Features DUAL-CHANNEL OUTPUT CONTROL: The solar temperature controller features dual-channel output control. One channel manages the temperature difference between two temperature zones. The other channel controls electric heating, ensuring constant temperature within the controlled temperature difference range. FAST RESPONSE: Equipped with advanced sensors and control algorithms, the controller precisely perceives ambient temperature changes and responds rapidly. AUTOMATIC FUNCTION: The solar temperature controller automatically starts the pump circulation when the temperature difference reaches the set value to balance the temperature. RELIABILITY AND STABILITY: The solar temperature controller adopts stable hardware and quality software design, ensuring robust performance. It provides a stable temperature control solution for users, capable of running smoothly over extended periods. PROGRAMMABLE FLEXIBILITY: The solar temperature controller offer powerful programming capabilities. Users can set different parameters and needs as required, making the controller adaptable to various complex control demands and suitable for different industries and applications. Features: The products are used in solar water heater, the temperature difference and temperature to control the output. It is provided with two output control, temperature difference control two temperature zone. When the temperature reaches the set value, it automatically runs the water pump circulation and makes the two temperature zone temperature equilibrium. The other channel controls electric heating, when the solar heating failed to reach the set temperature, the electric heating system can automatically start and heat to the set temperature. It will control heating system and automatically makes water temperature stay in temperature deference range.
