Other symbols on Fujitsu and their meaning

This symbol on your thermostat may mean your HVAC system is in Defrost or Oil recovery mode. It may also indicate a time off delay

What is Defrost Mode?

When it’s cold outside and the humidity is high, frost can build up on the outdoor unit of your air conditioner, which can reduce its efficiency. 

Luckily, your Fujitsu thermostat has a defrost mode to tackle this issue. When frost is detected, the thermostat automatically initiates a defrost cycle. 

During this cycle, the indoor fan will temporarily shut down, and you’ll see this displayed on the remote controller.

The defrost cycle typically lasts anywhere from 4 to 15 minutes, ensuring that the frost melts away and restores optimal performance to your air conditioner.

What is Oil Recovery Mode?

In multi-type air conditioners, there’s another important mode called oil recovery. During the oil recovery cycle, the indoor fan will also temporarily shut down, and you’ll see this displayed on the remote controller. 

This cycle typically lasts a maximum of 5 minutes. It allows the system to recover and redistribute any oil in the refrigerant lines, ensuring smooth operation and efficient cooling.

 Once the oil recovery cycle is complete, your air conditioner will start up again, ready to keep you comfortable.

By keeping the temperature a little closer to the outdoor conditions, the system reduces its energy consumption without sacrificing too much on your comfort. 

So, the Economy mode is a smart way to cut down on energy usage and save some bucks while still maintaining a reasonably comfortable indoor environment. 

It’s all about finding that sweet spot between efficiency and comfort!

 The best part is, you don’t have to lift a finger or worry about adjusting anything. The system does it all for you.

Auto mode also takes care of the fan speed. It knows just how much airflow you need to stay comfortable, so it adjusts the fan speed accordingly. No more feeling too stuffy or having a weak breeze.

With auto mode, your Fujitsu mini-split is like a smart system that keeps you cozy without any hassle. It’s a hands-free way to enjoy the perfect temperature in your space.
