MSZ-HM12NA-U1 Mitsubishi Mini-Split Air Conditioner Remote Control

About the Mitsubishi MSZ-HM12NA-U1 Remote

We built this remote for owners of the Mitsubishi MSZ-HM12NA-U1. It sends the infrared commands your MSZ-HM 12,000 BTU wall unit listens for, so you can change mode, nudge the temperature, pick a fan speed or set the timer from your chair.

Our team matched this remote to the MSZ-HM12NA-U1. Confirm that number on the label of your indoor unit, then put in two AAA batteries. No codes, no pairing, no app.

• Matched to the 12,000 BTU MSZ-HM12NA-U1
• Full everyday control of the indoor unit
• Mode, temperature, fan speed and vane swing
• Clean white case

Kids, pets and missing remotes

Small remotes slip under couch cushions and into toy bins. A fixed home spot helps, and in a busy household a second remote is cheap insurance. If a pet has chewed the old one, recycle it: a damaged board can send stray signals.

Where to keep the remote

Pick one home for the remote, like a small adhesive holder by the door or a tray on the nightstand. Keep it out of direct sun and away from the sink. The box contains just the remote, so if you want a wall holder, any basic remote caddy from a hardware store works well.

Before you order

• Match your indoor unit's label to MSZ-HM12NA-U1 before ordering.
• Bigger 18k or 24k BTU unit? Choose our E22P88426 instead.
• Model-specific, not universal: it won't run other AC brands.

Setup & Pairing

Setup takes about a minute.

1. Load two AAA batteries (not included).
2. Aim at the indoor unit from where you normally sit and press the power button.
3. If nothing happens, check the batteries and the breaker, then try again from a little closer.
4. Try the fan speed and vane swing buttons to confirm everything responds.
