Delta Dore Intermittent Memory or Power Glitch

Thermostat randomly resets to factory settings, losing schedules and configuration.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose power connection, Voltage dips or surges, Failing internal memory, Firmware instability

Safety first: Isolate power before tightening terminals.

Tighten power terminals: Ensure the supply connections at the thermostat base are secure.
Surge protection: If the property experiences frequent surges, consider installing a surge protector on the heating circuit.
Firmware update: Update the thermostat and Tydom gateway firmware if updates are available.

If resets continue, the internal memory or power circuitry is likely failing and the thermostat should be replaced.
