Worked today on a number of ceiling cassettes from Mitsu Heavy industries

2 x Model no FDTA 251 indoors

Everything seems to be working ok but noticed that the wall controller display goes from the setpoint temp, set fan speed, louver position etc to show the display of 0.0hz then it goes back to the normal setting display.
The controller display changes about every 10secounds.

Is this normal for this range of Mitsu units
