Description
The Cooper & Hunter CH-RH18MASTWM-230VI is the Astoria wall mounted indoor unit sold on its own, for replacing an existing head or building a system with a compatible Cooper & Hunter outdoor unit. Astoria is Cooper & Hunter's core wall-mounted line on R-454B. The electrical box and control board sit at the front of the unit behind a cover with a kickstand, the blower wheel comes out without pulling the chassis, and the magnetic filter lifts out from the top. A wireless remote and the Smart Kit (Wi-Fi, C&H app) are included; a wired wall controller is available separately. This Astoria version does not have the factory refrigerant detection sensor (see Astoria Pro for the RDS model).
