Thermostat does not follow programmed schedule; temperature holds at one setting.

Steps:

• Check hold status: On the main screen, see if 'Hold' or 'Permanent Hold' is active. Cancel hold to resume schedule.
• Verify schedule is enabled: In the thermostat menu, ensure scheduling is turned on and the correct schedule type (weekday/weekend, 7-day) is selected.
• Confirm date/time: Make sure the thermostat's clock and day of week are correct.
• Recreate schedule: Delete and re-enter schedule periods via the thermostat or Rheem app.
• If schedule still not followed: Perform a factory reset and reconfigure. Persistent issues may indicate a faulty thermostat.
