Settings
5.10 Priority sensor
Charging priority in systems with two storage tanks
A setting must be made as to which storage tank (storage tank sensor) has priority for
charging. Charging of the lower-priority storage tank is interrupted at regular intervals
to check whether the temperature increase at the collector can enable charging of the
higher-priority storage tank.
Setting range: S2 or S3/default setting: S2
5.11 T priority
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 ex-
ceeded.
Setting range: from 0°C to 90°C/default setting: 40°C
5.13 Increase
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.
Setting range: from 1°C to 10°C/default setting: 3°C
5.12 Loading time
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 higher-priority storage tank. If so, the priority storage tank is charged.
If not, the increase is measured (see 5.13), to check if charging of the priority storage
tank will be possible shortly.
Setting range: from 1 to 90 minutes/default setting: 10 minutes
5.14 Thermostat periods
Thermostat activity times
Set the desired periods of time when the thermostat should be active. 2
periods can be set per day, settings can also be copied to other days.
Outside the set times the thermostat is switched off.
Setting range: from 00:00 to 23:59 /default setting: 06:00 to 22:00
