Firstly, please rule out any wiring issues with the controller.
Gently tug on all wires to ensure there are no loose connections.If a rain sensor is NOT connected, make sure it is not enabled in the App under "Settings", "Controller Settings", "Sensor". Make sure the sensor port is NOT checked.If a master valve OR pump start relay is connected, enable the corresponding port under "Settings","Controller Settings","Advanced Wiring (M Terminal)".If the issue only affects one zone, try moving the wire from that terminal to another working terminal and test it there.
If the wiring is correct, please check the Standby Mode, Water Delay and Skip
If any of these features are enabled, you will see a white horizontal line and numbers with a line through them at the top of the calendar in the Schedules interface, or the forecast view in the Home page. Please check if any of the three features are enabled. Try disabling them and see if the controller operates normally.
If the issue persists, check the water supply.
If there is a master valve, manually open it and run the ImoLaza device.If there is a pump, ensure it is activating and allowing water flow.Manually open a zone valve to check for water flow.
If water flows normally, rule out water supply issues. Use a voltmeter to check the voltage from the controller.
Set voltmeter to AC volts.Open an affected station, or manually trigger a cycle if multiple stations are affected.Place one probe in the COM terminal, and the other in the manually activated station, ensuring wires are inserted into terminals. You should get 24-30 AC volts.Repeat for other affected stations.
If the controller voltage is within range, test the voltage at the valve.
Ensure the controller is still active.Locate the valve box and identify the active zone.Attach voltmeter leads to two wires on the valve. You should get 24-30 AC volts.
If voltage reaches the valve, the valve may be faulty. Consult valve manufacturer.
