Thermostat randomly resets to factory settings, losing Wi‑Fi and schedule configuration.

Safety: Ensure power is off before adjusting the housing or backplate.

• Step 1 – Check power stability:
  • Verify that the power supply is not intermittently dropping (loose connections, failing transformer).
• Step 2 – Inspect reset button area:
  • Ensure the thermostat cover is correctly fitted and not pressing the reset button unintentionally.
• Step 3 – Firmware update:
  • Update to the latest firmware via app.
• Step 4 – If resets continue:
  • Internal memory may be failing; replace the Protherm smart thermostat.
