(****) The water content of the system must be between the minimum and maximum values for the units with hydronic kit and greater than the minimum
value for units without hydronic kit. The minimum value is necessary to provide optimal comfort.
For units without hydronic kit, add a suitable expansion vessel to the water content of the system.
