ST-460 - Watt

ST – 460 operation manualacceptable temperature (SERVICE MENU > Accumulation tank > Tank 1max temp.)IV.c.2) Heating minimum temperatureIt is the collector's threshold temperature below which the pumpdoes not activate. The exception are emergency modes, manualoperation or collector defrosting.IV.c.3) Alarm hysteresisUsing this function, the user declares the collector's alarmhysteresis value. If the tank reaches the alarm temperature (theoverheating temperature) and the pump activates, its deactivation willoccur when the collector's temperature decreases below the maximumtemperature by this hysteresis value.IV.c.4) Defrosting timeUsing this function, the user determines, for how long the pump will beactivated after the Collector defrosting function activation.IV.c.5) Anti-freeze temperatureOwing to different freezing temperature of the fluid in the solarinstallation, Antifrost temperature has been introduced. This parameterdetermines minimum safe temperature at which liquid glycol does notfreeze (temperature measured on the collector). In the case ofsignificant collector temperature drop (down to the value of thisparameter), the pump will be activated and will work continuously untilheating the collector up to a safe temperature. The settings range ofthis coefficient is within -50: +10°C.- 22 -
