Auto Flush adapter for Toto Washlet and THU767

This adapter allows you to mount a Toto THU767 auto-flush unit on a non-Toto toilet.  It should work on any toilet with a straight 28mm diameter overflow pipe (like the Fluidmaster 507A or 507AK).  I am working on a version for toilets with a flared overflow pipe (like the Fluidmaster K-507A or K540A).

You'll likely need to make some adjustments to the existing flush handle arm and/or other components to accomodate the THU767.  It's pretty simple really.

The THU767 auto flush unit works with the Toto SW3056AT40-01 S550e washlet (auto-flush ready), Toto SW3056#01 S550e (not listed as auto-flush ready but actually is) and possibly many others.

Printed in PLA+, 50% infill, 0.3mm layers.

To set up your S550e to use the THU767:

1) Remove seat-only top button assembly on remote and replace with flush + seat button assembly from the THU767 kit.
2) Press stop button on remote for 10 seconds.  All button start blinking.
3) Press flush button for 5 seconds. Listen for two long beeps and two light blinks on the seat over the power icon.
4) Simultaneously press front spray and oscillating button.  Listen for two long beeps and two light blinks on the seat over the power icon.
5) Press stop button to complete setup.
