The measured electrical service at my breaker panel is 240VAC, 60Hz, single phase. Your specifications indicate 208-230V. Will your unit work on 240V?

Yes it will be suitable for any service between 207~253V.

Will it be ok to use a dedicated 20 amp breaker and 12/2 wire, also do you need a disconnect by the outside unit?

You would need a 15A double pole breaker for this system. Either 14 or 12 AWG would be fine. A disconnect is optional but highly recommended.

What size breaker with this unit take?

The 12K 230V system takes a 15A double-pole breaker with 14 AWG wire. The wire type is 3 conductor, for L1/L2/GND.

What is output heating and cooling at lowest output?

The lowest cooling output is 3700 BTU, and 3500 BTU for heating. For full specs, see here.

Is it possible to shut off the temperature display on the front of the unit? It may to bright for sleeping?

Absolutely, just hit the LED button on your remote and it will turn the display off.

What size are the line set connectors for 12k unit

This system takes 1/4" and 1/2" diameter sized lines.

How many square footage does this cover?

This is recommended to be used for spaces between 200 and 450 square feet in typical scenarios.

My current outdoor a/c compressor has a double pole 30 amp breaker, would i be able to run 2 of these units off that single breaker?

Each condenser unit needs its own dedicated breaker. As such, you would need two breakers for two systems, or keep that 30A and put a multi-zone system on it.

What size hole is needed for refrigerant and communication lines?

It would be a 2.5" diameter hole.

can this unit be controlled by wifi

Yes, you would just need to incorporate this device.

Did I read correctly, the provided electrical cable that comes with the line set for communication between the inside and outside units is the only power wire that will be needed for the operation on the inside unit. ?

That is correct. Outdoor unit powers indoor unit via the signal cable.

What are the dimensions of the indoor unit?

Net Dimensions (WDH): 31.57 x 7.44 x 11.69 Inches

Is this the inverter+ or ++?

This is an Inverter+. The Inverter++ line would be found here.

How many sq feet is this unit rated for?

For general applications, this system is intended for spaces sized between 200 and 450 square feet.

What size breaker do I need for 220 volt 12000btu unit for 500 sf

This particular unit would take a 15A double pole breaker.

what is cost of wall mounting brackets for outside unit for this system

Those are available here.

I know this comes with a wall-mount kit for the indoor unit, but does it come with a wall mount kit for the outdoor unit?

The wall mounting brackets for the outside unit are sold separately as an accessory and are available for purchase here or here.

this unit use regular 120 v. or 220v?

This particular system uses 208/230V and not 110/120V. The 110/120V version is located here.

Does wall unit come with mounting brackets?

Yes the indoor wall handler comes with the mounting bracket pre-attached on the back.

Can this system be thermostat controlled to cycle on and off

It can be programmed to come off once set temperature is hit like an on/off unit would, though this would decrease efficiency.

Is a there a filter on this unit that needs to be changed from time to time? Thanks!

Does the blower cycle on and off as needed when the unit is on?

This is not an on/off system, it is an inverter so it stays on but adjusts down fan speed to fight the heat loss and maintain the set temperature. This makes it much more energy efficient than turning on and off all the time. You are able to program the unit to turn off when set temperature is reached, if desired.

Can more than one mini split be run from the same condenser?

This would require a multi-zone solution: multi-zone

Does this heating / cooling system require access to natural gas lines, or can it be run on electric only?

This is a heat pump that uses refrigerant and runs on electricity, it cannot and does not require gas.

It says 45deree heating standard feature what does that mean what is the temp when heat pump stops?

This is referring to freeze-protection (FP) mode. It is a "vacation mode" meant to protect the lines from freezing by maintaining a 46°F heating output. This particular system will heat and cool down to +5°F outside temperatures.
You can also consider our Inverter++ line, which HEATS down to -13°F.

do you need a pro to make the connections and draw a vacuum?

It is not required but recommended to have a tech come to pull a vacuum, check pressures, and release the pre-charged refrigerant. It can also be DIY with the use of special tools such as vacuuum pump and pressure gauges.

Does the mini split model WYS012GMFI19RL-16 come with a pad, cooper line set and communication cable?

The "-16" at the end indicates that it will come with a 16 ft. copper lineset and 16 ft. communication cable. This can be modified on the dropdown menu, above the "add to cart" button. It would not come with a pad.

Where will i need to supply electricity for the system to work, inside or outside or both?

The outdoor unit for this particular system requires a 15A double-pole breaker. The indoor unit will draw power from the outdoor unit via the communication cable included within the installation kit.

How many amps is does this need to run off? I'm asking so I can get the proper breaker. Thank you.

This particular system requires a 15A double-pole breaker.

How many square feet will this unit cool and heat

We recommend this unit to be used for rooms between 200 and 450 square feet.

What type of wire used to connect the mini split

For power to a 230V outdoor unit it would need 2 hots and a ground, THHN type.
For the gauge it would either be 14 or 12 AWG depending on your local electrical codes for 15 amps (the 2-pole breaker size needed for this unit).

What temperature does the heat pump work in? If it is 20 degrees outside, will the heat pump still work?

This particular system will heat and cool down to +5°F outside temperatures.
You can also consider our Inverter++ line, which HEATS down to -13°F.

How short can I cut the line set to ??

The minimum we recommend is 5 feet.

CAN THE INDOOR UNIT BE SEMI RECESSED

We do not recommend anything more than 1 inch as this can interfere with return air input.

Does this unit qualify for the 2024 tax credit ?

You would need the Energy-Star version which is WYS012GMFI22RL.

How cold on the AC. Can the interior of home be set This is for a bedroom we like it 60 to 62 degrees in summer

You can set it between 62 and 86F with a special 46F mode for freeze protection.

What’s the lowest outdoor temp can be for heating mode??

-13 Fahrenheit.

I ordered this mini split with 16 ft copper line. I realized that I need a 25 ft kit. Do I need to add extra refrigerant to the condenser or it will work with the factory load?

The factory pre-charge will cover 25 ft and shorter lineset runs.
