The major benefits of the Dragon Series of electronic thermostats are appearance, functionality, and affordability, the company says. The appearance is said to be designed to match the sleek, contemporary designs found in today’s offices, conference rooms, and classrooms. The series includes three models. The RAA provides simple on-off control, the RAB supplies on-off with fan speed adjustments, and the RCU is for use with a standard 0- to 10-vdc output.
