A stationary "standard" mark and multiple variable marks on a rotor can be matched to one stationary "standard" mark on an adjacent stator throughout valve movement. All marks can be color and touch coded, and each variable mark can be anchored by a slot. The connection between the rotor and stator sections allow rotation about a common axis of the rotor relative to the stator. The connected stator is anchored to a protruding pipe or outer sleeve of a valve stem. The rotor can be attached to a valve stem and can double as a faucet handle. When a temperature and pressure is obtained, it can be set in memory by sliding a variable mark to match the stationary "standard" mark on the stator. The two "standard" marks can be matched when a common bathing temperature and pressure is desired. The color and touch coded marks enable people with good sight, poor sight, and blind people to use the device.
