Power Source & Network
Power Source
Network Communication
The M2000 controller is powered by the HVAC equipment’s 24 VAC power supply (class 2) by connecting
the common (’’C’’ wire) to the "COM" terminal block and the live (‘’R’’ wire) to the "24 VAC" terminal block
(see Figure 19). The common for all inputs and outputs is the same as the power source’s common. All
output power sources also originate from the HVAC equipment’s power source.
The ProLon M2000 Rooftop controller is designed to work with the ProLon zone controllers. When they
are networked, the Rooftop and zone controllers all communicate in real-time. The network connections
are made using the network terminal blocks located on the M2000 controller (see Figure 20).
