6.8.3 Hydronic heat pump circulator
The hydronic heat pump circulator must be field-installed and wired. Use a pump control module,
or bring low-voltage wires to the outside unit J6 terminals "CIRC PUMP" to switch a 24V relay
circuit indoors, as shown here:

IBC recommends the application of the either the IBC Sky 35 module for load circulator control
or, alternatively, using a pressure-activated load circulator for which control is unnecessary.
