Frequently Asked Questions
We put this section in here to help you quickly get to the answer you need. If you need to speak to some one please call us at the numbers listed on the top right of each page.
Q: Is the TruControl™ simple to install?
A: Yes. It connects to your 4-wire harness and mounts to the dash
using two self-tapping screws. Total installation time is under 15
minutes.
Q: Can the unit be damaged if I connect
it wrong?
A: No. TruControl™ has reverse polarity protection. It simply will
not power up if connected wrong. Just disconnect the wires and try
again.
Q: Will the TruControl™
work with electric over hydraulic brake systems?
A: The TruControl™ can be used with any kind of braking system
without modifications. It automatically detects which type of system
you have and adjusts for it.
Q: What is the onboard computer software
for?
A: TruControl’s™ patented software establishes a braking “profile.”
This profile was developed by monitoring the hydraulic pressure in
the tow vehicle’s brake lines. We found that this profile is always
the same, but at different power levels. That’s where the automatic
gain comes in. It simply “shifts” the braking profile according to
the amount of power required.
Q: What kind of guarantee and warranty
comes with the TruControl™?
A: Hensley Mfg. will replace the TruControl™ for the first 2 years of the
original owner for any malfunction. There is also 60 day money back
guarantee for any reason.
Q: Can TruControl™ be adjusted to haul
multiple load configurations, like with horse trailers or toy
haulers?
A: Yes. The UP and DOWN arrows on the front of the unit change the
CFG with just the push of a button. For example, if you’re hauling
an empty horse trailer, your CFG might be 8. When you haul one
horse, you’ll change the CFG to 9. Two horses-10. And so on. For
small load adjustments (under 1,000 lbs.), no adjustment is
necessary.
Q: Will TruControl™ account for trailer
brake fade?
A: Yes. Brake fade is caused by heating of the trailer brake
magnets. Since this changes the amperage pull of the magnets,
TruControl™ will adjust the gain accordingly.
Q: Will the TruControl™ alert me if my
trailer becomes disconnected?
A: Yes. A “Trailer Disconnected” warning displays if the trailer
becomes disconnected.
Q: Will the TruControl™ work in reverse?
A: Yes. TruControl™ functions in reverse.
Q: I’ve had other brake controllers burn
out while traveling through mountains. Will TruControl™ perform
better?
A: Lower priced brake controllers do not have the capacity to handle
a heavy amperage load for extended periods, like when you’re
constantly braking on steep grades. TruControl™ has a robust design
that allows for 48 Amps of burst and 32 Amps of continuous load.
Since most trailers will draw far less than that under the most
extreme conditions, TruControl™ will never overheat or burn out.
Q: Will TruControl™ adjust power output
for uphill and downhill grades?
A: Yes. On downhill grades, TruControl™ will send more power to the
brakes. On uphill grades, it will send much less, giving you a
smooth and powerful stop each time.
Q: Why is it necessary to level, or
calibrate the TruControl™? Other brake controllers don’t require
that.
A: To achieve the kind of performance that the TruControl™ gives, it
is necessary level the solid-state gyro. Brake controllers that work
off an accelerometer but don’t require leveling cannot provide
smooth stops in every situation (uphill and downhill grades for
example). Calibration takes seconds and places the TruControl™ at a
naturally comfortable position. Once the unit is calibrated at set
up, you never need to adjust it again.
Q: How many axles will TruControl™ work
with?
A: TruControl™ Gold will provide full power for up to 4 axles.
