Activate the Fresh Air Feature for Quantum Fresh High-Wall SystemsUpdated 9 days ago

Introduction

This article explains how to activate the Fresh Air feature for Quantum Fresh (WYT-FA) High-Wall systems.

This function works by drawing fresh air from the outside atmosphere, filtering it, and then depositing it into the room. This lowers the overall CO² concentration and prevents stale air. 

This feature is available in Cooling, Heating, Fan, or Auto mode. If the indoor unit displays the "CL" code, replace the filter with a clean one and hold the button for more than 5 seconds to clear the code. 

Steps

1. Press the "FRESH AIR" button and select the desired fresh air fan speed. The cycle goes Auto > Low > Mid > High > Off.
