alarm handler shows fan frequency is alarming. However, the fan frequency
on the main control panel looks OK, which is 72~73HZ. But the problem is
that the Heater is 0.01w. Previous TO also reported same problem. Going
to increase JT Valve, however Step size in JT valve is 0.0, and cannot
not be changed. (Once changing, it will get back to 0.0 automatically).
Good news is everything recover to normal automatically after one minute.
