Important note:
• Max. distance between controller and display is
3 m over CAN RJ.
• CANbus requires termination in both ends of the cable
by a 120 Ohm resistor to ensure reliable communication.
• On EKE 1C and MMI, the termination must be included
by shorting CAN R and CAN H with a wire.
• No external power supply for MMIGRS2 is needed while
using CAN RJ connector.
Connecting external MMIGRS2 display
MMIGRS2 display can be used to set up EKE 1C. The display
can be used not only for setting up the necessary
parameters, but also as an external display during
operation to show important parameters, e.g. degree of
opening of valve, superheat, etc.
