Final Connections

R
Connect the valve controller's valve control
cable (2-pin) to the control cable of the
motorized valve. Ensure the arrow of the cable
connector aligns with the arrow of the other
cable connector. Twist the collar of the
connector tight.

Manual Operation

S
It is recommended to always use the app or the
valve controller's SET button to operate your
motorized valve.
Lift the knob on the top of the motorized valve
and turn it by hand, until it can not be turned.
Check the valve position indicator.
If you are not using the valve status feature or if
your valve controller does not have the valve
status feature, to avoid the app from indicating
the wrong valve status, if you manually closed
the valve, for example, manually open it again.
Do not open it via the app, after manually closing
it and vice versa, otherwise the app will incor-
rectly indicate the valve is closed.
