Anti-frost control activated — RUN LED flashes 8 times, TIMER LED flashes 5 times

What does 85 mean?

The anti-frost control has activated, causing the compressor to stop during cooling operation. This is often a normal protective function when the outdoor temperature drops very low (e.g., –28°C or lower for 40 minutes during heating operation).

• Very low outdoor ambient temperatures
• Accumulation of ice/frost on the outdoor coil
• Unit operating in conditions requiring anti-frost protection

Click steps to track your progress.

1. 1

   Allow the unit to complete its automatic anti-frost cycle; this is often a normal operation in cold conditions.

2. 2

   Check the outdoor ambient temperature to ensure it's not excessively low.

3. 3

   Ensure the outdoor unit is not obstructed by snow or ice, which could hinder proper airflow and heat exchange.

4. 4

   If the unit frequently enters anti-frost mode in moderate temperatures, consult a professional.
