Pioneer® 12,000 BTU 22 SEER 230V Mini-Split Inverter++ Aire acondicionado Sistema de bomba de calor Conjunto completo

are these unit set up to run power to the outside condenser and the inside evaporator powered by communication wire or does the inside need its own power source?

Only the outside unit needs a dedicated power supply. The inside unit is powered by the outside unit via the included signal cable alone.

Does the 21.5 SEER 12,000 BTU 230V unit heat down to -13?

Yes it does.

what is the size of the inside unit?

• Net Dimensions (WDH): 31.5 x 7.3 x 11.6 Inches

Does the wall unit need to be on a outside wall

That would be ideal, but if an outside wall is not available, you can put it on an inside wall and tap into a nearby sewage line from kitchen or bathrooms, or incorporate a condensate pump to route draige upwards and elsewhere.

With the 230V 19 seer 12,000 btu, what gauge wire do you run from Ac unit to the double 15 amp shut off?

It would be 14 AWG, or better. The wire is 2 hots and a ground with no neutral.

Do I need a 20 amp breaker or a 15 amp breaker for this unit? Is it a single pole or double pole?

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

Would it be possible to mount the unit on the ceiling instead of on the wall?

Not possible due to drainage. You would need to consider our ceiling mount type units.

Does the line set come flared or will I need to flare the lines myself?

The lines are pre-flared and ready to connect.

Does require a 220 circuit or 110? ( I am novice with electricity and am trying to determine what power I need run to the building we are installing the mini-split. Thank you.

This particular unit would require 230V supply. We have a 115V option as well if that is desired.

Is it programmable?

By default no, but you can add this USB dongle to make it programmable.

When figuring how long is needed for the cooling lines where should the measurements be taken from

Generally the installation kit would just be the distance between where you expect to mount the inside and outside units, as that is what connects them together.

How large of a space do this unit cover?

For typical applications, we recommend this for 200 - 500 square feet.

at what temperature does the 22 SEER stop heating? you show the 19 SEER stopping at 5 deg F.

All 22 SEER units heat down to -13°F.

Can you add an extra wall mount to the base unit in the future?

For that you would need to explore our multi-zone options.

What type compressor?

This uses a rotary-type compressor.

Does this unit also need a 15A double-pole breaker using 12 or 14 gauge wire like the 19 SEER 12,000 BTU unit?

This particular unit takes a 20A double pole breaker, but a 15A is also permissible. If using 20A, it requires 12 AWG to be up to code. 15A can be used with 14 AWG.

Other than SEER Rating and price, is there any difference between the two 12,000 BTU 230 volt units?

The 22 SEER Inverter++ unit also has an auxiliary heat strip on outdoor unit which allows unit to function down to -13 degrees Fahrenheit for the colder states. It is also Energy-Star rated which could help with rebates. The 19 SEER Inverter+ stops heating at 5°F and is not Energy-Star rated.

If I need backup generator to run this unit efficiently , how many watts are we looking at?

This particular 230V unit has the following electrical demands: 
Cooling: 923W average  (325W min ~ 1283W max)
Heating: 1085W average (495W ~ 1447W max)

Is a nitrogen pressure test required or recommended for the Pioneer EStar mini-split system?

It is not required per se, but is highly recommended for a proper installation as a safeguard. You can pressurize the system to 500 PSI using nitrogen and check for any leakage.

Can you hang the indoor unit verticale on the wall? Interested in the 12,000 btu, 230 volt.

No unfortunately you cannot. It must be horizontal as depicted.

Is there a unit available WITHOUT heat? Only need the cooling side.

All of our systems are heat pumps meaning heating and cooling. We do not carry AC only units, but you can disable the heat function if not needed.
