No reason why the ERV cannot kick on with a rise in humidity in the winter and no reason why it cannot be wired to come on everytime the furnace runs.
If it was ducted to draw air from humid sources then supply fresh air to the return duct work of the furnace it would pressurize the duct work and fresh air would spill out everywhere, in particular out of return vents when the furnace fan was off.
The ERV should give you year round fresh air without overdrying the house.
