Ask a Question
  • Hello Can you tell me what is the Cooling EER Rate?

    It is 10.50.

  • I live in the Palm Springs, Calif area. I don't need HEAT. Does Pioneer offer a "cool only" option?

    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.

  • How much sf will this cover

    We recommend this for up to 450 SQ ft.

  • Does the Diamante Series have a refrigerant leak detection feature?

    Yes it does. In the event of a refrigerant leak, it will display error code Fy.

  • can you make the WYT012GLFI19RL a dual zone

    You cannot currently. You would need to shop from the multi-zone options.

  • what size wire

    The signal wire is included. The power wire needed is 14 AWG for the 15A breaker.

  • on the wyto12glf119rl 12,000 btu diamante series what is the lowest heat called for on the specs and should i get a zero rated unit?

    This particular system will function down to -13°F outside temperatures in heating mode.

  • How much R410 comes precharged. I have to have mine refilled. 16ft of line. Thanks!

    Factory pre-charge is 950g / 33.51ozs

  • What size breaker for the 12000 diamonte 19 seer?

    This unit would take a 10A double-pole breaker.

  • how long line can be use

    You can use up to 80 feet, but this series does have the ability to modify the length of the included 16 ft. lineset. You would need to get a separate line.

  • Can I order this with 50 ft line set

    You cannot modify the default 16 ft lines, if you are open to exending the line you would need to order a 33 ft lineset here and also a union piece here to make 49 ft.
