ST-460 - Watt

ST – 460 operation manualafter the collector pump deactivates.IV.b.2) Maximum tank temperature 1This option is for declaring the maximum acceptable safetemperature value, up to which the tank will be allowed to heat itself.If the collector reaches the alarm (overheating) temperature, the pumpwill be activated automatically in order to cool down the heatedcollector, regardless of the temperature set. The pump will work untilreaching the container's maximum temperature or until drop in thecollector's temperature by the alarm hysteresis value (see: SERVICEMENU > Solar collector > Alarm hysteresis)IV.b.3) Tank hysteresisUsing this function, the user declares the tank hysteresis value. Ifthe tank reaches the set temperature and the pump is deactivated, itreactivates after the tank temperature drops below the set value by thevalue of this hysteresis.IV.b.4) Manimum tank temperature 1This parameter is for declaring the minimum acceptabletemperature value, down to which the tank will be allowed to cool itself.Below this temperature, the pump will not activate in any operatingmode (apart from manual operation)IV.b.5) Cooling to the set temperatureSometimes there is a situation when the collector reaches theoverheating temperature and emergency start - up of the pump occursin order to cool it down. In this case, the tank receives heat untilexceeding the set temperature (up to the maximum temperature) Toprevent accumulation of too hot water in the container, thewychładzanie do zadanej function should be started. After activating thisoption, when the collector temperature drops below that of thecontainer, the pump will activate in order to cool down the tank until itreaches the preset temperature.IV.b.6) Holiday deltaThis function is active in the holiday operating mode only. Thisparameter determines, how many °C before reaching the collectoroverheating temperature the pump will be activated in order to cool itdown. Deactivation of the pump occurs after reducing the collectortemperature by at least 5°C.- 20 -
