How to perform a manual power override

If the Control loses power and you need to operate the valve, you can do this via a manual override. 

1. Lift the rubberized flap on the Control next to the power input port to reveal the manual override port. 
2. Insert a 9 volt battery into the port and hold it firmly against the back of the port. The orientation of the battery is important - the negative terminal must be on the left with respect to the top of the Control (the side of the unit with the "OPEN" and "CLOSE" buttons). 
3. When the battery is inserted properly and held firmly in the manual override port, the Control will power on and the lights on the top of the unit will light up.
4. You can now open or close the Control valve using the buttons on top of the Control
