CONTROLLERs & PUMPs

This listingincludes: 1 unit of controller for solar water heater, 220V.

Application:

It is for the solar hot water heating system: 1 collector array – 1storage tank – 1 pump and auxiliary heating.

Brief Introduction: 

The solar circuit pump (R1) is switched on as soon asthe switch-on temperature difference 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, or the temperature ofstorage tank (T3) reaches the preset maximum storage temperature, then thesolar circuit pump (R1) is switched off. Back-up heating by auxiliary boilerWithin the preset time section of back-up heating, if the temperature T3 isbelow the switch-on temperature, then the circulation pump ( H1) of back-upheating is triggered, when T3 is heated to the switch-off temperature,circulation pump H1 of back-up heating is ceased.
