Danfoss MMIGRS2 display
Connecting external MMIGRS2 display
MMIGRS2 display can be used to set up EKE 1A. 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.
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.
• External power for MMIGRS2 is not needed while using
CAN RJ connector.
