Temperature threshold for absolute priority.
In systems with two storage tanks
charging of the lower-priority storage tank will never take place until this temperature at
sensor of the higher-priority storage tank is exceeded.
Interruption of charging into the lower priority storage tank.
The charging of
the lower-priority storage tank is interrupted after the settable time in order to check
whether the collector has reached a temperature level that allows charging in the high-
er-priority storage tank. If so, the priority storage tank is charged. If not, the increase is
measured, to check if charging of the priority storage tank will be possible shortly.
Extension of the charging pause due to temperature increase in the collector
For precise setting of the charging priorities for systems with multiple storage tanks,
the necessary temperature increase of the collector at which the interruption of the
charging into the lower-priority storage tank is extended by one minute is set here. The
interruption is extended because the temperature increase of the collector is expected
to enable charging in the higher-priority storage tank soon. As soon as ∆T conditions
are met, the priority storage tank is charged. If the rise in temperature falls below the
set value, then the charging of the lower-priority storage tank is enabled again.
Switch-off temperature at heat exchanger sensor
If this value is exceeded at the applicable sensor, the controller switches the associat-
ed pump and/or valve off. If the temperature falls below this value again and the other
conditions are also met, then the controller switches the pump and/or valve on again.
Danger
Temperature values that are set too high can lead to scalding or damage
to the system. Scalding protection must be provided by the customer!
