The arithmetic operation is performed according to the following formula:
Function (( A Operator 1 B) Operator 2 (C Operator 3 D))
➢ The first field Function can remain empty, in which case it has no effect on the arithmetic
operation. In this field, a function can be selected which will be applied to the result of the
arithmetic calculation that follows:
o Absolute value abs
o Square root sqrt
o Trigonometric functions sin, cos, tan
o Inverse trigonometric functions arcsin, arccos, arctan
o Hyperbolic functions sinh, cosh, tanh
o Exponential function e
x
exp
o Natural and common logarithms ln and log
➢ The fields marked Operator 1 - 3 are for selecting the arithmetic operation::
o Addition +
o Subtraction –
o Multiplication x
o Division :
o Modulo % (remainder from a division)
o Exponentiation ˄
➢ The brackets must be observed in accordance with mathematical rules.
➢ In the "differential" version, these mathematical calculations therefore allow the daily,
monthly and annual performance factors to be calculated by dividing the heat amount
(thermal energy) by electrical energy and stored on a daily, monthly and annual basis.
