I put an LED and resistor on the monovalve coil to see if it was getting a signal. The ON OFF times were in seconds with an intermediate temp wheel setting. With the temp wheel at the extremes (detent positions: MIN or Max) , the valve is ON or OFF.
The mass of the monovalve plunger assemby does not lend itself to sub-second toggle rates.
