Advanced LT PRO Controller

Automated On/Off & Variable Speed Control The TC-ALT-PRO has added feature, more modes than the standard version and is the best choice for professional installations.  This unit provides automated on off and variable speed control based on temperature.  It also features an alarm and five (5) selectable modes with different on/off setpoints.  The “On” setpoint for Mode 1 is 70°F/21°C, and is appropriate for colder applications like server rooms. Mode 2 setpoint is 80°F/27°C, and is most appropriate for closet venting applications. The setpoint for Mode 3 is 90°F/32°C, and is designed for cabinet, rack, and enclosure applications. Mode 4 is 100°F/38°C, and is also designed for cabinet, rack and enclosure applications but offers a higher setpoint for applications where the controller’s 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 as is Mode 5 with a setpoint at 110°F/43°C. 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°F above the “On” setpoint. As the system cools the fan/s will slow down in a linear progression and ultimately turn off when the temperature drops ~3°F/2°C below the “On” setpoint. The PRO version also features 3 Alarm modes, Alarm Mode 1 is to deactivate the alarm (Alarm Off), Mode 4 is alarm on at 115°F/41°C and Alarm Mode 3 is 125°F/52°C.
