ST-460 - Watt

ST – 460 operation manual➔Solar pump - delivery [yes/no]In this installation, it is possible to deactivate the solar pump, forexample, to cool down the container with the auxiliary pump.IV.a.5) Scheme 5/10Installation 5/10 handles:➔ collector pump,➔ switching valve,➔ two accumulative tanks,➔ one direction of collectors location,➔ additional peripherals.Installation sensors:➔ collector sensor,➔ accumulation tanks sensors.Additional installation options:➔valve hysteresisThis setting relates to the valve control while cooling the collectorsensors in the holiday or alarm mode, as well as while unfreezing. Thevalve hysteresis determines the differential temperature between thetanks at which the valve switches to the opposite tank.➔tank 2 set temperatureIf the set temperature of the first tank is reached, the valve willswitch power to the circulation of the second tank. Using this function,the user sets the set temperature for the second tank.➔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, the auxiliary pump deactivates.The pump will activate again after the tank temperature drops below theset value by the tank 2 hysteresis value.➔Maximum heating time Z2After switching the circulation to the other tank, this parameterdetermines how long it will be additionally heated (if conditions ofswitching to the first circulation haven't been met yet)➔Oscillation pauseAfter maximum heating time Z2, an oscillation pause takes place(the pump is deactivated), ensuring temperature stabilization. If duringsuch pause the temperature of the first tank sufficiently drops, thevalve will switch. Otherwise, the maximum heating time cycle Z2 andthe oscillation pause are repeated.- 14 -
