100-240V SR868C8 Solar Water Heater Controller Temperature Controller Solar Controller Thermal Controller Solar NTC10K PT1000

SR868C8 has been replaced by SR81 with some optimization and same apparance, if you need manual first, please send us message with email address.

​SR81 3000W and 4000W version has no power cable with plug.

the default setting dont show T3, because many people dont use T3, so we hide T3 in the new version.

ONLY when you open the auxiliary heating function and set the sensor T3. Then the T3 will display.

Working Principle

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 (Delta 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 (Delta 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 (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.
