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 does the temperature setting affect the unit when it is set to dry mode. It seems like it "dry's" to be much cooler than the setting
The DRY mode works by making the indoor coil extra cold and slowing down the fan speed very low. This is so that it can draw out as much moisture from the air as possible.
Do the lines come flared? Or do i only have to flare them if i want a custom length?
They arrive pre-flared from factory. If you shorten them then you would need to reflare the ends.
Does this have an energy star rating? What is the average usage per month?
Yes this is Energy-Star certified.
- AHRI Estimated Yearly Operating Costs:
- Cooling: $148.00
- Heating: $505.00
What is the AHRI number for this unit?
It is 8819852, for more info see here: https://www.pdhvac.com/site/downloads/certificates/certificate_WYS024GMFI22-205.pdf
What is the lowest outdoor temperature the unit will work at when used for cooling
For COOLING mode it would be 5°F.
How many amps does the 2400 BTU draw?
This system draws 8.4A in cooling and 10.1A in heating. It requires a 20A double-pole breaker with 12 AWG wire.
Does the indoor unit have to be mounted on exterior wall?
No, it can be mounted on an interior wall. However, you would need to route the condensate drainage into a nearby sewer pipe from a kitchen or bathroom, or implement our condensate pump to route the drained condensate elsewhere.
Should this have a fusible disconnect, or is the breaker in the main panel sufficient?
Any disconnect whether fused or unfused will do, it will just act as a pullout switch for servicing. But ultimately the breaker in the circuit panel will be enough.
what is the lowest temp heat pump will work
This system will continue heating down to -13°F outside temperatures.
I purchased the WYS024GMFI22RL-16 unit and the technical brochure says it should have a minimum ampacity circuit of 15. But, the question below says it should be 20A with 12 AWG wire? Which is correct?
Either is permissible. 15A is the absolute minimum, we recommend a 20A double pole breaker with 12 AWG wire as that is typically more commonly found.
Ordered the system with a 16ft line set ,will a 10ft line set work without a problem?
That would not be a problem at all, the included pre-charge can support line lengths between 10 and 25 ft.
Will this unit work on 240 volts?
Yes, it can work on anywhere between 207~253V.
On this unit 24000 21.5 seer how many sq ft will it take care of
This is intended for spaces between 650 and 950 square feet.
How loud does the unit sounds? I am looking for a quite unit to install in a spa environment. It can not run louder then the relaxing music. Please explain!
These systems are ultra silent and barely audible. The 24K unit on low is about 35 dB, which is actually quieter than a library. You won't even believe it's on unless you put your hand over the vent to feel the air.
What size are the coolant lines, not length?
This system takes 3/8"-5/8" diameter lines.
What’s the amperage and recommended breaker size? Does this unit require a neutral wire?
This system would take a 20A double-pole breaker with 12 AWG wire. The wire would be two hots and a ground, no neutral.
What temperature does efficiency start to drop off at? For I instance at 20 degrees is it still at 100% Efficiency, whsf?
You can see the heating performance curve here.
Can this be connected to a thermostat?
There are currently no wired thermostat options available, the closest solution would be this wireless smart controller which can act as a thermostat for all intents and purposes.
What are the wifi options?
What is the max height the outdoor heat pump can be mounted? Can I mount it 3ft above the ground
The outdoor unit and indoor unit should not have a height differential greater than 16 ft.
Otherwise, mounting the outside condensing unit 3 ft off of the ground is not a problem.
