Have you checked on the side of the module where the LED is flashing? They usually give the flash codes and what they mean.
Customer: replied 1 year ago.
status steady flashing green not sure if slow or medium flashing slow is standard ops. medium is oil return mode.
com is ***** *****ght with 3 flashes and a pause flashing means flash count when in communication rapid flash with pause means disrupted communication.
y1 and y2 steady green means 1st and 2nd stage compressor requests
it does not specify what ds13 fast flash is
