The function enables the air conditioner to automatically increase cooling or decrease heating 1°C per hour for the first two hours, then holds steady for the next 5 hours, after that it will switch off. This function maintains both energy savings and comfort at night.
Temperature compensation function eliminates the difference in temperature between the floor and ceiling by mixing the different layers of air. Consequently, the time for cooling the room is reduced, and a cold offset rising stream of warm air by stirring.
Refrigerant Leakage Detect
Indoor unit shows error code "EC" and stops automatically when refrigerant leakage is detected. This protects the compressor from high temperature damage due to refrigerant leakage.
Anti-cold Air Function
Indoor fan speed is regulated automatically from the lowest grade to the setting grade according to evaporator temperature when the unit just starts heating operation. This function can prevent cold air blowing out to avoid discomfort to the users.
- Emergency start
Low Ambient Cooling
With built-in low ambient kit or special designed PCB, outdoor fan speeds can be changed automatically according to condensation temperature. The air conditioner can run cooling operation even when the outdoor ambient temperature is down to -15°C.
Intelligent on-off technology enables Pioneer products automatically enter energy-saving mode when standby, cut energy consumption from normal 5W to 1W or 0.5W per hour which counts 80%~90% of saving.
Both left and right sides of the indoor unit are possible for outstretch of connective piping and drainage hose for easy installation.
Follow Me (Remote Thermostat)
Temperature sensor built in the remote controller will sense it’s surrounding temperature. The unit will adjust the room temperature more accurately to give you comfort.
In heating operation, the preset temperature of the air conditioner can be as low as 46°F, which keeps the room temperature steady at 46°F and prevents the house from freezing when it is unoccupied for a long time in severe cold weather.
Chassis Heating Belt
Heating belt is fitted on the base plate of the outdoor unit to prevent defrosting water accumulation, which improves heat transfer efficiency.
High Density Filter
Compared with ordinary dust filter, the anti-dust effect of this high density filter can increase more than 50%, it can clean dust, pollen up to 80%.
With the Wireless control, you can easily turn off each indoor unit that it is paired, outside your home via your smart phone. Furthermore, you can turn it on before you come back.

QUESTIONS & ANSWERSAsk a Question
how much clearance is required above the wall unit
We recommend 4-6 inches, 6 would be best.
What size line set is needed for this unit?
This would take 1/4"-1/2" diameter lines.
Will a portable 3500 watt continuous generator be able to power your energy star 12,000 btu 21.5 seer mini split during power outages?
Most certainly. This unit draws a peak of 1.5kW (average is about half that) so a 3.5kW generator should have no issue keeping the unit running even in full demand.
what size area will this unit handle?
For typical scenarios we recommend this unit for managing between 200 and 450 square feet.
The section on refrigerant says, R410A Pre-Charged Outdoor Unit, accommodating refrigerant line lengths up to 25 ft. per circuit. Does this mean the line set can only be 25 ft.? I see an option for a 50 ft. installation kit. How does that work?
The way it works is that the outdoor condensing unit is pre-charged with R410a to support line lengths up to 25 ft long. You can have a line up to 80 ft long, but for longer than 25' lineset runs, you will need to top off additional refrigerant during installation in order to rebalance the contained charge.
How many lbs of R410 is in this unit?
This system is factory preloaded with 40.60 ounces of R410a.
what size wire to run to box??
This takes a 20A breaker and 12 AWG wire.
What is minimum temperature for operational heating of this unit?
This particular system can HEAT down to -13°F outside temperatures.
What is the amp draw for this unit?
This particular system is rated 8.4A in cooling mode and 9.8 in heating mode.
Does this have the anti mildew option?
There is a "self-clean" feature to dry the coils, and the blower wheel is treated with an anti-mildew coating.
Are these two model numbers for the same unit. WS012AMFI22HLE vs WS012AMFI22RL I'm looking to purchase the inverter ++ unit and found these two model numbers. thank you
WS012AMFI22RL is a combination SKU entailing the full set of both indoor unit (WS012AMFI22HLE) and outdoor unit (YN012AMFI22RPE).
Hi there, I have a 12k BTU system I just recieved! I want to install it in my basement. Is there a way to drain the condensation vertically? Thanks.
You would need to add a condensate pump to pump it upwards. SKU: CP-RE-MWP-06
How much clearance is needed at back of outside unit to another surface?
It would need 12 inches of clearance behind when ground-mounted and 3 inches when wall-mounted.
