Frequently asked questions.
How many rooms can this system heat and cool?
This is a 4-zone system: one CH-R48MES-230VO outdoor unit powers two 18,000 Btu/h one-way cassette zones, one 12,000 Btu/h one-way cassette zone, one 6,000 Btu/h one-way cassette zone, each with its own remote so every room sets its own temperature. The outdoor unit connects up to 6 indoor units total.
Will it keep my home warm in winter?
Yes — it's an inverter heat pump that keeps heating in outdoor temperatures as low as -13°F, still producing 36,000 Btu/h of heat at 5°F.
What's included in the box?
The CH-R48MES-230VO outdoor condenser (48,000 BTU), two× 18,000 Btu/h indoor unit (CH-RSH18MCT1W), one× 12,000 Btu/h indoor unit (CH-RSH06-12MCT1W), one× 6,000 Btu/h indoor unit (CH-RSH06-12MCT1W), and the built-in Wi-Fi Smart Kit. At checkout you add a line-set installation kit (copper line set, communication cable, drain line) for each zone.
What electrical service does it need?
208/230V single-phase power on a dedicated circuit for the outdoor unit — minimum circuit ampacity 34 A, maximum breaker/fuse 40 A. Have a licensed electrician confirm your panel.
How far can the indoor units be from the outdoor unit?
Up to 262.4 ft of line total across all zones, and up to 114.8 ft to any single indoor unit. It ships pre-charged for 150 ft.
What's the warranty?
