Waiting time parallel op (3827)
Parallel operation is feasible when using solar primary pumps subject to
there being sufficient solar energy available. For this, in addition to the
storage tank currently being heated, the next storage tank in the priority
order can also be heated in parallel. The storage tank switching on for
parallel operation can be delayed and stepped by the value set here.
The setting "- - -" switches off parallel operation.
Delay secondary pump (3828)
The start-up of the secondary pump can be delayed to ensure that it only
switches on if the primary circuit is already at the correct temperature.
Collector start function (3830)
If the temperature at the collector with the pump turned off is not
measured correctly (e.g. with vacuum tubes), then a periodic switching on
of the pump is possible.
Caution
The temperatures at certain collectors cannot be measured
correctly if the pump is switched off. For this reason, the pump
must be activated from time to time.
Min run time collector pump (3831)
The collector pump is periodically switched on for the running time set
here.
Collector start function on (3832) and Collector start function
off (3833)
The time when the collector start function starts or stops is set here.
Collector start funct grad (3834)
As soon as there is a temperature increase on the collector sensor, the
collector pump switches on. The higher the value selected here, the
greater the temperature rise must be.
Collector frost protection (3840)
In order to prevent freezing of the collector, the collector pump will be
activated at the temperature set here.
Collector overtemp prot (3850)
In the event of a risk of overheating, charging of the storage tank will be
continued in order to reduce the heat. Charging of the storage tank stops
once the storage tank safety temperature has been reached.
Evaporation heat carrier (3860)
Pump protecting function, to prevent overheating of the collector pump in
case of evaporating danger of the heat carrying medium due to high
collector temperature.
Pump speed min (3870) and Pump speed max (3871)
The charging setpoint of the storage tank with the highest charging priority
and the collector temperature are used for speed regulation. The speed is
calculated so that the collector temperature is 2 °C below the start
temperature. If the collector temperature increases due to stronger
sunlight, the speed is increased. If the collector temperature falls below
this setpoint, the speed is reduced. The pump speed can be restricted via
the minimum and maximum parameters.
Antifreeze (3880)
Information of the antifreeze used.
Antifreeze concentration (3881)
Input of antifreeze concentration for usage measurement of solar energy.
