TOTO THP3105 – Frequently Asked Questions
1) My TOTO sensor faucet won't turn on after new batteries. Will replacing the controller fix it?
If the sensor faucet has fresh batteries, clean contacts and a clear sensor lens and still will not actuate, the controller is the next part in line, and THP3105 is the TOTO controller and harness assembly for the electronic faucet. Confirm THP3105 is the controller TOTO lists for your specific faucet model before swapping it in.
2) What is the TOTO THP3105 part?
THP3105 is a TOTO controller assembly for an electronic (EcoPower/sensor-type) faucet, supplied with the battery harness. It is the control module side of the faucet, not the spout or sensor body, so it is what you order when the faucet stops actuating and the controller is the suspect component.
3) Is the TOTO THP3105 a whole faucet or just a replacement part?
It is a replacement service part only. The THP3105 covers the faucet controller with its battery harness, so the existing TOTO faucet body, spout and sensor stay in place on the deck.
4) How do I make sure I order the right TOTO faucet controller?
Order by the TOTO part number stamped in your faucet's service literature. THP3105 is a single, non-optional part number with no size, finish or voltage choices to specify, so if TOTO lists THP3105 for your faucet model, that is the complete order.
5) Does the THP3105 TOTO controller come with the wiring harness, or do I buy that separately?
The battery harness is part of the THP3105 assembly, so you are not sourcing the harness as a second line item. Batteries themselves are not part of the controller assembly.
