The RAM AIR-PRO II is an intelligent and silent indoor climate controller designed to control two inline/exhaust fans thermostatically, monitoring and keeping the desired room temperature and air pressure. All you have to do is plug in your fans, set the required air temperature and fan speed/balance and the AIR-PRO will do the rest, maintaining a continuous room temperature in your room and giving you full control over negative pressure. The AIR-PRO II features a remote thermostat sensor and temperature setting, as well as twin fan speed control. This intelligent fan speed controller learns your optimum speed for the temperature/pressure that you desire. The unique software will automatically calculate the running speed for your fans and learn from this to modulate them (ramp down) to a single running speed that maintains the required temperature that you have set. A remote probe is fitted, accurate to within +/- 1 degree, that can be placed in the key temperature sensitive area. The RAM AIR-PRO II looks for a stable fan speed to maintain the desired temperature. This means that your fans will be running below the maximum operating speed. They will be operating at maximum efficiency in reference to power vs. performance, extending fan motor life, whilst only using the minimum electricity required.
