Description
Overview
The Tosot Cosmo 34,000 BTU concealed ducted mini split is a complete single-zone heat pump system: indoor unit, inverter outdoor unit, remote and installation package. It is rated at 20 SEER2 and 8.5 HSPF2, runs on 208/230V single-phase power and uses R32 refrigerant.
Concealed ducted units hide above the ceiling or in a closet and feed several rooms through short duct runs, so only the grilles are visible. This system is sized for up to about 1,800 sq. ft.
Key Features
- Commercial-grade airflow: High-CFM indoor sections for large rooms, open plans, shops and offices.
- DC inverter compressor: Smooth, efficient capacity control with R32 refrigerant.
- Wi-Fi control: TOSOT+ app control and scheduling.
- Built-in safety: Refrigerant leak detection and condensate overflow protection where equipped.
- Wide operating range: Reliable cooling and heating across extreme outdoor temperatures.
- Up to 20 SEER2 energy efficiency
- High static pressure range (0–275 Pa) for extended duct runs
- Ultra-slim design saves space in tight installations
- Built-in auto-drainage system for hassle-free condensate removal
- Integrated float switch for overflow protection
Performance & Efficiency
Rated capacity is 33,600 BTU/h cooling and 34,000 BTU/h heating, with an EER/COP of 3.51 / 3.73 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.
