ST-460 - Watt

ST – 460 operation manualtemperature on the collector increases above the temperature of thetank by the value of the solar pump activation delta.When the pump deactivates after reaching the set temperature,its reactivation will take place if the temperature falls below the setvalue by the value of the tank hysteresis (the hysteresis value is setin: SERVICE MENU > Accumulation tank > Tank hysteresis)2. Collector defrosting.Using this function, you can manually activate the collector pumpin order to melt snow on the solar panels. After activation, this mode isactive for the time specified by the user, and then the controller returnsback to the automatic operation (the defrosting time is set in: SERVICEMENU > Solar collector > Defrost time). The function can be switched offmanually after a shorter operation time by selecting a different operationmode.3. Holiday mode.After holiday mode activation, the pump works when thetemperature of the collector increases up to the overheating temperaturevalues (SERVICE MENU > Solar collector > Overheating temperature)reduced by the value of the Holiday delta parameter (SERVICE MENU >Accumulation tank > Holiday delta), or when the collector temperature islower than the temperature of the tank. When this condition is met, thepump activates to cool down the collector (or the container) Deactivationof the pump takes place after reducing the temperature by 5°C. Such apump operation algorithm in the holiday mode allows for maximumenergy saving.4. Manual operation.In this function, in order to control the installation devices, theuser can manually (by pressing the selected device icon) activate anddeactivate:-solar pump,-second solar pump or switching valve,-additional device (voltage-free contact e.g.. for firing up the pelletboiler)III.c) TimerIn this function, the user sets current time, according to which theregulator will be operating.- 8 -
