Overview
The Cooper&Hunter CH-RS06-12MDT-MS is a dynamic 6K-12K Btu multiple-capacity slim duct designed for single or multi-zone applications, using the new R454B refrigerant. The ENC1 dip switch allows easy capacity changes, and the slim profile installs cleanly into tight ceiling or wall spaces.
With medium static pressure capability, this unit delivers consistent performance up to 21.4 SEER2. High-quality TU1 copper tubes provide durability and superior heat transfer, while a built-in refrigerant sensor helps ensure precise climate control.
Features
- Multiple capacity options (6K-12K Btu) via ENC1 dip switch
- Built-in Smart Kit with downloadable C&H app for remote control
- Included wall thermostat and remote control
- Compatible with regular or hyper heat pump outdoor units
- R454B refrigerant with TU1 copper tubing
- Built-in refrigerant sensor
- Slim design for installation in ceilings or walls
What's Included
- CH-RS06-12MDT-MS slim duct indoor unit
