Early Whirlpool water temp
My early TOL whirlpool, has 3 thermostats mounted on the side of the outer washbowl. One for Hot, one for Medium, and One for warm.
The inlet valve is just a standard 2 solenoid jobby.
It the logic in the Timer/Thermostats that controls how and when the valves open rather than in the inlet valve body.
In testing I've gotten around it by having 3 taps installed.
One is hot with a hose adapter, one is cold with a hose adapter, and then there is a cold tap to the hot water, so I can effectively run cold water through both hoses.
