Yes, the Mark 3 has a heating mode. However, it is designed as a supplementary feature rather than a primary heating solution. It is only effective above 50°F (10°C).
We recommend first using your primary heating system to raise the room temperature to your desired level, then using the Mark 3's heating mode to help maintain that temperature.
During cooling, the front releases cold air and the rear expels warm air.
The Mark 3 is designed for personal and small-area cooling (100–150 sq. ft.). It focuses on spot cooling or flexible use in compact spaces—ideal for outdoor or portable setups.
The "Care Mode" uses a PI (Proportional-Integral) algorithm to quickly adjust the compressor speed, helping the outlet air temperature match your desired setting faster. It provides rapid, targeted comfort by quickly reaching your preferred temperature.
Yes. When connected to a wall outlet via the included AC adapter, it can run continuously without a battery.
