Description
:
Install a flow switcher on the cold-water pipe,
and then open the tap, when there is flow
through the hot water pipe, flow switcher gets
signal and sends it to controller, and then DHW
pump is triggered to transport the hot water from
tank to tap. The running time of DHW pump is
adjustable, running time finished, DHW pump is
stopped.
Tap seems like a remote controller, it controls the running of DHW pump. This
control mode of DHW pump is an energy saving solution.
Open the tap for a short time, then flow switcher installed on the cold-water pipe
will get the flow signal and sends it to the controller, and then controller triggers
DHW pump P1 to transport the hot water from tank into circulation pipe. Then
when you open the tap again, hot water can flow out immediately, the running
time finishes, DHW pump will stop automatically. When no more hot water is
needed, to avoid hot water is cooled by circulation, DHW pump will be stopped
when its running time finished. And to avoid the DHW pump is triggered again
just after its stop, a parameter of interval time is designed for this purpose.
as default set, DHW pump runs for 3 minutes
(
adjustable range 1-30 minutes
)
and then ceases for 10 minutes (adjustable range 0-60 minute), same process
repeated within the running time section. Running time can be adjusted from
1-30Min; interval time can be adjusted from 0-60Min.
Note
:
1) To avoid the mixing of water in the tank with water in the circulation pipe, a
one-way valve should be installed before pump.
