The intercard bus (pLan) is connected to Climatic™ on the J11 connector of board BM50.
A star connection is not recommended, for an optimum operation it is advised to connect a maximum of two cables per unit.
Connection must be carried out by the following cable:
- Cable length up to 300m: AWG22 (0.34 mm ²), 2 pairs crossed with screen.
- Cable length up to 500m: LiYCY-P (0.34 mm ²), 2 pairs with general shield.
The cable length should not exceed 500m.
For a better electromagnetic protection, Lennox recommends the use of LiYCY-P cable
