ABSTRACT:
The described invention embodies a plumbing fixture device for the determination and display of exacting control adjustments necessary to achieve a predetermined fluid temperature blend. The device of the invention employs an apparatus constructed of a set of manually operated fluid control valves with an enclosing valve body, and a temperature mixing indicator consisting of an electronic signal indicating means to translate and communicate sensed fluid discharge temperature into display indications depicting the need for a specific corrective control action by the operator. The electronic signal indicating means is an integral part of the fixture which for reasons of reliability is electrically activated by a fluid flow switch mechanically linked to the fluid control valve handles and provides a positive sequence of display indications that culminate in a quiescent state when the desired temperature range has been obtained.
