Funct.
Activation / Deactivation
Activated, Deactivated Deactivated
The Tube collector function helps overcome the non-ideal sensor position with
some tube collectors.
This function operates within an adjusted time frame. It activates the collector
circuit pump for an adjustable runtime between adjustable pauses in order to com-
pensate for the delayed temperature measurement.
If the runtime is set to more than 10 seconds, the pump will be run at 100 % for
the fi rst 10 s of the runtime. For the remaining runtime, the pump will be run at the
adjusted minimum speed.
If the collector sensor is defective or the collector is blocked, this function is sup-
pressed or switched off.
2-collector systems
In 2-collector systems, the tube collector function is available for each individual
collector fi eld.
If one of the collector fi elds is being loaded, the heat transfer fl uid fl ows through
the inactive fi eld and only the corresponding relay is energised.
Multi-store systems
If the tube collector function is activated, the speed of the solar pump will decrease
to the minimum speed during the loading break time. The solar loading of the sub-
ordinate store will continue.
In 2-collector systems, during the loading break time, the collector fi eld which has
been active before the loading break time remains active during the loading break
time, unless the tube collector function of the inactive fi eld becomes active.
