Ductless Extra Low Temp Heating ASU12RLS2 Air Conditioner

As much as half of the energy used in your home goes to heating and cooling. So making smart decisions about a home’s HVAC system can have a big effect on utility bills — and comfort. Systems 9RLS2H, 12RLS2H and 15RLS2H are among the most efficient mini-splits in North America, with Seasonal Energy Efficiency Ratings of up to 27.2-SEER.
The RLS2H systems are packed with features specifically created to save you money – like Energy Saving Program, or ESP, a programmable remote control and inverter

Product Specifications

Powerful Heating Down to -15°F Outdoor Temperatures

Heating capacity at low outdoor temperatures was improved by adopting a large heat exchanger and a high capacity compressor. Rated heating capacity is maintained up to 20°F. This new model can operate down to -15°F.

Base Freeze Prevention

RLS2H outdoor models are equipped with a base heater that prevents condensate from freezing. The cultivated base design discharges melted water through many holes. Without a heater, freezing condensate can cause noise, damage to fan blade, condenser, and system performance.

Energy Saving Program (ESP)

Halcyon system knows how to save you money even when you forget. If you leave the room without turning the unit off, ESP knows that you left and 20 minutes later, set temperature is increased by 4°F when cooling and reduced by 8°F when heating. When you come back to the room, it returns to previous operating mode. This prevents wasteful operation to save energy without you having to think about it.

Programmable Remote

Weekly timer can be easily set by wireless remote controller. ON, OFF can be set up to 4 times in one day and up to 28 times in one week. For other modes, program timer and sleep timer can also be selected by pushing a single button.

Powerful Heating

Heating capacity at low outdoor temperatures was improved by adopting a large heat exchanger and a high capacity compressor. Rated heating capacity is maintained up to 20°F. This new model can operate down to -5°F.

World Class Performance

Since mini splits have little to no ducting, they forego those energy losses typically associated central forced-air systems. Duct losses can easily account for more than 30% of energy consumption, especially if the ducts are not sealed tight or in an unconditioned space such as an attic or crawlspace. With ratings as high as 27.2-SEER (Seasonal Energy Efficiency Ratio), systems 9RLS2, 12RLS2 and 15RLS2 are among the highest rated efficiency equipment available anywhere!

Inverter Technology

Through advanced technology, Inverter air conditioners are more economical to operate and quieter to run than conventional units. They can handle greater extremes in temperature, are smoother and more stable in operation, and reach the desired temperature more quickly than conventional air conditioners.The Inverter component allows the outdoor unit to vary its speed and output to match the required capacity of the indoor unit. Thus, the Inverter model can achieve 30% more operating efficiency than conventional models and therefore, is much less expensive to run.

Quiet Operation

Ductless heat pumps and air conditioners are comprised of an indoor and outdoor unit, allowing for a peaceful inside environment by enabling components like compressors and motors outdoors to be installed outside.

I recently had my old 50 Gallon storage tank replaced with Bosch T9800 Tankless water heater. This is indeed a great product and has a lot to offer as far as the hot water supply is concerned which is unlimited. This is my first experience using a tankless and I am glad that I chose Bosch brand. - Todd From Markham

A friend of mine recommended me to buy Bosch brand tankless water heater as I was already looking for a tankless and did a lot of research. Eventually I ended up buying Bosch T9800 SE 166 which was a perfect match for my requirement. I must say that Bosch brand appliances are very much reliable and innovative. - Daniel From Stoney Creek
