Thread-topic: Error with Psychrometric Routine?

I am passing 22.2 C dry bulb and 14.0 C wet bulb to the psychrometric routine (type 33f) and the output is 22.2 C dry bulb, 6. 8 C wet bulb and 0% RH, which is causing an error in the psychrometric routine for a total energy wheel.

The output should be approximately 60% RH.

The humidity ratio is also showing 0.0.

Please advise,

Fred
