110v controller for seperated pressurized solar water heating system Display dimensiony:120mm * 120mm *18mm 3 sensors (1*Pt1000 + 2*NTC10K) Suitable for 1 collector array * 1 storage tank * 1 pump and auxiliary heating Function Introduction:
The solar circuit pump (R1) is switched on as soon as the switch-on temperature difference (△T on) 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 (△T off), , 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: 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. technical data
