<h3 class="sub-tit">Does CH05 occur immediately after installing a new product, or installing a used product at
            other place?</h3>
        <p>
            CH05 code is a function detecting abnormal communication between the indoor unit and the outdoor unit of an
            inverter air-conditioner.<br>
            If same symptom persists after power resetting, have it checked by a service technician.
        </p>        
<h3 class="sub-tit">Does CH05 occur during running the product, not immediately after installing?</h3>
        <p>
            Error code of the product indicates that temporary error may take place because of unstable power supply, or
            other electric causes.<br>
            Turn the power code or trip circuit breaker of the product off, and then reset the breaker about 5 minutes
            later.<br>
            If same symptom persists after power resetting, have it checked by a service technician.
        </p>        
<h3 class="sub-tit">Is the product for exhibition or demonstration?</h3>
        <p>
            The product for exhibition or demonstration is used for the purpose of demonstration without connection
            between the indoor and the outdoor unit, and may indicate abnormal communication error between the
            units.<br>
            Use [Demonstration Mode] when you demonstrate the product at your store.<br>
            Demonstration Mode has a function of demonstrating display operation and lighting [Cleanness indicator]
            colors of the exhibited product.
