Thank you for your question. This mini split system includes a handheld remote controller that can be used to control the system. It also comes with a smart controller which you can plug into your air handler. This smart controller makes your unit wi-fi enabled, thus giving you the ability to control it from your phone, Amazon Alexa or Google Assistant. Both of these methods of control allow you to turn the air handler on or off. For more assistance, please give us a call.
