Advanced LT Controller v2 with On / Off & Variable Speed

MSRP: $0.00
MAP: $0.00


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 setpoints. The “on” setpoint for Mode 1 is 80˚F/27°C, and is most appropriate for equipment room or closet applications. The setpoint for Mode 2 is 90˚F/32°C, and is designed for cabinet, rack, and enclosure applications. Mode 3 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 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°F above the “on” setpoint. As the system cools down 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 alarm is set at a fixed 115˚F/41°C. Another advantage of the unit is that it can be mounted almost 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.
