The AUBE Technologies TH104PLUS thermostat operates in several modes:

  • Automatic (Auto) Mode: Adjusts temperature based on a programmed schedule with up to 4 periods per day.
  • Manual (Man) Mode: Maintains a constant temperature set manually.
  • Away Mode: Sets a lower, pre-determined temperature for energy saving during extended absences.
  • Standby Mode: Disables heating but provides frost protection, activating heat only if the room temperature drops below 5°C (41°F).

The thermostat features programmable schedules for weekdays and weekends, temporary temperature override, and advanced settings for customization.

Thermostat is hot. This condition is normal. Ensure that the heater capacity does not exceed the thermostat's maximum load.
Wrong temperature is displayed. Correct it if any of the following situations exists:
  • The thermostat is exposed to an air draft.
  • The thermostat is located near or above a heat source such as a light dimmer.
Wrong time is displayed. The thermostat was without power for more than 5 hours.
Temperature does not change according to the programmed schedule. Check that the thermostat is in Automatic mode. Check the schedule and clock settings. If the thermostat is configured in 12-hour format, ensure that PM appears on the screen when afternoon times are displayed.
LP appears on the screen or the screen is blank despite there is no power outage. The thermal circuit breaker in the heater is opened. This can happen if the heater is obstructed by furniture or curtain and has overheated, or if the thermal circuit breaker is defective or too sensitive.
The settings cannot be changed. The settings are locked (see page 13).
