Description
Overview
The Tosot Cosmo 9,000 BTU wall-mounted ductless mini split is a complete single-zone heat pump system: indoor unit, inverter outdoor unit, remote and installation package. It is rated at 20.5 SEER2 and 8.8 HSPF2, runs on standard 115V household power and uses R32 refrigerant.
Wall-mounted units are the most popular way to add heating and cooling to bedrooms, offices, additions, garages and other rooms without ductwork. This system is sized for up to about 450 sq. ft.
Key Features
- Full DC inverter compressor: Varies speed with the load for steady temperatures, quiet operation and lower power use.
- Blue Fin coil protection: Evaporator and condenser use deoxidized all-copper coils with Blue Fin anti-corrosion coating for long service life.
- Wi-Fi control: Control, schedule and monitor the system from anywhere with the TOSOT+ app; also works with Alexa and Google Home.
- Quiet operation: Indoor sound levels in the low 20s dB(A) on low fan, suitable for bedrooms and offices.
- R32 refrigerant: Higher efficiency and a much lower global warming potential than R-410A.
- Complete installation package: Includes a pre-flared 16 ft copper line set, signal cable and power cord, with 25 ft and 50 ft line sets available.
Performance & Efficiency
Rated capacity is 9,100 BTU/h cooling and 10,000 BTU/h heating, with an EER/COP of 3.5 / 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 – 118°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.
