Solar Water Heater Controller Split Water Wifi Remote Control 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 (Delta 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 (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 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. Accuracy of temperature measuring: ±2centigrade. Range of collector temperature measuring: -10220centigrade. Range of tank temperature measuring: 0110centigrade. Suitable power of pump: 3.
Inputs: 1 x Pt1000 sensor. 2 x NTC10K, B3950 sensor. Outputs: 1 relays, for circulation pumps.1 relay for electrical heater. Main menu DT O & DT F Temperature difference function. EM Emergency collector temperature (emergency switch-off temperature of collector). CMX Maximum limited collector temperature (collector cooling function).
CMN low temperature protection of collector. CFR frost protection of collector.
SMX Maximum temperature of tank. Celsius and Fahrenheit temperature transferring. LOAD Recovery to factory setting.
1 PT1000 temperature sensor (f650mm, cable length 1.5meter). 2 NTC10K temperature sensor (f650mm, cable length 3meter). WIFI Remote Control is available for SR208C WIFI only. There may be some delays due to flight, holiday, weather, local post, local natural disaster impact. It must also be in the original packaging.
