Unit Plumbing
There are several water valve options available to regulate flow to the heat pumps.
A. WWKVS – is designed for use with variable speed units, and dual capacity units with AXB controls. When using this kit you will
need to use the AID tool to adjust minimum and maximum flow rates. The factory default is minimum = 50% and maximum =
100% flow rate for variable speed units, and minimum = 75% and maximum = 100% for dual capacity units. Refer to the units
Installation manual under unit Start Up for more information on setting up through the AID tool. Always ensure that there is
adequate flow for the heat pump. Refer to the units Specification Manual for minimum and maximum flow rates. NOTE: the
10DC must be attached to screw position 1 on the VS labeled section of the AXB. See figure 10 for wiring schematic.

B. WWK3T – is designed for dual capacity units without the AXB controls. This kit uses solenoid valve, slow closing valve, and ball
valves to regulate flow for both high and low speed operation. Always ensure that there is adequate flow for the heat pump. Refer to
units Specification Manual for minimum and maximum flow rates. See figure 11 and 12 for wiring schematic.
