The Oterra wall mounted unit is Daikin's most economical mini-split unit, but even with its low price-tag it still gets the job done.

If you're looking to create your ideal temperature and humidity in your living space, the Oterra is a great choice. Backed by a twelve year limited parts warranty, you can rest assured that your Oterra mini-split will run for years to come, and if anything goes wrong on the machine, Daikin will make it right.

Equipped with smart inverter technology, the Oterra provides excellent heating and cooling comfort while reducing your energy consumption by thirty percent or more (compared to traditional fixed-speed ducted systems). It accomplishes this by minimizing fluctuations in temperature. These fluctuations on other heating and cooling systems can account for unexpectedly high energy bills. The Oterra is very efficient all year round, while also using less energy than other HVAC systems. The smart inverter technology adjusts the compressor's speed while eliminating wasted operation by controlling the motor speed. It consistently does this, keeping your space at the ideal temperature without getting too hot or too cold.

The Oterra is an innovative and discreet unit that mounts unobtrusively on the wall. It is quiet, reliable and easy to control. One can control with the DKN Cloud app. Using the app can save you energy if you forgot to turn the unit off before you left. One can also use the app to get their living space to a cozy temperature while on the road before arriving. The unit is also controllable with a thermostat, and the Oterra is compatible with the One Touch Smart Thermostat and the Daikin One Lite connected thermostat.

If you're looking for a cost-saving solution for your living space, the Oterra might be the right heat pump system for you. Installation is simple, but it is recommended to have a professional installation, since handling of refrigerant is required.

The Oterra is ideal for:

  • Rooms where you do not want to take up any floor space

  • Renovations, new constructions and remodels

  • Sun rooms

  • Attics

  • Basements

  • Hot or cold rooms

  • Ceiling voids or attics that do not allow for a duct run option

  • Single room enhancements

  • Additions

  • Spaces that require additional heating or cooling.

If you're not looking to heat your space, you can save money by purchasing a "Cooling only" model. The Oterra is designed to not blow heat and cold air directly upon the people inside, but circulates it throughout the room. The Oterra has a quick warming function. This stops the unit from pumping liquid refrigerant in low-ambient conditions.

The unit has an anti-corrosion treatment on the heat exchanger. This can add extra time to the overall lifespan of the unit. The Oterra also has an automatic defrost mode. A sensor on the device automatically defrosts the outdoor heat exchanger when necessary. This ensures you will have optimum performance while heating.

The drain pan included with the Oterra has an improved design with sixteen holes that allow condensation to effectively drain. This results in higher efficiency when heating in low ambient temperatures. The unit has blue fin protection, meaning that the hydrophilic coated fin easily moves the condensation buildup to the drain-pan, resulting in a cleaner unit with a longer lifespan. The redesigned drain pan is easy to remove, and so is the blower wheel and indoor fan motor when the unit needs to be maintained.

The Oterra uses R-32 refrigerant, which is more eco-friendly than R-410A. Blended refrigerants can change composition, making it so that you cannot top off or clean and reuse on site. But with R-32 refrigerant one is able to top it off and clean and reuse on-site. Also R-32 does not need to be changed as often than certain systems, and emissions can be up to 80 percent lower than comparable R-410A systems. Daikin has the aim of keeping their units more eco-friendly, and the Oterra, with its lower GWP R-32 refrigerant aligns with the goals of decarbonization and electrification with cleaner energy. It is an effective heating unit which provides ample heating and cooling comfort while offsetting older and more efficient sources of heat using fossil fuels.

Another neat feature that the Oterra has is the Eco+ Mode. This feature limits the air conditioner's energy consumption by up to seventy percent of its capacity. This is another way that the Oterra can save you extra money on your power bill. The speed on the air conditioner's compressor is slowed down and the fan runs continuously, circulating the air.

The Oterra is a fantastic choice for those on a budget who are looking to get a Daikin mini-split. It has many of the same features as the other more expensive Daikin models at a cheaper price. This mini-split is highly recommended.
