Offset ∆T
Correction factor for the temperature difference for heat metering
Since the collector temperature and the storage temperature can be used for the heat quantity metering, depending on the sys-
tem, there may be deviations from the displayed collected temperature to the actual previous temperature or the displayed stor-
age temperature to the actual return temperature. This deviation can be corrected with the adjustment value Offset ΔT
Example: displayed collector temperature 40°C, read previous temperature 39°C, displayed storage temperature 30°C, read
return temperature 31° means a setting of -20% (displayed ∆T 10K, actual ∆T 8K => -20% correction value)
Daylight saving time
If this function is activated, the controller automatically changes to winter time or summer time (DST, Daylight Savings Time).
