The Z2 error is one of the most common errors in a boiler. It occurs when there is an issue with the temperature sensor meant to monitor the water temperature and regulate it to optimal levels.
When this sensor fails, it will register the system’s temperature as being hotter than it is. This causes a fault code to be generated and sent to the boiler’s control board, activating an alarm.
