Carrier's motorized water valves are normally closed, 2-position water valves. The valve opens to allow 100% of the fluid to flow through the coaxial heat exchanger, only when there is a call for compressor operation.
The valve is wired to be energized when the compressor contact is energized. The ability able to close off fluid flow to the unit when there is no call for cooling or heating reduces system operating costs. These valves are best used with variable speed pumping, which reduces the speed of the primary loop pumps.
