Control your new Pioneer CYT cassette system by the remote, or remotely, via your iOS or Android smartphone. Set schedules, turn the system on or off, and monitor current indoor and outdoor temperatures from across the world, all conveniently from the free Pioneer Airlink app.


The Pioneer CYT series cassette offers a provision of fresh-air intake via an optional reserved port. New outdoor air can be easily brought inside to replace stale room air.

With the wide operating angle of the airflow louver, the Pioneer CYT series cassette is able to drape the room with a satisfying breeze in cooling mode, and wrap the area with cozy warmth in heating mode.

Not only are the air filters washable and re-usable, they are super easy to access. Simply detach the center grille and slide out the filter when it's time to wash. Re-insert the same way when done, so that your cassette can continue removing pollen, dust, and other allergens from the air in the room.

Every cassette includes a condensate pump that is capable of vertically lifting drainage water up to 30 inches, which can be disabled if desiring to drain via gravity instead. And if the drain pan stays full due to a clog, the system will shut itself off to prevent overflow and flash an alert code.
Pioneer Mini Splits offer a multitude of options when it comes to commanding your system.

Handheld Remote: The easy to use RC310TG remote offers quick and simple access to all of the important functions of your system (included with purchase).

Phone App: No remote, no problem. Use the tech that's already with you at all times by downloading the free Pioneer Airlink app (available out of the box).

Voice Control: Once configured, Pioneer Airlink offers integrations to various 3rd party voice control platforms like Google Assistant, Amazon Alexa, and Apple Siri.

Wired Controller: The CYT cassette is compatible with the latest wired wall-mountable controller TST-WPT-540L, for weekly programming (available sold separately).
