Solution(s)
This condition is normal. Ensure that the heater capacity does not exceed the
thermostat's maximum load.
Correct it if any of the following situations exists:
• The thermostat is exposed to an air draft.
• The sticker on the thermostat's screen has not been removed.
• The thermostat is located near or above a heat source such as a light dimmer
The time is not yet set or the thermostat was without power for more than 5
hours.
• Ensure the thermostat is in Automatic mode.
• Check the clock and the schedule. If the thermostat is configured for
12-hour format, ensure that PM appears on the screen when afternoon times
are displayed.
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.
