Intelligent Controller SR208C, Separated Pressurized Solar Water Heater Solar Workstation

 

Intelligent controller SR208C for Separated pressurized solar water heating system

 

Description:


Suitable for separated pressurized solar water heating system
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 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.
