Hello all,
I've received this error message several times and can't figure out
which input needs to be revised - any help would be great.
**WARNING***************************************************************
*******
In AHU-0-27_ConsSprayRmMUA (MASTER), the return humidity
for a coil exit T of 47.4 is 0.0065
Your setpoint is 0.0005, which may not be held.
***ERROR****************************************************************
*******
In AHU-0-27_ConsSprayRmMUA (MASTER), cooling coil leaving
temperature must
be at least 6F higher than entering water temp.

The 1st warning message is because you have a maximum humidity setpoint
set so the discharge air temperature is being set down to deliver
dehumidification.
The 2nd error message is because the coil leaving air temperature (which
is the cool set T less the temperature pick up across the fan)is not more
than 6F above your chilled water return water temperature. Solutions:
increase your minimum supply air temperature, decrease the fan pick-up
temperature, select the fan as blowthrough or select motor out of the
airstream.
Thanks so much, increasing the SAT worked perfectly.
