7 Expansion of the system - CAN bus
The controller is equipped with a high bandwidth CAN bus used to communicate with
the modules. Thanks to the well-known for their reliability, widely used in automotive bus
system is expandable to the highest level.
Use of CAN bus carries several advantages. Gain above all the possibility of using
broadband Lambda oxygen sensor and the using additional of expansion modules
rozszerzeniowych I / O we can install throughout the system:
–
to 16 are heating circuits,
–
2 circuits of hot water,
–
heat storage tank (buffer),
–
solar system (solars).
Socket CAN bus is on the left side of the device. Connecting cable must be connected
according to the following designation.
Cable connection:
L –
line LOW (white)
H –
line HIGH (brown)
GND –
ground (grey)
For connections on the CAN bus should be only used cable
LiYCY 2x0,25.
Only this type of cable gives the proper work of devices. Connections perform in a serial
manner, this represents a figure below.
