* VI4 and VI5 terminals are best suited for connecting the ARU5 room unit
** Install the terminal only in case of missing L-FAN IN conductor on the boiler electrical harness
Always connect the N and PE wires to the nearest free N and PE terminals
For flue gas sensor and solar panel sensor use the Pt 1000 type (AGF3, VFF00)
For other sensors, use Pt 100 type (KTF20, SF20, AF20)
