Settings menu 5
D 5.11 - Tpriority - Priority switching temperature menu 5.x = lower temperature limit for absolute priority
Charging the lower-priority tank is possible only after this temperature (Tpriority) is reached in the higher-
priority storage tank.
Setting range: 0-90 °C / default setting: 40 °C
D 5.12 - Charging interruption menu 5.x = interruption of charging into the lower priority storage tank
The charging of the lower-priority storage tank is interrupted after this settable time in order to check whether
the collector has reached a temperature level that allows charging in the higher-priority storage tank. If not,
charging the lower-priority storage tank continues until the next interruption.
Setting range: 5-90 min. / default setting: 10 min.
D 5.13 - Increase menu 5.x = temperature increase during charging interruption
The temperature increase is measured during interruption in charging to the lower-priority storage tank.
After 10 min. (Charging interruption) the solar pump(s) stop and the temperature increase is measured. If
Increase > 3 °C/min., Interruption time is extended until the switching condition S1-S2 < ΔT R1 for S2 storage
tank is met.
If the temperature increase does not reach the value set (Increase), the interruption is terminated and the
lower-priority tank continues being charged.
Setting range: 1-10 °C/min / default setting: 3 °C/min
- If the S2 temperature is below 40 °C, only the S2 (higher priority) storage tank is charged.
- If the S2 temperature is over 60 °C, only the S3 (lower priority) storage tank is charged.
- If the S2 temperature is between 40 and 60 °C and the condition S1-S2 < ΔT R1 is met (collector heat output
is sufficient), the S2 (higher priority) storage tank is charged.
- If the S2 temperature is between 40 and 60 °C and the condition S1-S2 < ΔT R1 is not met (collector heat
output is not sufficient), charging is diverted to S3 (lower priority) storage tank and the collector is checked at
regular intervals whether the temperature increase is sufficient. If yes, charging returns to the priority storage
tank (S2).
D 5.14 - Thermostat periods
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: od 00:00 to 23:59 / default setting: 06:00 to 22:00
D 5.15 - Party function
With the party function the storage temperature is heated
up once to the set temperature (Tset ) regardless of the
thermostat timer. The party mode is enabled by pressing
the „esc“ key for 3 seconds in the main menu. While this
mode is active, the system heats up to the set value Tset S3
(or Tmin S3 in energy saving mode), unattached to preset
thermostat times. The mode is ended once the required
temperature is reached.
D 5.16 - Energy saving mode
The energy saving mode sets the temperature limit when the additional storage tank heating (e.g. with
a heating rod) via R2 is switched on. In any case, this additional heating can be switched on during thermostat
operation only.
- If solar heat is available, additional heating is switched on when Teco S3 is reached and heats up to
Teco+hysteresis.
- When no solar heat is available, additional heating is switched on when Tset S3 is reached and heats up
to Tset S3+hysteresis, i.e. like in normal mode.
Additional heating mode. Setting range: ON, OFF / default setting: OFF
