3 Math channels are required to calculate one RH.

Td = AI1, analog input for dry bulb temperature (PT100)

Tw =AI2, analog input for wet bulb temperature (PT100)

Math1 = Ed = 6.112*EXP((17.502*AI1)/(240.97+AI1))

Math2 = Ew= 6.112*EXP((17.502*AI2)/(240.97+AI2))

Math3=RH= (Math2-(0.66875*(1+0.00115*AI2)*(AI1-AI2))/Math1)*100
