Setting of which priority the swimming pool will be solar heated. The priority for
the DHW and charging buffer is set under Prog. no. 3822.
- Priority 1: the swimming pool is heated, before the buffer is charged.
- Priority 2: the swimming pool is heated, while the buffer is charged.
- Priority 3: the swimming pool is heated, after the buffer is charged.
This parameter sets whether the swimming pool heating by solar charging has
priority or not. If the swimming pool temp reaches the heating limit set here, the
collector pump is switched off. It is again released if the swimming pool temp has
dropped by 1 °C below the maximum heating limit temperature.
Setting of whether the swimming pool heating can be done by solar energy or
not.

8.4.10 Primary contr/system pump

With these boundaries a range for the flow setpoint can be defined.
This parameter can set whether during active heat generation lock the system
pump will also be locked or not.
- Off: The system pump will not be locked.
- On: During active heat generation lock the system pump will also be locked.
For the admixture the boiler flow temperature actual value must be higher as the
requested setpoint of the mixer flow temperature, since these cannot otherwise
be corrected. The controller from the boiler temperature setpoint from the boost
set here and the current flow temperature setpoint.
Setting the actuator running time of the used mixing valve.
- Before buffer storage tank: the primary controller/feed pump is arranged with
existing buffer storage tank hydraulically before the buffer storage tank
- After buffer storage tank: the primary controller/feed pump is arranged with
existing buffer storage tank hydraulically after the buffer storage tank

8.4.11 Boiler

The boiler is only put into operation if the mixed outside temperature is below
the threshold set here. The switching difference is 0.5°C.
Under Prog. no. 4810 (full charge charging buffer) is selected, whether and when
the charging buffer is fully charged despite automatic heat generation lock. Un-
der Prog.no. 2203 it is set, whether the boiler takes part in the full charge or not.
- Off: the boiler does not take part in the full charging of the charging buffer.
- On: the boiler takes part in the full charging of the charging buffer.
As a protection function the boiler temperature setpoint can be limited below by
the minimum setpoint (prog.no. 2210) and above by the maximum setpoint
(prog.no. 2212).
