Vent Learn Routine
The Learn Routine must be completed before Vent Learn Routine can be performed.
1. Roll both windows up all the way by holding both switches.
NOTE: The 535T needs to see BOTH switch inputs at the same time to enter programming.
2. Once the windows are all the way up; press and release the driver UP switch six times.
3. Press and hold the driver window DOWN switch until the window reaches the desired vent
position, and then release the switch. Use caution not to activate any OEM “AUTO” down
feature during this step!
4. The 535T records the time the output was active and sets it to memory as the vent time.
5. Two seconds after the vent time is set to memory the 535T rolls up the driver window and
then vents both windows using the learned vent time indicating that the learn routine was
successful.
Exit Vent Learn Routine
Either of the learn routines are exited if any of the following occurs:
• There is no activity on the inputs for more than 15 seconds.
• Incorrect switch input order.
• Any switch input is seen during the learn routine.
• Current threshold exceeds the units capabilities.
• Power loss.
