Description

One outdoor unit supports up to four wall-mounted indoor units (9K/12K/18K/24K BTU models), allowing independent temperature and mode control for different rooms. The advanced inverter compressor fine-tunes performance for whisper-quiet operation, producing sound levels as low as 22 dB to 36 dB, making it ideal for bedrooms, home offices, nurseries, and other quiet areas where noise matters. The dehumidification function removes excess moisture from the air, helping reduce mold growth and musty odors, and improves indoor air quality. It creates a fresher and more comfortable space, making living space more enjoyable year-round. TOSOT Cosmo series multi-zone mini-split system offers a wide range of configurations to suit different needs. Suitable for multi-room temperature control.

    • Great Multi Zone Mini Splits!
Set name: Tri Zone: 36,000 BTU (12K+12K+12K)
So far so good! These seem to be very well built units. They’re doing a great job cooling in the summer,and having them for back up heat in the winter is also terrific. I did the installation which wasn’t difficult, and had a HVAC friend come by and do the final connection to the unit and startup.

Review Image by BunsoLyn18
I have this since summer, at summer time we are happy using it because it helps a lot to make my 3 rooms cold, but now that is winter the problem is you can’t used heater while other room is using air conditioner it gives you error, and even we reset still give us error so I need to wait until tomorrow and will work. Installing it is not hard because we got someone who knows how to install this kind of product, the energy is not bad, I don't think our bill went up high when we install this. It didn’t take so much space on our wall. ... show more

Very happy with this unit. I heat and cool two separate rooms. A 950 ft shop with 12' ceilings and a 450 sq ft apartment. Both rooms are well insulated. I was using a wood stove for the shop. This unit was so efficient I can heat both for the price of just heating the apartment with a ptac unit.

I don't know why I waited so long. The A/C dispensing units work better than any home unit I have ever had. I would recommend this product over-and-over-again. I can control the temperature almost instantly, it's incredible!!

This company does not supply on the phone tech support it’s through email and it takes forever. On top of that they DO NOT supply repair parts. If something fails, you will need the entire unit. Again they don’t parts at all.. these cannot be repaired. Buy a Senville or another brand that offers parts and tech support. Tosot fails at both of these. Don’t buy. ... show more
