Digital Electric Water Heater Thermostat for Swimming Pool, SPA & Hot Tub — Adjustable Precision Controller 9KW 220V_D

Precision digital thermostat designed for electric water heating applications including swimming pools, spas and hot tubs (9KW, 220V_D). Ensure the supply voltage matches the rating on the unit; the difference between supply and rated voltage must not exceed ± 10%. During installation keep the temperature sensor away from power conductors and prevent direct contact or close proximity. Maintain a clear separation between sensor wiring, power lines and the output relay terminals. The controller uses broad refrigeration technology for straightforward operation and accurate temperature regulation, plus enhanced anti-interference performance. Sensors are finished with precision machining and a moisture-resistant package to deliver stable, reliable operation in automatic refrigeration and heating control systems.
