The other wire of each valve goes to an individual zone port. ● If you have a master or pump start relay wire, you can insert it into any zone port -- OpenSprinkler uses software defined master / pump zone so you can dedicate any zone as a master zone. - Page 5 A sensor should be connected between SN1 and GND (or SN2 and GND if using a second sensor). Do NOT plug in any sensor wire to COM -- OpenSprinkler uses GND (not COM) as common for sensors. For additional details on how to connect sensors (e.g. rain or flow sensor), refer to later sections in this manual.

RF signal code from your remote power sockets. Once the code is set, whenever this zone is turned on/off, OpenSprinkler will send the on/off code through RF transmitter to remotely switch the power socket. This allows your OpenSprinkler to control powerline devices, such as Christmas lights, heaters, pumps, etc. -

Cloud Synced Attributes: once you log in to opensprinkler.com in the UI/app (through sidebar menu), cloud-synced attributes will become available, including station photos and notes. You can take a custom photo for each station by using the OpenSprinkler mobile app. - Page 11 Sensor Installation: all sensors described below have two wires (except the 3-wire flow sensor). To install Sensor1: insert the two wires to the sensor terminals. On OpenSprinkler v3, insert the two wires to SN1 and GND. To install a second sensor, insert the two wires to SN2 and GND.
- Page 12 ○ Flow sensors with 3 wires and runs on 5V can also be used with OpenSprinkler. In this case, insert the ground wire (typically black colored) GND, 5V wire (typically red colored) to VIN, and the sensor wire (typically yellow) to SN1.

(due to the water time being too short). 7.3 Zone's Sequential Attribute OpenSprinkler supports running multiple zones in sequence (one after another) or parallel (concurrently). This can be set using each zone's Sequential attribute. Zones that have the Sequential attribute turned on will be automatically serialized. For example, if zones 1, 2, 3 are sequential, the controller will make sure only one of them is running at any given time. -

ANT pin on the transmitter. The wire can be straight or curled like shown in the picture below. ● OpenSprinkler v3 has a built-in receptacle pin header for the RF transmitter. You can directly plug in an RF transmitter (3-pin) on the top side. The orientation is such that it's facing up. See the Hardware Interface diagram for the locations of the RF pin header. - Page 17 800mA continuous per zone (AC); 2A continuous per zone (DC).
