Water heater frequently short cycles, turning on and off rapidly.

Safety: Ensure the system is cool before adjusting valves or bleeding radiators.

Steps:

• Check thermostat settings: Avoid setting the room thermostat too high or too low; moderate settings reduce cycling.
• Open radiators: Ensure enough radiators or heat emitters are open to absorb the heater's output.
• Adjust output (if available): Some Biasi models allow maximum output adjustment in the user menu. Reduce the maximum heating output if short cycling occurs.
• Bleed system: Remove air from radiators to improve heat transfer.

Note: Persistent short cycling may indicate sensor or control issues that require professional diagnosis.
