CONTROLLER of SOLAR WATER HEATER, 220V, 3 temperature sensors, for hot water Link:ebay.au/itm/CONTROLLER-SOLAR-WATER-HEATER-220V-3-temperature-sensors-hot-water-/330941492587?pt=AU_HotWaterSystems&hash=item4d0da66d6b Application: It is used for seperated pressurized solar water heating system. Voltage: 220v Introduction: 1 collector array – 1 storage tank – 1 pump and auxiliary heating Description: The solar circuit pump (R1) is switched on as soon as the switch-on temperature difference (△Ton) between the collector array (T1) and the storage tank (T2) is reached. If the temperature difference between the collector array (T1) and storage tank (T2) drops below the switch-off temperature difference (△Toff), or the temperature of storage tank (T3) reaches the preset maximum storage temperature, then the solar circuit pump ( R1) is switched off. Back-up heating by auxiliary boiler (detailed see paragraph 4.3): Within the preset time section of back-up heating, if the temperature T3 is below the switch-on temperature, then the circulation pump ( H1) of back-up heating is triggered, when T3 is heated to the switch-off temperature, circulation pump H1 of back-up heating is ceased.
