General Behaviour Although fully configurable, the ProLon M2000 Heatpump controller uses pre-established control sequences 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...
Operating Sequence General The ProLon M2000 Heatpump controller receives readings from three different temperature sensors: outside air, return air and supply air. It operates on a configurable schedule using an internal real-time clock. Also, as a Master device, it receives data from the zone controllers sent on the network bus. The...
PL-M2000 SERIES HEATPUMP HARDWARE GUIDE www.proloncontrols.com Unoccupied Mode The fan can be configured to operate in intermittent mode. When there is a cooling or heating demand from any single zone, the Rooftop controller will activate the fan and the necessary cooling or heating outputs as long as all temperature limits, delays and other related parameter are respected.

HBEAT: When this LED is blinking, the microchip is active and the controller’s program is • running (normal). When this LED is ON and steady, the M2000 is inactive and the microchip is awaiting programming (you must use ProLon’s Focus software to reprogram the microchip). STAT: Reserved. •...
PL-M2000 SERIES HEATPUMP HARDWARE GUIDE www.proloncontrols.com AO1: The intensity of the LED represents the voltage present on analog output 1. • DO5: Represents the activity of digital output 5. • DO4: Represents the activity of digital output 4. • DO3: Represents the activity of digital output 3.
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.
PL-M2000 SERIES HEATPUMP HARDWARE GUIDE www.proloncontrols.com Input and Output Identification All the inputs and outputs of the M2000 use pluggable screw type terminal blocks with elevator style clamping, which make connections easier and more secure. For incoming communication from a remote computer or network controller, dual RJ45 type connectors are available in parallel with screw type terminal blocks.
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...
PL-M2000 SERIES HEATPUMP HARDWARE GUIDE www.proloncontrols.com INPUTS Temperature Sensors The M2000 Heatpump controller has three analog inputs that monitor outside air, supply air and return air 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.
PL-M2000 SERIES HEATPUMP HARDWARE GUIDE www.proloncontrols.com Room Sensors The M2000 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.
PL-M2000 SERIES HEATPUMP HARDWARE GUIDE www.proloncontrols.com Dry Contact for Clogged Filter or Schedule Override Analog input 4 on the M2000 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 7 to see proper connection.
PL-M2000 SERIES HEATPUMP HARDWARE GUIDE www.proloncontrols.com Static Pressure and CO Analog inputs 8 and 9 on the M2000 heatpump controller are dedicated to the CO and static pressure sensors, respectively. By default, a 4-20 mA signal is expected for the CO input and a 0-5 VDC or 1-5 VDC signal is expected for the static pressure input.
The M2000 Heatpump 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 HEATPUMP HARDWARE GUIDE www.proloncontrols.com Typical Connection of Triac Outputs 1 to 5 On the M2000 Heatpump 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.
Figure 12: Connecting the 24VAC power source Network Communication The ProLon M2000 Heatpump controller is designed to work with the ProLon zone controllers (except Heatpump Standalone controller). When they are networked, the M2000 and zone controllers all communicate in real-time. The network connections are made using the network terminal block located on the M2000 controller (see Figure 13).
