Date-specific memory
The date-specific function enables daily, monthly and annual recording of meter readings.
The 2 different versions allow either the total meter readings for specific times, or the values for a
time period (day, month, year) to be established.
The integral mathematics function can, for example, calculate the performance factor of a heat
pump.
Analogue input signal for the value to be saved
Selection: Differential, Value
A wide range of function quantities are available, which are applied
together with their unit and their decimal places.
➢ Differential mode: The differentials of the calculated values between beginning and end of
the day, month and year are saved. This version is suitable, for example, for calculating the
daily, monthly and annual performance factor of a heat pump.
Example: Daily value
➢ Value mode: The calculated values (e.g. meter readings) for the respective point in time
(end of day, end of month, end of year) are recorded.
Example: Daily value
Calculation
With the help of the integral mathematics function, the input variables A - D can be linked
mathematically.
If only one input variable is available, variables B to D remain on value 1 and the operators on
"multiplication". The result of the calculation is therefore identical to input variable A.
The result of the calculation is then saved in accordance with the mode.
