INTEGRA Metering CALEC ST III User Manual

Introduction
3-140-UM-EN-02
9 / 56
Additional functions
Heat- / cold meters eight tariffs
This option allows the management of up to eight different tariffs
with reference temperature control. The measurement is split into
different registers.
Data backup in the event of a
power failure
In EERPOM >10 years
Adjustable low temperature differ-
ence ΔT cut-off (LFCO)
Function for stopping the energy calculation when the temperature
difference is too low, ΔT LFCO adjustable ΔT = 0-2.99K.
Limit value monitoring
One-sided or two-sided, hysteresis 0 – 10%, action of the output
signal is selectable.
