The TC-ALTv2 provides automated on off and variable speed control based on temperature. It also features an alarm and three selectable modes with different on/off set points. The "On" set point for Mode 1 is 80°F/27 degree C and is most appropriate for equipment room or closet applications. The set point for Mode 2 is 90°F/32 degree C and is designed for cabinet rack and enclosure applications. Mode 3 is 100°F/38 degree C and is also designed for cabinet rack and enclosure applications but offers a higher set point for applications where the controllers sensor must be in close proximity to components or a higher temperature is simply desired. This mode is also ideal for two stage cooling applications when two controllers are used with one controller set on Mode 2 and another set on Mode 3. For each Mode the fan/s will turn on at 50% speed and will increase in speed in a linear progression until full speed is reached at ~10 degree F above the "On" set point. As the system cools down the fan/s will slow down in a linear progression and ultimately turn off when the temperature drops ~3 degree F/2 degree C below the "On" set point. The alarm is set at a fixed 115°F/41 degree C. Another advantage of the unit is that it can be mounted most anywhere since it utilizes a remote sensor. In even more extreme applications the sensor can be extended to control remotely mounted fans in projector enclosures ventilation applications etc.
