Ratio control The control is always based on variable a.
The maths module forms the ratio of the measurements a and b (a/b) and pro-
vides the setpoint for the controller. The ratio of the measured values a and b
can be called up and displayed via the functions “Maths 1” or “Maths 2”.
The required ratio a/b is programmed in the setpoint input as setpoint (ratio
setpoint).
Humidity
control
The humidity controller receives the process value from a psychrometric hu-
midity probe through the mathematical linkage of wet bulb and dry bulb tem-
peratures.
Variable a - dry bulb temperature
Variable b - wet bulb temperature
