ST-460 - Watt

ST – 460 operation manualdrops, the first tank pump will be activated, (the second pump isturned off). Otherwise, the Z2 maximum heating time cycleand the oscillation pause are repeated.➔ pump 2 activation deltaThis function determines the difference between the collector andthe second tank, at which pump 2 starts to work (it is the thresholdpump activation value) If the operation algorithm is set on tank priority1, pump 2 will activate only after further heating up the first tank(when the pump 2 activation delta condition is met)➔ pump 2 deactivation deltaThis function determines the difference between the collectortemperature and the second tank temperature, at which pump 2deactivates.IV.a.7) Scheme 7/10Installation 7/10 handles:➔ collector pump,➔ second tank pump,➔ two accumulative tanks,➔ one direction of collectors location,➔ additional peripherals.Installation sensors:➔ collector sensor,➔ two main accumulation tank sensors➔ additional accumulation tank sensorAdditional installation options:➔ tank 2 set temperatureThis function is used to set the set temperature of the secondtank, after the tank 2 pump(collector pump 2) deactivates.➔ maximum temperature of the 2 tankThis option is for declaring the maximum acceptable safetemperature value, up to which the second tank will be allowed to heatitself in the case of overheating the collector.➔ tank 2 hysteresisAfter reaching the set temperature, pump 2 deactivates. Thepump will activate again after the tank temperature drops below thepreset one by the tank 2 hysteresis value.➔ operation algorithmWith this option, the user selects the operation mode of thepumps. The pumps can operate in the following modes:a) tank priority 1 - first, tank 1 is being heated (only pump 1operates ), and, after reaching the set temperature, pump 2 is activated- 16 -
