Collector minimum temperature
The minimum collector temperature is the minimum switch-on temperature which
must be exceeded for the solar pump (R1 / R2) to switch on. If the collector tem-
perature falls below the adjusted minimum temperature, ❄ is displayed (ashing).
Note:
In systems with east- / west collectors 2 separate menus (COL and
COL 2) will be displayed.
Tube collector function
This function is used for improving the switch-on behaviour in systems with
non-ideal sensor positions (e. g. with some tube collectors).
This function operates within an adjusted time frame. It activates the collector
circuit pump for an adjustable runtime between adjustable standstill intervals in
order to compensate for the delayed temperature measurement.
If the runtime is set to more than 10 seconds, the pump will be run at 100 % for
the 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 eld.
In 2-collector systems, the tube collector function will affect the inactive collector
eld only. The solar pump of the active collector eld will remain switched on until
the switch-off conditions are fullled.
Note:
If the drainback option is activated, the tube collector function will not
be available.
