TechIV.a.10) Scheme 10/10Installation 10/10 handles:➔ collector pump,➔ switching valve,➔ accumulation tank,➔ boiler return circulation,➔ one collectors’ location direction➔ additional peripherals.Installation sensors:➔ collector sensor,➔ two accumulation tank sensors.➔ boiler return sensor.This installation is equipped with a valve which, in the case ofexcess of hot water in the tank, will switch the boiler return circulationin order to additionally heat it up (delivering excessive heat), which willresult in solid fuel saving.Additional installation options:➔ Delivery ThresholdThe parameter is used to set the threshold tank temperature atwhich the valve will switch to additional boiler return heating.➔ Output HysteresisWhen the output threshold temperature is reached, the valve willswitch the power supply to the boiler return circulation. Re-switchingthe valve will take place after cooling down the tank by the outputhysteresis value.➔ Activation DeltaThis parameter determines the maximum difference between thetank temperature and the boiler return circulation temperature atwhich the valve switches to additional boiler return heating.➔ Deactivation DeltaThis parameter determines the minimum difference between the tanktemperature and the boiler return circulation temperature at which thevalve switches to the traditional boiler circulation (without additionalheating)IV.b) Accumulation tankIn this menu, the user sets all the parameters concerning the tank(heat container)IV.b.1) Set temperatureThis function is used to set the preset temperature in the container- 19 -
