DW-Z flow switch for hot water control
The DW-Z flow switch helps save energy without sacrificing comfort!
Hot water circulation systems are sometimes equipped with a pump and time switch, which circulates hot water during a set time without anybody using water. The DW-Z flow switch provides warm water only when you need it. When the hot water tap is opened, the circulation pump starts. The circulation pump is activated and immediately distributes heat. If the tap is closed, the pump will remain in operation for a short while. This relay time is adjustable between 1 and 18 minutes using the interval button. "Pump on" mode is indicated by a green LED.
