If so, redo the connecons. You may oponally wrap the splices with electrical tape Refer to Install or Replace the Baeries (Gas/Water Valve Controller) secon on page 41 for the installaon of baeries for the controller 1. Reversing the wiring connecon may be required if the manipulator/motorized valve does not operate. Do this by moving each controller wire to the opposite wire on the manipulator/motorized valve 2. Aer the connecon, proceed to page 23-25, for tesng 21 Diagram (A): Connect the manipulator to the controller Diagram (B): Connect the motorized valve to the controller 22 D-4. Test the Controller and Manipulator/Motorized Valve D-4-1. Test the Controller and Manipulator (see Illustraon Next Page) Test the controller several mes by pressing the SET buon and watching for the smooth closing /opening of the valve. Then, use the YoLink app to open and close the valve If Not Working Properly:
- Verify the handle can be rotated 90 degrees, otherwise the valve cannot be fully opened or closed
- With the valve in the closed posion, the screws holding the valve operang pins will be much more accessible, so this is a good me to readjust them so that they are grasping the valve handle securely. If needed, use a Phillips screwdriver to ghten the pins securely in place
- If you are unable to get the controller and/or manipulator to operate correctly, double-check the installaon as needed. Do not proceed to the next step unl the manipulator opens and closes the ball valve properly
- If it is sll not working properly, Please refer to addional troubleshoong informaon on page 46, and Customer Service hours and contact informaon on page 51. For mechanical issues with the manipulator, sending us photos and/or a brief video of the issue may be benecial in assisng you 23 Water Pipe SET Buon The valve is opened The valve is closed 24 D-4-2. Test the Controller and Motorized Valve Turn on a water tap rst, then test the controller several mes by pressing the SET buon to open or close the valve and conrming that water ow at the tap stops completely (while the valve should be closed) and ows with no loss of pressure (while the valve should be open). Then, use the YoLink app to open and close the valve If Not Working Properly:
- If you are unable to get the controller and/or motorized valve to operate correctly, double-check the installaon as needed. Do not proceed to the next step unl the motorized valve opens and closes the ball valve properly
- If it is sll not working properly, Please refer to addional troubleshoong informaon on page 48, and Customer Service hours and contact informaon on page 51.

)39 28 E-3. Automaon (Set Up Rules For If This Then Do That) The most popular use for our Gas / Water Valve Controller is to shut o water automacally in the event that a water leak has been detected. Generally, you have two opons for this:
1. Congure an Automaon in the app. Sengs you make in the app will "tell" the valve controller to shut o the water is detected. In automaon terms, this would be wrien out
"IF a water leak is detected, THEN close the water valve." This is a simple process in our app, and if this is your rst me with a smart device and with automaon, we will explain it clearly in this secon. 2. Ulize YoLink Control to "pair" one or more water leak sensors to the valve controller, so that the water is shut o as soon as a water leak is detected. YoLink Control is a unique device-to-device protocol that allows for this to work, without internet and even without power. YoLink Control is explained on page 35 How to Set Up an Automaon (See Illustraon Next Page) Go to the Smart screen, tap Automaon Gas/Water Valve Controller can be set as either a trigger or an acon device, with two opons: turn on or turn o 29 b-1 b-2 b-3 b-4 b-5 b.

Voice Assistants Connect YoLink with third-party voice assistants to control (turn on or turn o ) or monitor the status of your devices through voice commands Tap in the upper le corner to go to My Prole Go to Sengs > Voice Assistants for the applicable voice assistant integraon guide Gas/Water Valve Controller is integrated with Alexa and Google Assistant, and is also integrated with IFTTT.com (works as trigger devices using IFTTT) 34 F. About YoLink Control YoLink Control is our unique device-to-device control technology. Using YoLink Control, YoLink devices can be controlled without the Hub or an internet connecon. (Use of YoLink Control is oponal; you can use the Automaon feature in the app OR use YoLink Control, but YoLink Control oers the benet of operaon without the Hub or internet connecon.) One device controls another, directly. A device that sends out commands is called the controller. A device that receives the commands is called the responder. Examples of a controller are a Water Leak Sensor, while examples of a responder are a Siren or a Gas/Water Valve (Controller) The Water/Gas Valve Controller can only work as the responder of YoLink Control and can only set up YoLink Control with YS7903-UC Water Leak Sensor and YS7904-UC Water Leak Sensor 2 F-1.

1. Device is oine
- If valve is not connected to the cloud, press the SET buon on Gas/Water Valve Controller once
- If Hub is oine, reconnect the Hub to the Internet and press the SET buon on Gas/Water Valve Controller once
- If Hub is not on, power on the Hub again and press the SET buon on Gas/Water Valve Controller once
- If valve is out of range with Hub, relocang the Hub may be required
- For a device with low-baery indicators or alerts or if the condion of the baeries is in queson, replace the baeries with four premium AA alkaline baeries 2. Timer does not run
- The condion of the baeries is in queson. Replace the baeries with four premium AA alkaline baeries. Press the SET buon once to open/close the valve, also you can open/close the valve via YoLink app or set a new mer. (When you add a reseng/one-me-use mer this will need to be amended with that new informaon.) 3. Other issues, contact customer service, 1-949-825-5958 (M-F 9am - 5pm PST) or email 24/7 at service@yosmart.com 48 Warning 4 Please install, operate and maintain the Gas/Water Valve Controller and Manipulator
(or Motorized Valve) only as outlined in this manual. Improper use may damage the unit and/or void the warranty Do not install or use the controller and manipulator outside of the temperature and humidity range listed in the Environmental secon in Specicaons, on page 2-47. Lithium non-rechargeable baeries, operang in a wider temperature range , are recommended for applicaons on the hoer or colder end of the controller's operang range (device environmental limitaon can be extended to the range of -4F - 176F (-20C - 80C)) While the controller is rainproof, to ensure opmal operaon and lifeme of the controller, installing the controller with overhead protecon from weather is suggested. Do not immerse the controller or allow it to be immersed in water D o n o t i n s t a l l o r u s e t h e c o n t ro l l e r a n d m a n i p u l a t o r w h e re i t w i l l b e s u b j e c t e d t o h i g h t e m p e ra t u re s a n d /o r o p e n a m e I n s t a l l o r u s e t h e c o n t r o l l e r a n d m a n i p u l a t o r ( o r m o t o r i ze d v a l v e ) o n l y i n c l e a n e n v i r o n m e n t s .

Do not use strong chemicals or detergents, which may discolor or damage the exterior and/or damage the electronics, voiding the warranty Do not install or use the controller and manipulator where it will be subjected to physical impacts and/or strong vibraon. Physical damage is not covered by the warranty 49 Power the controller only with four AA baeries (see below, regarding baeries) Use only new, name brand, alkaline non-rechargeable AA baeries Do not use rechargeable baeries Do not use zinc blend baeries Do not mix new and old baeries Do not puncture or damage baeries. Leakage can cause harm on skin contact, and is toxic if ingested Do not dispose of baeries in re as they may explode! Please follow local baery disposal procedures To avoid damaging the controller, if storing the controller for an extended period, remove the baeries Please contact Customer Service before aempng to repair, disassemble or modify the device, any of which can void the warranty and permanently damage the device 50 If you have any dicules installing or using your Gas/Water Valve Controller, please contact our Customer Service department during business hours:
