Setting the maximum buffer cylinder target flow temperature for the
domestic hot water station. The set maximum target flow temperat-
ure must be lower than the maximum flow temperature for the heat
generator.
If the maximum target flow temperature is set too low, the
domestic hot water station cannot reach the target temperature.
While the target temperature is not reached, the system control
does not enable the heat generator for heating mode.
You can find the maximum flow temperature in the installation in-
structions for the heat generator.
Factory setting:
–
80 °C
–
65 °C if basic system diagram 8 is selected
Setting the maximum cylinder temperature. The solar circuit stops
the cylinder charging as soon as the maximum cylinder temperat-
ure has been reached.
Factory setting: 75 °C
Display of the current temperature at the solar collector
Display of the current control command at the solar pump
Display of the current temperature at the solar yield sensor
Entering the volume flow to calculate the solar yield. If a solar
pump station is installed, the system control ignores that value that
has been entered and uses the volume flow that is supplied from
the solar pump station.
The value 0 means the automatic recording of the volume flow.
Factory setting: Auto
Accelerated recording of the collector temperature. When the func-
tion is activated, the solar pump is switched on for a short time and
the heated solar fluid is transported to the measuring point more
quickly.
Factory setting: Off
Setting the maximum temperature that must not be exceeded
in the solar circuit. If the maximum temperature at the collector
sensor is exceeded, the solar pump switches off to protect the
solar circuit against overheating.
Factory setting: 130 °C
Setting the minimum collector temperature that is required for the
solar charging switch-on differential. The differential temperature
control can only start once the minimum collector temperature has
been reached.
Factory setting: 20 °C
Setting the time period during which the solar circuit is purged. The
system control stops the function once the specified purging time
has elapsed, the solar circuit protection function is active or the
max. cylinder temperature has been exceeded.
Factory setting: 0 min
Current volume flow of the solar pump station
Setting the differential value for starting the solar charging.
If the temperature difference between the cylinder temperature
sensor at the bottom and the collector temperature sensor is
greater than the set differential value and the set minimum
collector temperature, the cylinder charging is started.
The differential value can be defined separately for two connected
solar cylinders.
Factory setting: 12 K
Setting the differential value for stopping the solar charging.
If the temperature difference between the bottom cylinder temper-
ature sensor and the collector temperature sensor is smaller than
the set differential value and the set minimum collector temper-
ature, the cylinder charging is stopped. The switch-off differential
temperature value must be at least 1 K less than the set switch-on
differential temperature value.
Factory setting: 5 K
