Temp Controllers

Fan Controllers Provide Automated Control of the Cooling and Ventilation Products

One of the most common differences with controllers is if they are On/Off only, or On/Off/Variable speed.  Beyond this, some units have fixed set point and other's have multiple selectable set points (fixed but several to choose from) and then there are fully programmable units.

All of the controllers simply plug inline between the power supply and fan unit except the EC controller.

Quick Reference To Temperature Controllers 
  • Basic Temp Controller - On/Off 80 (TC-BSC-80) - Basic on/off control based on a fixed setpoint of 80 degrees.  This setpoint is appropriate for closet applications and would commonly be used with products such as the HiFlo Systems.
  • Basic Temp Controller - On/Off 88 (TC-BSC-88) - Basic on/off control based on a fixed set point of 88 degrees.  This setpoint is appropriate for component or cabinet applications - when installing coolers and the controller in close proximity to equipment.
  • Basic Temp Controller - On/Off 100 or 110 (TC-BSC-100/110) - Basic on/off control based on fixed set points of 100 & 110 degrees.  These set points are appropriate for cabinet, rack, and enclosure applications where there are either extreme circumstances where the ambient temperatures can rise quickly to temperatures of 100 to 110 degrees or more, or where placement of the controller is in close proximity to heat generating components with average operating temperatures of 100 to 110 degrees Fahrenheit or more,
  • Advanced LT Controller (TC-ALT) -  Features basic on/off control as well as advanced variable speed control.  The unit features three selectable modes with different on/off set points. The setpoints are at 80°F/27°C, 90°F/32°C, and 100°F/38°C
  • Advanced LT Pro Controller (TC-ALT-PRO) -  Features basic on/off control as well as advanced variable speed control.  The unit features five selectable modes with different on/off set points. The setpoints are at 70°F/21°C, 80°F/27°C, 90°F/32°C, 100°F/38°C and 110°F/43°C 
  • Advanced LT 3 Fan Controller (TC-ALT-3FN) -  For controlling 3 sets of fans independently.
  • Advanced System Controllers (TC-ASC & TC-ASC-2) - The  most advanced controllers available for controlling ALL DC fans.  Both are fully programmable, feature alarm with contact closures, low voltage trigger and much, much more.
  • Advanced Ventilation Controller (TC-AVC) - Specifically designed for closet venting systems with programmable setpoints and alarm feature.  Directly control high voltage fans or control low voltage fans by hard-wiring the controller to an outlet.

Additional Information on Power Supplies

There are several options when power the units in relation the running of fans. The first option is leave the fans running full time. The second option is to switch the fans from the equipment (from a switched outlet on a receiver, amp, or other components if equipped). Those two options do not require purchasing any additional equipment. The next options involve adding a controller into the cooling system. The Basic Controller option simply turn the fans on and off based on temperature. The next option is to use the Advanced LT Controller which provides on and off control as well as variable speed control both based on temperature.  Then there are the ASC Controllers, single and dual rack mountable versions, which these offer full programmability and other features for professional applications.  There is also the AVC controller which in On/Off but is also a high voltage controller as well.  Typically it would be wired to an outlet and the controller would 'trigger' the outlet.  The EC controller is only for use with the EC Inline Duct Fans.

Best Practices. There are several principles when considering the different options for powering the units. The first is to consider when components require additional airflow. Some components such as cable and satellite receivers generate heat in both the on and off modes. This is simply because the receivers are continually downloading menus and are simply on all of the time. Then other components generate heat only while on and others only when being driven played loudly

For always on components, cooling products can and probably should be run full time with those units. Since the rest of the system is off, this heat most likely will not cause any damage but the fans could be run full time just to keep the heat in check. Then switching products from the component they are on is a great control option that comes with no additional costs. Now in days, more and more receivers do not have switched outlets but if you do have a switched outlet, strongly consider switching the cooling products from that outlet. A tip is to use a lamp cord to plug into the amplifier or receiver and then plug the power supplies into the other end of the lamp cord. This just keeps the bulky power supply off the back of the receiver.

Another option for the always on components and most other situations is to use the Basic Controllers. When the heat rises to the set point (80 or 88 degrees F), the fans turn on. Then when the temperature goes below those points, the fans turn off. This simply ensure that the fans are only running when necessary. Our fans are very high quality and are rated for at least 50,000 hours of operation but it is not a bad idea to only run them when necessary. For the different set points, use the 80 degree unit when measuring the temperature in a closet and the 88 degree unit when measuring the temperature close to components. When then measuring around the components, you can further manipulate the on/off point simply by moving the sensor closer or further from the components either directly on a component or on the back of the cabinet or shelving (further from the components).

Then the most extreme option is to use the Advanced Controller which again, turns fans both on and off but also varies the speed of the fans as the temperature changes. As the heat increases, the fans spin faster. The benefit to this unit is that it does provide a greater level of protection of components. It allows the fans to cool at a minimum speed for the most quiet operation when heat is at lower levels but then as things heat up, the controller speeds up the fans automatically which provides maximum protection.

Product Usage Tips - While there are specifications that indicate a setpoint and degrees of variance, several factors and challenges exist when measuring ambient air temperature in an uncontrolled environment.  Adding cooling and ventilation products add in a degree of control, but unless working with a sealed enclosure, it is still difficult to regulate and control the amount of pathways of airflow.  For this reason, the temperature controllers may not seemingly operate in the range specified.  If encountering an issue, the best course of action is to simply consider the placement of the controller.  Very generally speaking, if the controller activates too early or does not turn off, back it away from components and put in a known airflow pathway.  In other words, do not leave it resting on a component.  If it is delayed in activating fans, then do the opposite, move it closer to the component and area where heat will accumulate.

Common Issues & Misconceptions Related to Temperature Control. There are a few misconceptions when it comes to control options so take it from the pros who are most concerned that your systems run effectively and do not have a desire to sell you features or options that you do not need.

1) You Must Have Temperature Control. As you have already read, there are control options that do not require added equipment or expense. Because these options exist and are completely valid, why have built-in control? As with most things, it is best to keep things simple and only add features and options if required. With our controllers, simply plug them inline between the fan units and power supplies for advanced control.

2) More Control is Better. It may be enticing to simply order the Advanced Controller and have the highest level of control and protection but such protection is not always necessary. Many components are very easily cooled and just by switching them from the equipment will solve heat problems in most cases. In other situations, simply turning the fans on and off using a Basic Controller is effective both in cost and functionality. All of our cooling and venting products have been tested at quiet settings so by setting the units to be quiet and then adding in a controller, you should have an effective solution.
