My controller has been working fine and suddenly stopped regulating the pressure, everything seems ok with the controller?
If no network conditions have changed it could be a fault on the controller. Place the controller in “Manual” mode and make it try and achieve a high or low pressure. You should be able to hear the solenoids clicking (or place your hand on the solenoid box and feel the vibration) which means the controller is trying to work. If this is not present your controller will need servicing.
