The valve is like your car thermostate  in reverse once the water temp drops below 170 the valve starts to close as the water gets to 150 it completly closes and loops the water back to the boiler to maintain 150 in the owb.  The line from the valve to your heat exchanger goes cold until the water temps starts to rise ( firing the furnace) In the mean time you get a cold house and/or a gas bill as the back up kicks in to maintain house temps.

The thermostatic valve is for protecting your furnace from condensation and corrosion.
My dealer NEGLECTED to install it, until I mentioned it.  THEN he installed it....  He mumbled something about condensation....I have no idea...  The furnace handbook states that it MUST BE INSTALLED!
or forget your 25 year warranty....
