Adjustment channelsOscillating break time / oscillating chargetime/ collector rising temperature:The controller checks the stores regarding loadingfacilities (switch-on difference). If the prioritystore cannot be loaded, the lower-ranking store ischecked. If the lower-ranking store canbe charged,this is effected by the so-called "oscillating chargetime" (tRUN). After the expiration of the oscillatingcharge time, loading is stopped. The controllercontrols the increase of the collector temperature. Ifthis temperature increases by the rise temperatureof the collector (∆T-Col 2 K, fixed software value),the expired break time is again reset to zero andthe oscillating break time (tSP) starts over again. Ifthere after the switch-on conditions of the prioritystoreare not reached, the loading of the lower-rankingstore will be continued. If the priority switch hasreached its maximum temperature, the oscillatingcharge is not carried out.4.1.16 Recooling functionIf, as a result of of the system cooling OCX, thestore temperature is higher than the store maximumtemperature (S MX/S1MX/S2MX) and the collectortemperature is at least lower than 5K, the solarsystem continues running until the store is cooleddown to the adjusted store maximum temperature(S MX/S1MX/S2MX) via collector and pipes. Inmulti storage systems the recooling is generallyeffected at store 1.OREC:Option recoolingAdjustment range:OFF ...

After the expiration of the solar pumpruntime the current collector temperature is storedas a new reference value. If the measured temperature(new reference value) is again exceeded by 2 K,the solar pump switches-on for 30 seconds.O TC:Tube collector specialfunctionAdjustment range:OFF ...
