Tekonsha Primus IQ

Tekonsha Primus IQ is a budget brake controller with significant big brother main features.

The IQ is the preferred electric trailer brake controller for most caravans and camper trailers. The Primus IQ is not compatible with the Hydrastar unit.

Features an easy-to-set, snap-in-dash mounting clip and a removable electrical connector.

A proportional electric trailer or caravan brake control, the Primus® IQ is self-levelling. As a result, there is no levelling adjustment required during installation.

Note: Review this link for tips on troubleshooting electric brake drums.

A proportional electric brake controller that varies the amount of braking depending on how hard your foot is on the pedal.

Power Boost for Heavy-Duty Towing

Tekonsha’s Primus IQ brake controller offers a boost feature that gives you more initial braking power when you tow heavy loads.

You can switch boost levels so that the power output to your trailer brakes automatically starts at either 13% or 25% of the predetermined power setting.

So, if you boost the initial power so that your trailer brakes activate with 25% of the overall intensity at the start, the brakes will reach maximum braking faster.

This is particularly beneficial if you tow a heavy load because the intensity required to stop that load may be far greater than that needed to halt your vehicle.

Safety Features

The Primus IQ offers advanced safety features to prevent damage to various components of your towing setup. For example, this brake controller will be in power-saving mode when it is not used. In this setting, the power draw falls to minimize the drain on your vehicle’s battery.

When you stop at red lights or any time your truck and trailer standstill with the brakes applied for more than 5 seconds, the Primus IQ’s “hold” feature will activate.

When this happens, the power output to your Trailer’s brakes will be reduced to just 25% of the preset power setting so that the brakes will not overheat.

If ever there is a time that you need to brake your Trailer separately from your tow vehicle – when travelling down a steep incline, for example – the manual override is easily accessible.

Pushing this slide bar engages the brakes on your Trailer with full power. In addition, when you activate this override, the brake lights on your Trailer will illuminate.

In addition to all of those safety features listed above, the Primus IQ offers diagnostics such as:

  • Open ground
  • Overload
  • Output short
  • Faulty mounting
  • Power loss
  • No trailer connection

Automatic Leveling and Simple Installation

The self-levelling feature of the Primus IQ ensures that the brake controller continues to function even as you drive up steep hills or through the mountains.

Mount it in your cab at a vertical angle between 0 degrees (level) and 90 degrees, and the controller will level itself automatically.

Note: The Primus IQ must be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function correctly.
