Ram Air-Pro II Controller Temperature / Minimum Speed

The RAM AIR-PRO II is a smart, silent indoor climate controller designed to thermostatically control exhaust and intake fans, controlling and maintaining air pressure and desired room temperature. Simply plug in the fans and set the air temperature and fan speed/balance you want, and the AIR-PRO II controller will do the rest, maintaining a constant room temperature and giving you full control over negative pressure. The RAM AIR-PRO II features a remote sensor for thermostat and temperature setting, as well as twin fan speed control. Advantages: - Learns the optimal fan speed for the desired temperature/pressure. The controller automatically calculates the fans' operating speed and, from this data, modulates (reduces) them to a single operating speed that maintains the precise temperature to which it has been set. - Limits fan noise by preventing excessive airflow. - Extends fan life and saves energy. - Controls most fan sizes.
