Power Source / Network

Power Source

The Prolon controller is powered by the HVAC equipment's 24 VAC supply by connecting the common or ''C'' wire to the
"COM" terminal and the live or ''R'' wire to the "24 VAC" terminal. The common for all inputs and outputs is the same as
the power source's common. All output power sources also originate from the controller's power source.

Network Communication

The Prolon C1050 Heatpump controller is primarily designed to work with Prolon zone controllers. When they are net-
worked, the Heatpump and zones all communicate in real-time using Modbus RTU protocol over RS485. The network
connections are made using the NET terminal block located on the Prolon controller.
