Products function and features
- Equipped with water volume server, block valve control function, according to different usage request.it can adjust the water inlet volume automatically, air inlet volume double adjustment.
- Equipped with inlet water temperature sensor, utilize FF, FB double control ways to realize swift and accurate constant temperature.
- Gas proportional control valve output constant electricity current DC20-260mA, it can be applicable for different brands gas valve.
- Keep memory of user' s habit, the system can react quickly and increase the water temperature rapidly when using again.
- Equipped with ОТ (OpenTherm) line controller function (Let the terminal dangling when no usage.)
- Equipped with anti-freezing function(DHW request have priority), to prevent system pipeline from freezing and damaging the machine, Under Down status, when it detects the pipe water temperature to decrease to below 6°C, it will start the anti-freezing heating device. When the temperature reaches 15°C, shut down heating output and enter down status.
