TOTO's 2023 spare-parts price list also explicitly identifies TCM1150-1RS as “Cụm van điện từ (Valve Unit)” (solenoid valve assembly).
What does it do?
The TCM1150-1RS controls the supply of water to the WASHLET's internal functions. The electronic controller energizes the solenoid valve when water is required and closes it when water flow is stopped.
It is therefore involved in functions such as:
- 🚿 Rear/front washing water supply
- 💧 Controlling water entering the WASHLET's internal water circuit
- 🔄 Opening/closing water flow according to the electronic control system
- Working together with the nozzle, heat exchanger and controller assemblies
Trade records also specifically describe TCM1150-1RS as a solenoid valve with a plastic body used to automatically open and close the wash-faucet water supply of a toilet seat cover.
Important: TCM1150-1RS is a valve assembly, not the nozzle itself. The nozzle is separately listed as TCM1157-1SR.
If you give me the TOTO WASHLET model number (e.g. TCF4731A, TCF4732A, TCF9786WA), I can check whether TCM1150-1RS is the correct valve for that model and provide its connection/function diagram.
