The Pentair IntelliComm 4 communication center provides automatic control of the IntelliFlo and IntelliFlo 4 pump. The IntelliComm provides four pairs of input terminal connections. These inputs connectors are actuated by either 15 VAC to 240 VAC or 15 VDC to 100 VDC from the source device such as an automation controller, heater, or heat pump. Using the device's inputs, the four IntelliFlo external control programs can be enabled. If more than one input is active, the highest program number will be communicated to the IntelliFlo pump. The IntelliComm will always be configured to communicate to pump address number 1.
