Description
Overview
The Tosot Cosmo 36,000 BTU ceiling cassette mini split is a complete single-zone heat pump system: indoor unit, inverter outdoor unit, remote and installation package. It is rated at 21 SEER2 and 8.5 HSPF2, runs on 208/230V single-phase power and uses R32 refrigerant.
Ceiling cassettes sit flush in a drop ceiling and spread air in several directions, which suits open offices, retail space, restaurants and large living areas. This system is sized for up to about 1,800 sq. ft.

Performance & Efficiency
Rated capacity is 33,600 BTU/h cooling and 34,000 BTU/h heating, with an EER/COP of 3.2 / 3.65 W/W. The inverter compressor ramps up quickly to reach the setpoint, then slows down to hold it, which avoids the on/off cycling of single-speed equipment and cuts power use. The outdoor unit is rated to operate from -13 – 122°F.
Comfort & Control
Every indoor unit includes a wireless remote, and the TOSOT+ app adds Wi-Fi control, scheduling and voice control through Alexa or Google Home. Sleep, quiet and turbo modes, auto restart after a power outage and a dehumidification (dry) mode are built in.
