Pump run
time
Pump run time in lower priority. If the
increase in temperature during flushing
does not suffice to switch into higher pri
-
ority, lower priority will be permitted for
this time.
If the pump run time is set to 0,
lower priority will only permitted once
the higher priority consumer reaches its
maximum threshold (= absolute priority)
(FS = 20 min)
Delay
Delay time in lower priority. It equals the
time, in which the collector should be
able to reach the necessary temperature
for operation in higher priority. If this time
is set to 0, the solar priority timer is deac
-
tivated. (FS = 5 min)l
Flushing time
Specification of the flushing time after the idle time.
Within this time, half the collector‘s fluid content should
be able to be pumped past the collector sensor.
(FS = 15s)
Flushing outputs
Outputs used for flushing. If a control output is assigned
to the output, the analogue level for full speed will be
output. (FS = 1)
Options: Combination of all outputs
Radiation sensor
Specification of an input, if a radiation sensor is used. If
the radiation sensor exceeds a set radiation threshold
(insolation value), the priority timer will be started. With
-
out a radiation sensor, the timer will be started accord
-
ing to the monitored collector temperature. (FS = -----)

S1 to S6
