ClimateMaster PTAC is a packaged terminal air conditioner with both cooling and heating modes that is designed to be installed through the wall. It is an individual zone air conditioner, meaning it can cool or heat a single room independently of the rest of the house. The PTAC is available in two cabinet styles, the SF and MP models. The SF model consists of three sections which are individually packaged, while the MP model consists of four sections. Both models have a self-contained adjustable thermostat with a heat anticipating, discharge feedback feature.
