Description: This listing includes: 1 unit of controller for solar water heater, 220 V (Wi-Fi version). It is suitable for separated solar hot water system. Application capacity: Max.number of collectors:1 Max.number of storage tanks:1. Max.number of relays:2. Max.number of sensors:3. Max.number of visualization application system:1 Brief Introduction: The controller calculates the temperature difference between collector sensor T1 and tank sensor T2. If the difference is larger than or identical to the adjusted switch-on temperature difference, the solar circulation pump (R1) will be switched on and the tank will be loaded until the switch-off temperature Difference or the maximum tank temperature is reached.
