General Information

The ProLon PL-M2000 RTU Rooftop controller is a microprocessor-based controller designed to operate

rooftops or other mechanical HVAC systems. It uses PI (Proportional-Integral) control loops and acts as a

master when used on a network with ProLon zone controllers.

Although fully configurable, the ProLon M2000 Rooftop controller uses pre-established control sequen-

ces or ''profiles'' to operate specific HVAC equipment with dedicated output functions. These can be fully

optimized to obtain the best results for each type of system. Numerous parameters enable the mod-

ification or fine tuning of the fan, the cooling outputs, the action of the heating outputs (On-or-Off /

pulsed / modulating), the bypass or VFD and outside air dampers, the CO2 levels, the proportional bands,

integration times, differentials, operational ranges, setpoints and a whole range of limits and safeguards.

The various programming options also allow the user to modify the schedule, unoccupied mode settings,

morning warm-up and supply air pre-heating sequences as well as the network demand control strategy

best suited for the building space it is controlling. All these parameters can be accessed by using the

ProLon Focus software.
