Product Description 

Model:DIYM248HPW02D00    

 

The MRCOOL DIYM248HPW02D00 is a high-performance DIY dual-zone configuration built using MRCOOL’s most powerful condenser — the 48K 6-Zone Double-Stack system. It combines a 9,000 BTU wall unit for a smaller room and a 36,000 BTU wall unit for a large, open space.

This setup delivers premium comfort for:

✔ Small quiet spaces — 9K unit

• Bedrooms
• Home offices
• Kids’ rooms
• Small apartments

✔ Large, high-demand areas — 36K unit

• Big living rooms
• Open concept homes
• Workshops
• Finished basements
• Large retail or commercial spaces

And even after powering both zones, you still have four unused ports on the 48K condenser for future expansion.
