ST-460 - Watt

TechNote. Setting the (SERVICE MENU > Solar collector) option of the solarcollector applies equally to the collectors situated in both directions.Additional installation options:➔ pump activation delta 2 (same as for the main pump),➔ pump deactivation delta 2 (same as for the main pump)IV.a.4) Scheme 4/10Installation 4/10 handles:➔ collector pump,➔ auxiliary pump (Pump 2),➔ accumulation tank,➔ one direction of collectors location,➔ additional peripherals.Installation sensors:➔ collector sensor,➔ two accumulation tank sensors➔ pellet boiler temperature sensor.Additional installation options:➔additional heating activation deltaIn this installation model, there is additional circulation for heatingthe tank with the use of CH (Central Heating) boiler. If the presenttemperature of the tank is lower than the preset tank temperature by atleast the set value of the activation delta (it is the difference betweenthe set temperature and the current tank temperature), the auxiliarypump (from the boiler) will activate in order to additionally heat theaccumulation tank up (provided that the boiler temperature is higherthan the tank temperature) This setting will be enabled only in hours setby the user (from, until)➔from➔until➔Energy delivery [yes/no]This scheme makes it also possible to deliver energy (e.g.. to the CHinstallation) above the set threshold temperature of the tank.➔Delivery thresholdThis scheme makes it also possible to deliver energy (e.g.. to the CHinstallation) above the set threshold temperature of the tank.➔Delivery hysteresisIt is the difference between the set delivery threshold temperaturewhen the auxiliary pump is activated) and the deactivationtemperature of this pump.- 13 -
