Description

About This Remote

At 5.1 kW (17,400 BTU), the Hitachi RAS-51CA3 wall-mounted split system handles a serious cooling load, and keeping it within reach means having a working remote control. Its part number is RAR-2P2, and it operates the unit over infrared with no programming, code entry, or pairing required. This replacement puts the everyday controls right where your thumb expects them, covering mode selection, fan speed, temperature adjustment, and timing functions across the Prima R410A fixed-speed platform.

The RAS-51CA3 runs on 220-240V / 50Hz single-phase power, and the CHA3 variant of the same platform also offers 5.5 kW (18,700 BTU) of heating capacity. This remote works across that Prima R410A line. It takes 2 x AAA batteries.

Why buy this remote

  • Covers temperature, mode, fan speed, and timer controls for the RAS-51CA3 split system.
  • Works with the full Prima R410A fixed-speed platform, including the heating-capable CHA3 variant.
  • Puts the everyday controls right where your thumb expects them so everyday adjustments stay exactly where you expect them.
  • Includes no programming steps, no code lookup, and no pairing procedure before use.

Frequently asked questions

Will this remote control work with my Hitachi RAS-51CA3 without any setup?

Yes. The Hitachi RAS-51CA3 remote control communicates and responds to the unit immediately once batteries are installed, with no code entry or pairing steps involved.

Does the RAR-2P2 remote also work with the CHA3 variant of the Prima R410A line?

Yes. This remote works across the Prima R410A platform, which includes the CHA3 heating-capable variant rated at 5.5 kW (18,700 BTU).

What refrigerant does the RAS-51CA3 use, and does that affect remote compatibility?

The RAS-51CA3 uses R410A refrigerant. Refrigerant type has no bearing on remote compatibility; the remote interfaces with the unit's control board, not its refrigerant circuit.

What batteries does the RAR-2P2 remote take?

It takes 2 x AAA batteries.

Is the RAS-51CA3 an inverter or fixed-speed unit, and does the remote reflect that?

The RAS-51CA3 is a fixed-speed, non-inverter design. This remote covers the control functions appropriate to that platform, including mode, fan speed, temperature, and timer settings, without inverter-specific options that would not apply.

Shipping and Delivery

๐Ÿ“ฆ Shipping Information

At USA Remotes, we’re committed to getting your replacement remote to you fast, free, and hassle-free โ€” the same way your remote shows up ready to use, with no pairing or programming. Below you’ll find everything you need to know about how we ship, how long it takes, and what to do if anything goes sideways.


๐Ÿšš How much does shipping cost?

Shipping is free on every order โ€” always. No minimum purchase, no handling fees, and no surprise charges at checkout. The price you see is the price you pay.


๐Ÿข Where do you ship from?

Every order ships from our U.S. fulfillment center. We’re a U.S.-based company, so your remote never sits in customs or crawls in from overseas โ€” it ships domestically and arrives quickly.


โฑ๏ธ When will my order ship?

We move fast. Orders placed before 2:00 PM Mountain Time (MT) on a business day ship the same day. Orders placed after the cutoff, on weekends, or on public holidays ship the next business day.

Business days are Monday through Friday, excluding national holidays.


๐Ÿš€ How long will it take to arrive?

Once your order leaves our warehouse, most deliveries arrive within 2โ€“4 business days. Paired with same-day processing, the majority of customers have their remote in hand within just a few days of ordering.

Delivery windows are estimates, not guarantees, and can run a little longer during weekends, holidays, peak seasons, or severe weather.


โšก Do you offer faster (expedited) shipping?

We don’t currently sell a separate paid expedited option, but many orders go out via USPS Priority Mail, which typically reaches most U.S. addresses in 2โ€“3 business days at no extra cost.

If you’re in a time-sensitive situation, email us at cs@usaremotes.com before you order and we’ll let you know what’s possible.


๐Ÿ“ฌ Which carriers do you use?

Because remotes are small and light, the vast majority of orders ship via USPS (United States Postal Service) โ€” usually USPS Ground Advantage or Priority Mail. For larger multi-remote orders we may use UPS or FedEx. The carrier is selected automatically to get your order to you as quickly and safely as possible.


๐ŸŒŽ Do you ship internationally?

Yes โ€” we ship internationally. International orders typically arrive within 8โ€“14 business days, depending on your destination and how long it spends in local customs. Carriers and shipping methods vary from country to country, so your order travels the most efficient route available.

Please note: international shipments may be subject to customs duties, taxes, or import fees charged by the destination country. These are set by your local customs authority and are the responsibility of the recipient.


๐Ÿ๏ธ Do you ship to Alaska, Hawaii, U.S. territories, and military addresses?

Yes. We ship to all 50 states, U.S. territories (including Puerto Rico, Guam, and the U.S. Virgin Islands), and APO/FPO/DPO military addresses. Because these rely on USPS, transit times may run a bit longer than the standard 2โ€“4 business days.


๐Ÿ“ฎ Do you deliver to PO Boxes?

Absolutely. Since most orders ship via USPS, PO Box delivery is no problem. On the rare occasion an order ships via UPS or FedEx, we may reach out for a physical street address.


๐Ÿ” How do I track my order?

As soon as your order ships, we’ll email you a tracking number. You can also check your status anytime on our Track Your Order page. If you don’t see the email within a day of ordering, check your spam folder or get in touch.


๐Ÿ“ง Why does my order say “Completed”?

When your order ships, you’ll get a confirmation email and your order status will change to “Completed.” That wording can be a little misleading โ€” “Completed” simply means your order has shipped and left our warehouse, not that it’s already been delivered. Just use the tracking number in your email to follow it the rest of the way to your door.


๐Ÿ“ญ My tracking number isn’t updating โ€” what should I do?

It’s normal for tracking to go quiet for a day or two, especially right after a label is created or over a weekend โ€” carriers don’t scan a package at every stop. If there’s no movement for more than 3โ€“4 business days, email us at cs@usaremotes.com and we’ll chase it down for you.


๐Ÿ“ฆ My tracking says “Delivered” but I don’t have it

If the carrier marked your package delivered but it’s not in your hands:

  1. Check around your home โ€” porch, mailbox, side door, garage, or wherever packages usually land.
  2. Ask household members or neighbors in case someone brought it in for you.
  3. Wait 24 hours โ€” packages are sometimes scanned as delivered slightly before they actually arrive.

If it still hasn’t turned up:

  • Contact your local USPS office โ€” they can pull GPS delivery confirmation showing exactly where the package was scanned.
  • Contact us at cs@usaremotes.com or (720) 204-8889. We’ll help open an investigation and retrieve the GPS scan data if needed.

Insurance: Our shipments include carrier insurance against loss or damage. We’ll guide you through the claim process with the carrier and stay on it until it’s resolved.


๐Ÿ’” My remote arrived damaged or doesn’t work

Every remote is tested and packed with care, but if yours shows up damaged or has a defect, you’re covered by our 1-year warranty and full compatibility guarantee. Just contact us at cs@usaremotes.com with your order number (and a quick photo if it’s physically damaged), and we’ll arrange a replacement or refund right away. Full details are in our Returns & Refunds policy.


๐Ÿ  What if I entered the wrong address?

If you spot a mistake in your shipping address, contact us immediately. If your order hasn’t shipped yet, we can fix it. If a package comes back to us as undeliverable (wrong or incomplete address), we’ll reach out to arrange a re-ship to the correct address.


๐Ÿ”€ Why did my order arrive in separate packages?

If you ordered more than one remote, your items may occasionally ship in separate packages or arrive on different days. Each shipment gets its own tracking number, so don’t worry if one lands before the other.


โ„๏ธ Holiday & weather delays

Carrier networks slow down during major holidays and severe weather. We still ship on our normal same-day schedule, but transit times may stretch during these periods โ€” and once a package is with the carrier, those delays are outside our control.


โœ… Our commitment to you

Your satisfaction is our priority. If anything goes wrong with your shipment, we’ll work directly with USPS or the relevant carrier to make it right and get your remote to you safely. Nobody should be stuck without a way to control their TV, sound bar, or AC.
