Page 3: General Information
The various programming options also allow the user to modify the lead-lag sequences, conditions for pump activity and the influence of schedules or other data received over the network. All these parameters can be accessed and modified by using the ProLon Focus software. -
Page 4: Operating Sequence
In addition to the temperature sensors, it also has inputs for proof of operation of the pumps. It can receive data from ProLon master controllers such as outside temperature, occupancy, or the average heating request of the building. The controller then analyzes all the data and activates the appropriate outputs to respond accordingly, within parameters set by the temperature sensors and other safety limits. -
Page 5: Follower Pump Sequence
PL-M2000 SERIES BOILER HARDWARE GUIDE www.proloncontrols.com Follower Pump Sequence This sequence is intended for hydronic systems where there is a primary and secondary loop. The primary pump is activated based on outside temperature or upon a call for heating, or both. The secondary pump will be activated simply when there is proof of operation of the primary pump. -

Figure 2: Location of the INTERNAL jumpers INT: These are the jumpers for the bias and terminating resistors used for the interface communication bus. See the ProLon network guide for information about bias and terminating resistors. NET: These are the jumpers for the bias and terminating resistors used for the network communication bus. -
Page 10: Input And Output Identification
The M2000 Boiler Controller has 2 separate communication ports offering the same functionality on each. Both act as ports for incoming Modbus communications from other ProLon devices or interfaces, such as a Network Controller or remote computer with ProLon Focus software. -
Page 11: Addressing Dipswitch Configuration For Network Communication
The example in Figure 3 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 3: Addressing Dipswitch Montréal... -
Page 12: Inputs
PL-M2000 SERIES BOILER HARDWARE GUIDE www.proloncontrols.com INPUTS Temperature Sensors The M2000 Boiler controller has three analog inputs that monitor outside air, supply water and return water temperatures (see Figure 4) and will integrate these readings into its control sequence. The sensors used are standard 10k type thermistors that share a single common connection. -
Page 13: Proof Of Pumps
PL-M2000 SERIES BOILER HARDWARE GUIDE www.proloncontrols.com Proof of Pumps The M2000 has two analog inputs dedicated to the proof of pump signals. Please refer to Figure 5 to see how to correctly connect them. To indicate proof of pump, the contact must be closed. If no proof of pump signal is available, you must short the corresponding input, or else the controller will interpret the absence of signal as a pump malfunction and no heating action will be taken. -
Page 14: Outputs
The M2000 Boiler 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. -

PL-M2000 SERIES BOILER HARDWARE GUIDE www.proloncontrols.com Typical Connection of Triac Outputs 1 to 5 On the M2000 Boiler 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. Consequentially, only the live side of the output connections are usually needed;... -
Page 16: Power Source & Network
Figure 8: Connecting the 24VAC power source Network Communication The ProLon M2000 Boiler controller is designed to work standalone or networked with ProLon master controllers. When networked, the master transmits the occupancy status, outside temperature and math demand in real-time. The network connections are made using the network terminal block located on the M2000 controller (see Figure 9). -
