4.1.14 Tube collector special function
If the controller measures an increase of 4 °Ra compared
to the collector temperature tankd at last, the solar
pump is switched-on to 100 % for about 30 seconds.
After expiration of the solar pump runtime the current
collector temperature is tankd as new reference value. If
the measured temperature (new reference value) is again
exceeded by 4 °Ra, the solar pump again switches-on for 30
seconds. If the switch-on difference between collector and
tank is again exceeded during runtime of the solar pump
or the standstil of the system, the controller automatically
switches over to solar charging.
If the collector temperature drops by 4 °Ra during standstill,
the switch-on value for the special tube collector function
will be recalculated.
