General Information
Description
The Prolon PL-M2000 Air Make Up controller is a microprocessor-based controller designed to operate
a variety of different make-up air units and systems. It features a variety of control strategies, including
outdoor temperature reset, building pressure control, CO2 control, safety limits and more.
General Behavior
Although fully configurable, the Prolon M2000 Air Make Up controller monitors dedicated inputs and
uses pre-established control sequences to drive dedicated outputs to control standard Make Up Air
equipment. These sequences can be fully optimized to obtain the best results for each type of system.
Numerous parameters enable the modification or fine tuning of the summer and winter sequences,
lockout mode, building pressure and CO2 control, the target supply temperature, the proportional bands,
integration times, differentials, operational ranges, setpoints and a whole range of limits and safeguards.
All these parameters can be accessed and modified by using the Prolon Focus software.

Operating Sequence
General
The Prolon M2000 Air Make Up controller follows a strict activation sequence before heating or cooling
actions can be taken. The sequence begins with the exhaust fan. When proof of exhaust fan is obtained,
the outside air damper is opened. When proof of damper opening is obtained, the fan is activated. Finally,
when proof of fan is obtained, heating or cooling action is authorized.
Heating and cooling action is decided based on the seasonal sequences defined below.
The controller continuously monitors the inputs and will activate or deactivate the appropriate outputs
accordingly, within parameters set by the temperature sensors and other safety limits. Under specific
circumstances, the controller will enter Lockout mode, wherein all outputs are deactivated (except the
exhaust output). Lockout mode is typically activated when proof of fan or damper is not obtained, or if
the supply air low limit is triggered to frequently. To escape lockout mode, a user must press and hold the
manual reset button for 3 seconds.
Summer Sequence
The summer sequence is activated when the outside temperature is above a configurable setpoint. When
a proof of fan signal is obtained, cooling action is authorized.
Cooling action can either be in the form of single or dual stages of ON-OFF cooling. Cooling action can
either be based on zone demand or on the current outside temperature.
When cooling action is demand-based, stages are first authorized based on outside temperature, and
then activated when there is sufficient demand. Demand is generated by a PI (proportional/integral) loop
based on current zone temperature versus current zone setpoints.
When cooling action is based on outside temperature, the cooling stages will activate and deactivate
based on configurable outside temperature setpoints.
Winter Sequence
The winter sequence is activated when the outside temperature is below a configurable setpoint. When
a proof of fan signal is obtained, the heating authorization output is activated.
Heating action comes in the form of modulating heating which aims to reach a target supply setpoint.
The supply setpoint can either be based on zone demand or on the current outside temperature.
When target supply setpoint is demand-based, a supply reset scale is available for configuration in the
Prolon Focus software. Demand is generated by a PI (proportional/integral) loop based on current zone
temperature versus current zone setpoints.
When target supply setpoint is based on outside temperature, a supply reset scale is available for
configuration in the Prolon Focus software.
Mid-Season Sequence
The mid-season sequence is activated when the outside temperature is in-between the configurable
activation setpoints of the winter and summer sequences. In this sequence, no heating or cooling actions
are taken. Only ventilation occurs. The heating authorization output is also off.

HAND/OFF/AUTO Switches
Jumpers
Each output on the M2000 has a dedicated switch that lets the user manually override the activity of the
output. “HAND” mode (switch at rightmost position) fully activates the output (24 VAC for digital outputs,
10VDC for analog outputs). “OFF” (switch at center) deactivates the output and “AUTO” (switch at left)
returns control of the output to the program in the M2000’s microchip.
The M2000 has jumpers that are externally accessible (see Figure 3), as well as jumpers that are on the
lower internal board (see Figure 4), that allow for configuration of various hardware elements.
• 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.
(See Figure 5)
• NET: These are the jumpers for the bias and terminating resistors used for the network communication
bus. See the Prolon network guide for information about bias and terminating resistors.
(See Figure 5)
• AI 1 - 9: These jumpers allow the user to select the signal mode of the associated analog input.

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.
The M2000 Air Make Up 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.
The “INT” Port (see below) offers dual RJ45 type connectors in parallel with screw type terminal blocks.
The RJ45 connectors allow the use of premade CAT5 cables for simple plug-and-play RS485 communica-
tion. These RJ45 connectors follow the Modbus pinout specification for RS485 communication.

Addressing Dipswitch Configuration for Network Communication
For proper communication, a unique address must be configured on each controller by setting the first
7 switches on the addressing dipswitch to the desired value.
These switches are numbered from 1 to 7 and represent a binary value from 1 to 64 (1, 2, 4, 8, 16, 32, and
64 respectively). The last switch (#8) is reserved. The value of each switch that is in the ON position is
added together to form the numerical address of the controller.
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.

Inputs
Temperature Sensors
The M2000 Make Up Air controller has three analog inputs that monitor supply, outside and zone air
temperatures (see Figure 10) and will integrate these readings into its control sequence. The sensors used
are standard 10k type 3 thermistors that share a single common connection.
The outside air temperature can be also be provided by an alternate source. If a network controller
is present on the network, it can retrieve the outside temperature reading from one controller and
distribute it to any other controllers on the network.

Building Pressure or CO
Proof of Action
Analog input 9 on the M2000 Make Up Air controller is dedicated to a CO2 or building pressure sensor.
By default, a 4-20 mA signal is expected for the CO2 input and a 0-5 or 1-5 VDC signal is expected for the
pressure input. However, this can be modified using the internal jumpers (see p.9). Please refer to Figure
11 for correct wiring.
The M2000 has four inputs dedicated to proof of action signals. Please refer to Figure 12 to see how to
correctly connect them. To indicate proof of a certain action, the corresponding contact must be closed.
If no proof of action signal is available for a given action, you must short the corresponding input, or else
the controller will interpret the absence of the signal as a malfunction and halt the rest of sequence.

Manual Reset
The M2000 Make Up Air Controller has an input dedicated to the manual reset signal. Please refer to
Figure 13 to see how to correctly connect it. Whenever the controller has entered lockout mode, it is
required to activate the manual reset switch (close the contact) for 3 seconds to exit lockout mode.

Outputs
Output Specifications
The M2000 Make Up Air 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. This protection will cut the current to the output as soon as an overload condition is detected.
The fuse is a round, yellow-coloured PTC that will change to orange and heat up on an overload condi-
tion. Once power has been removed from the M2000, the fuse will cool down and automatically reset. Fix
the faulty wiring and you will be able to activate the output once again.

Typical Connection of Triac Outputs 1 to 5
Typical Connection of Analog Outputs 1 to 3
On the M2000 Make Up Air 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; these are on the top
row (see Figure 14). The bottom row is the common (GND).
For all analog outputs, the common is found on the bottom row terminal blocks, and the active signals
are found on the top row terminal blocks (see Figure 15). Analog output 2 is configured to control a 10
VDC On/Off relay. Analog outputs 1 and 3 can only modulate a DC load (0-10 VDC, 2-10 VDC).

Power Source & Network
Power Source
Network Communication
The M2000 controller is powered by a 24 VAC power supply (class 2) by connecting the common (’’C’’ wire)
to the "COM" terminal and the live (‘’R’’ wire) to the "24 VAC" terminal (see Figure 16). The common for all
inputs and outputs is the same as the power source’s common. All output power sources also originate
from the source transformer (class 2).
The Prolon M2000 Make Up Air controller is designed to work standalone or networked with Prolon con-
trollers. When networked, it can receive the occupancy status and outside temperature in real-time. The
network connections are made using the network terminal blocks located on the M2000 controller (see
Figure 17).
