3KW Electric Pool & SPA Precision Thermostat — Water Heater Controller for Swimming Pools and Bathtubs

Designed for in-pool installation, this 3KW electric thermostat is built specifically for swimming pools, spas and bathtubs. When adding hot water and running the pump, the thermostat automatically engages its heating/insulation function to hold the water temperature at 42°C, creating a more comfortable bathing or swimming environment. Safety is provided by an ultra-high temperature protection switch with a reset button: if the temperature rises over60 °C the protection switch will automatically trip and cut power (power off).
