3.3 - Electrical control connections
The Heat Pump is pre-equipped with a non-polarised, 2-core sheathed cable (communication bus). This 10m cable is supplied with, and
already connected to, the Heat Pump. It must be connected to the Pilot.
If the connection needed is longer than 10m replace this cable with a 20m cable which is available to order (Ref. 751005).
• On the Pilot, cut the bus link to the right length :
LOOPS ARE FORBIDDEN.
• On the Pilot, cleanly remove 10cm of the shielding to prevent any short circuits.
• Connect the two wires (stripped to 10mm) to the Pilot.
•
IMPORTANT
, DO NOT connect the bus link shielding to the ground of the Pilot.
