manufactured. To check which

ignation "2.0" visible above the right hand side of the termin-
al block as illustrated.
CONNECTING COMMUNICATION
This accessory contains a circuit board (AA28) that must
be connected directly to the main product's input board.

stalled, the subsequent boards must be connected in series
with the previous board.
Use cable type LiYY, EKKX or similar with a cable area of at
least 0.5 mm².
