DT1
The main control delta (temperature difference).
This setting specifies the condition for activating and
deactivating the collector pump. When the sum of the
∆
1 setting and the tank temperature T2 exceeds the
temperature measured by the collector sensor T1, the
collector pump deactivates. If the sum is lower than
the T1 value, the collector pump is active.
Additionally, to ensure stable operation of the heating
system, a control hysteresis of 3°C is applied.
