2A7KU-S-W-1Smart water timer

（Zigbee） Smart Water Valve User Manual www.sainlogic.com ●
Smart water valve Remote operation: remote control of mobile APP anytime and anywhere, manual control of field devices, and timing control of APP Signal distance: the open distance between gateway and smart water valve is ≤50 meters Battery:4*AA alkaline dry batteries are used. Protection grade: IP66. Smart water valve can be installed and used outdoors. 1. One gateway can be connected with 8 smart water valves. 2. The open distance from the gateway to the smart water valve is ≤50 meters, and the partition wall distance is ≤20 meters (determined according to the actual installation environment). 3. Zigbee signal cannot be relayed and jumped through smart water valve. 4. After setting the timing, if the smart water valve is offline, it will be watered according to the timing program. 5. Operational requirements of water flowmeter: the water flow rate is at least 2L/ min, and the water flow is too small to drive the flowmeter to work. There will be a false alarm of "water shortage warning". 6. Statistics will be recorded only when the smart water valve is online for historical records. 7. Water shortage reminder: When the water valve is opened and there is no water, the water shortage warning will be prompted after 15 seconds in the connected state.
