Page 4: General Information
PL-M2000 Rooftop Controller Description 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. -
Page 5: Operating Sequence
Operating Sequence General The ProLon M2000 RTU Rooftop controller receives readings from five different temperature sensors: outside air, return air, supply air, mixed air and zone air. In addition to the temperature sensors, it also has inputs for the static pressure, CO2 levels and proof of fan. It operates on a configurable schedule using an internal real time clock. -

The example in Figure 9 shows the switches 1, 2 and 4 in the ON position. Therefore, the corresponding values are 1, 2 and 8, giving an address sum of 11. The ProLon network allows a maximum of 127 addresses; therefore 127 controllers. Figure 9 - Addressing Dipswitch... -
Page 11: Inputs
Inputs Temperature Sensors The M2000 Rooftop controller has four analog inputs that monitor outside air, supply air, return air and mixed air temperatures (see Figure 10) and will integrate these readings into its control sequence. The sensors used are standard 10k type thermistors that share a single common connection. Alternatively, the supply air temperature can be retrieved from a zone controller that has its own supply sensor and belongs to the M2000’s network. -
Page 12: Room Sensors
Room Sensors The M2000 RTU can receive the setpoint and temperature from a specific room when a PL-RS analog thermostat is connected to it. The M2000 will then automatically integrate this information into its control sequence. The setpoint may also simply be set by software. The PL-RS series room sensors are connected using a 3-conductor cable (see Figure 11). -

Dry Contact for Clogged Filter or Schedule Override Analog input 4 on the M2000 RTU can also be configured as a dry contact input for either a clogged filter sensor or as a schedule override input. Please refer to Figure 13 to see proper connection. •... -
Page 14: Outputs
The M2000 Rooftop controller contains 8 customizable outputs; five triac ON/OFF outputs (24VAC) and three analog outputs (0-10VDC). Output configuration is performed via the ProLon Focus software. An integrated resettable fuse protects each of the outputs of the M2000 against current surges and short circuits. -
Page 15: Typical Connection Of Triac Outputs 1 To 5
Typical Connection of Triac Outputs 1 to 5 On the M2000 Rooftop controller, all triac outputs produce a 24 VAC live voltage when activated. Note that all output voltages originate from a single voltage supply: the equipment’s transformer. Consequen- tially, only the live side of the output connections are usually needed; these are on the top row (see figure 15). -

DMUX-4J Connection on Digital Output 2 for 3 or 4 Stage Cooling When 3 or 4 stages of cooling are required, the M2000 Rooftop controller must be equipped with a DMUX-4J. The DMUX-4J input is only connected to Digital Output 2 on the M2000 Rooftop controller. The DMUX-4J must be configured to “Sequenced Relay Control”... -
Page 17: Pta2 Connection On Digital Output 2 For Analog Cooling
PTA2 Connection on Digital Output 2 for Analog Cooling When proportional modulating cooling is required, the M2000 Rooftop controller must be equipped with a PTA2 v.1. interface to create an analog 0-10Vdc output signal. The PTA2 input is connected to Digital Output 2 on the M2000 Rooftop controller. -

Figure 19 - Connecting the 24VAC Power Source Network Communication 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). -
