Boiler frequently goes into anti-cycling or anti-freeze mode even when not required

Safety: No direct hazard, but may waste energy.

User checks:

• Thermostat location: Ensure the room thermostat or remote control is not near heat sources or in direct sunlight.
• Program settings: Review heating schedules and anti-freeze settings on the Fondital controller.

Technician actions:

• Check and, if necessary, relocate the room thermostat or external sensor.
• Verify and adjust PCB parameters (anti-cycling time, anti-freeze thresholds) according to Fondital documentation.
• Test NTC sensors for drift and replace if out of tolerance.
