ƒ= (A-B)*C /........
The calculator allows for converting input values to output values applying your
own formulas. This allows for sophisticated calculations. Two independent
calculator blocks are available.
 Switch on or off aggregates via current heating or cooling output.
 Temperature difference calculation (several input signals possible).
 The calculated value can be provided to other devices at modulating output Y
(DC 0...10 V).
 User-defined formulas can be entered in addition to standard formula (A-B)*C.
 The following mathematical functions are available for calculation:
 Basic operations: Add (+), Subtract (-), Multiply (*), Divide (/).
 Exponentiation n^x.
 Root function n^u, with u = 0.5.
 You can enter three integer and three floating point constants when using
constants in the formula.
 The calculated result may only be used as indicator for switching purposes and
cannot be used for billing purposes.
 Measuring accuracy and sensor placement are prerequisites for the quality of
the calculation.
