TOTO THP3391 – Frequently Asked Questions
1) What is the TOTO THP3391 part used for?
THP3391 is the IoT ASD control board, a replacement electronic board for a TOTO automatic soap dispenser. It is the control electronics only, not a complete dispenser, so you order it when the dispenser body and reservoir are fine but the unit has stopped sensing or dosing.
2) Does the TOTO THP3391 control board come with the soap dispenser housing or pump?
No. THP3391 is supplied as the control board alone. The dispenser body, sensor housing, pump assembly and soap reservoir are separate items, so if the failure is mechanical rather than electronic this board will not fix it.
3) I manage several restrooms with TOTO touchless soap dispensers - is THP3391 the right repair part for any of them?
Order THP3391 only for TOTO IoT-enabled automatic soap dispensers. It is the control board for that IoT ASD platform, so match it against the dispenser model you actually have before standardizing a spare on the shelf. A non-IoT TOTO auto dispenser uses different control electronics.
4) What part number should a maintenance tech quote for a TOTO IoT soap dispenser control board?
The TOTO manufacturer part number is THP3391. That is the number to put on a purchase order or give to a facilities tech for the IoT automatic soap dispenser control board.
5) Is the TOTO THP3391 available in different finishes or versions?
There is one version, THP3391. Finish is not a factor on a control board since it mounts inside the dispenser and is never seen once the unit is closed up.
