110V controller of solar water heater, used for separated pressurized solar hot water system

Description:

​​Manual in English

This listing includes: 1 unit of controller for pressurized solar water heating system, 110V.

Application:

It can be used for the solar hot water heating system: 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.
