Your Valve Controller is unresponsive if:
1. Pressing the grey button on your unit does not open/close your valve
2. Pressing and holding the grey button does not result in the unit beeping
3. Power cycling (unplug/plug it back in while its battery backup is removed) the Controller does not change its unresponsive status
If your Valve Controller is unresponsive, please reach out to us at firstname.lastname@example.org with your proof of purchase.
