4.1 Tmin sensor S8
If the temperature registering at sensor S8 exceeds this value and other conditions are met, the controller will activate the
associated pump and/or valve. If the temperature registering at the sensor drops by 5 °C below the setting, the controller
will shut off the pump and/or valve again.
Settings range: 0 °C to 99 °C / Default: see table.
4.3 Storage priority 1
This determines the order in which the storage targets are filled. If the same priority is set for both targets, flow will not be
switched until the moment when the active target can no longer be buffered.
Settings range: 1 - 2 / Default: see table.
4.4 Δ T On, storage 1 = Temperature difference for buffering storage 1:
If the temperature between the reference sensors is exceeded and other conditions are also met, the controller will acti-
vate the connected relay. If the temperature drops below ΔT Off, the relay deactivates.
Settings range: ΔT On, 8 °C to 50 °C / ΔT Off, 2 °C to 14 °C / Default: see table.
b
If the selected temperature difference is too small, the operational effectiveness of the controller might be affected,
depending on the system layout and the positioning of the sensors. Special switching functions can be introduced
for speed control (see “6.3. - Speed control R1 / R2”).
4.5 Tmax storage 1 = Maximum temperature for buffering storage 1
If the temperature registering at sensor S1 exceeds this value, the controller will shut off the associated pump and/or
valve. If the temperature returns below this value and other conditions are met, the controller will activate the associated
pump and/or valve again.
Settings range: 0 °C to 99 °C / Default: see table.
b
If temperature settings are too high, this could cause scalding or damage to the system. Scalding protection must
be provided by the user!
4.6 Storage priority 2
This determines the order in which the storage targets are filled. If the same priority is set for both targets, flow will not be
switched until the moment when the active target can no longer be buffered.
Settings range: 1 - 2 / Default: see table.
4.7 Δ T On, storage 2 = Temperature difference for buffering storage 2:
If the temperature between the reference sensors is exceeded and other conditions are also met, the controller will acti-
vate the connected relay. If the temperature drops below ΔT Off, the relay deactivates.
Settings range: ΔT On, 8 °C to 50 °C / ΔT Off, 2 °C to 14 °C / Default: see table.
b
If the selected temperature difference is too small, the operational effectiveness of the controller might be affected,
depending on the system layout and the positioning of the sensors.
4.8 Tmax storage 2 = Maximum temperature for buffering storage 2
If the temperature registering at sensor S2 exceeds this value, the controller will shut off the associated pump and/or
valve. If the temperature returns below this value and other conditions are met, the controller will activate the associated
pump and/or valve again.
Settings range: 0 °C to 99 °C / Default: see table.
4.17 T-priority = Temperature threshold giving absolute priority
In systems with multiple buffer cylinders, the storage having the lower priority will be buffered only when the temperature
threshold set at the sensor associated with the higher priority storage has been exceeded.
Settings range: 0 °C to 90 °C / Default: see table.
4.18 Buffer time = Interruption of flow to lower priority storage
The flow of water to the storage target with lower priority is shut off after a certain duration (settable), in order to establish
whether or not the temperature level in the collector has increased sufficiently to begin buffering the higher priority target.
If the conditions are right, the priority storage will be buffered. If not, the increase is measured (see “4.19. - Increase”) in
order to establish how soon it will be possible to begin buffering the priority storage target.
Settings range: 1 to 90 minutes / Default: see table.
4.19 Increase = Extension of buffering pause due to temperature increase in the collector
To allow an accurate setting of the buffering priority in systems with multiple storage targets, this menu is used to set the
increase in temperature of the collector needed to ensure that the interruption of the flow supplied to the lower priority
storage is prolonged by one minute. The interruption is prolonged because it is expected that the temperature rise at the
collector will allow the lower priority storage to be buffered sooner. Once the requisite ΔT conditions are established, heat
will be directed to the priority storage. If the increase in temperature is less than the set value, then buffering of the lower
priority storage will be enabled again.
Settings range: 1 °C to 10 °C / Default: see table.
