Is oonstant speed.
One CR pump connected to an external &fFC4
always starts first. If the pressure cannot be
maintained by the pump, flee second CR pump
connected to an external VFD will t?e cut in. If the
pressure cannot be maintained by the two
pumps, the constant speed pump will be cut in.
Pump changeover is automatic and depends on
load, time and fault.
