The most common question we receive concerning INSTEON Water Shutoff Valves is, "My valve starts to open then immediately closes again. I can't get my water to stay on. Do I have a bad valve or is the I/OLinc defective?"In almost all cases, both the valve and the I/OLinc are both working fine. The problem is only an incorrectly set Output Relay Mode option. The Model 2450 I/OLinc has 4 Output Relay modes, (Latching, Momentary A, Momentary B, & Momentary C). The default setting is Latching, however, the mode can be inadvertently changed by pressing & holding the SET button on the side of the I/OLinc for more than 3 seconds, 3 consecutive times, within a 4 minute window. If the I/OLinc has been reset to a Momentary option, the valve will open and immediately close again, (or start to close and immediately open again depending on how the valve is wired to the I/OLinc).
This issue is not isolated to only water valves. Any low voltage application that uses the I/OLinc can display similar characteristics (e.g. curtains, gas fireplaces, etc.) There are three common ways to restore your I/OLinc to the Latching Mode:
- Perform a Factory Reset by unplugging the I/OLinc, wait 5 seconds, press and hold the SET button, plug the I/OLinc back into the outlet, continue to hold the Set button until the long beep stops, Release the Set Button. Warning: This procedure will erase any linking information in the I/OLinc and will need to be relinked.
- Or if you are using an INSTEON HUB, open the App and select the I/OLinc. Open Settings and change the Output Relay Mode option to Latching, then Save your settings.
- Or press the SET button on the side of the I/OLinc for 3 seconds until it beeps (Status LED will begin blinking). Press the SET button a second time for 3 seconds until it beeps again (Status LED will continue blinking). Press the SET button a third time for 3 seconds until it beeps again (Status LED will stop blinking and turn on solid). The Output Relay option will rotate to the next mode (e.g Momentary A to Momentary B) Test for proper operation. If the Output Relay is still not Latching, repeat the procedure to rotate to the next mode, (i.e.Momentary C to Latching).
