System Information
With the push of a button, the Ground Control® TT Leveling System levels and stabilizes your travel trailer quickly
and accurately, enhancing your overall camping experience. It can take up to an hour to get a travel trailer level
with manual jacks, chocks and wedges. The Ground Control® TT Leveling System saves you time by leveling and
stabilizing the travel trailer in a matter of minutes, and prevents annoying rocking and swaying at the campsite.
Features:
1. Saves time setting up camp
2. Fast, accurate automatic electric leveling
3. Auto re-hitch memory function
4. Level travel trailers function more efficiently than non-level ones
The controllers for this system are automatic leveling controls and interface to the Ground Control TT Leveling
system to level the trailer. The system utilizes one main control board and a separate waterproof remote level sensor
to measure and manage level point, and can be operated from several user interface devices, including:
• Auto Leveling Control Touch Panel - Mounted outside the trailer within view of the hitch.
• MyRV® OneControl™ Touch Panel (OCTP) - Mounted on a wall inside the living space of the trailer or in a
trailer compartment.
• MyRV® OneControl™ Leveling App - The app is available on iTunes® for iPhone® and iPad® and also on Google
Play™ for Android™ users. iTunes®, iPhone® and iPad® are registered trademarks of Apple Inc. Google Play™
and Android™ are trademarks of Google Inc.
• Linc® Remote Control - Optional.
NOTE: The Ground Control ® TT Leveling is specific to travel trailer applications only.
There are 2 different options for the controller depending on which jacks are installed:
A. HD Blue Controller - Part #433632. Installed 2 C-jacks, 2 Hall Effect 5K jacks, uses Auto Leveling Control
Touch Panel and OneControl Touch Panel.
B. SE Green Controller - Part #433633. Installed 4 C-jacks, uses Auto Leveling Control Touch Panel and
OneControl Touch Panel.
Safety Information
Failure to act in accordance with the following may result in death or serious personal injury. The use of the
Ground Control® TT Leveling system to support the trailer for any reason other than which it is intended is
prohibited by Lippert’s limited warranty. The Lippert leveling system is designed as a “leveling” system only
and should not be used to provide service for any reason under the trailer such as changing tires or servicing
the leveling system. Any attempts to change tires or perform other service while trailer is supported by the
Ground Control TT Leveling system could result in damage to the trailer and/or cause death or serious injury.
Prior to Operation
The leveling system should only be operated under the following conditions:
1. The trailer is parked on a reasonably level surface.
2. Be sure all persons, pets, and property are clear of the trailer while the leveling system is in operation.
3. Make sure battery(ies) are fully charged and test at 12+V DC under load.
People and pets should be clear of the trailer while the leveling system is operated. Never lift the trailer
completely off the ground. Lifting the trailer so the wheels are not touching the ground will create an
unstable and unsafe condition.

Special Jack Error Codes on OneControl Touch Panel or OneControl App
To clear the error codes listed below:
1. Correct or otherwise repair the issue (see the table below).
NOTE: In order to clear the special jack error code the jacks need to be “homed.” In order to “home” jacks,
each jack must be able to retract a minimum of 6”.
NOTE: The Power Tongue Jack does not need to be “homed.” The Power Tongue Jack cannot be operated
from the OneControl Touch Panel or OneControl App while clearing the special jack error codes.
The Power Tongue Jack can be operated using the “RET/EXT” switch on the tongue jack during this
procedure.
2. Extend all jacks to reach the 6” of minimum retract needed.
A. Press “EXTEND” and “FRONT” to extend the front jacks (if required).Refer to “Operation -
OneControl Touch Panel” and “Operation - OneControl App.”
B. Press “EXTEND” and “REAR” to extend the rear jacks (if required). Refer to “Operation - OneControl
Touch Panel” and “Operation - OneControl App.”
3. Press “ENTER” to AUTO RETRACT. The jacks will retract until they reach the hard current limit. The
Power Tongue Jack will perform an automatic grounding during the AUTO RETRACT sequence.
4. The jacks are now “homed” and the special jack error code will be cleared.

Moving parts can pinch, crush or cut. Keep clear and use caution.
Manual Override
NOTE: For ease of manual override it is recommended to unplug the power harness to the motor prior to
performing the manual override procedure.
NOTE: Use of a 12-18 volt cordless screw gun or pneumatic screw gun is acceptable to manually override
the jacks. Do not use an impact screw gun to perform any of the override procedures, as this may
damage the motor. If manual override is necessary there are two options for each style of jack.
NOTE: If the travel trailer is equipped with 4 C-Jacks the override procedure is the same for the front and rear.
C-Jack Motor Override:
Tools needed: 3/8” drive ratchet and extension (no socket)
1. Find the port on the jack gearbox (Fig. 19A).
2. Remove the rubber plug (Fig. 20A).
3. Insert the 3/8” drive into the port.
4. Turn the override until the jack extends or retracts to desired position.
C- Jack Manual Override Nut:
Tools needed: 3/4" socket wrench
1. Locate the manual override nut (Fig. 19B).
2. Place 3/4" socket wrench over the manual override nut (Fig. 21A) and turn the override nut until the
jack extends or retracts to desired position.
