Description
The M2000 FlexIO is a general purpose HVAC controller whose inputs and outputs can be individually
configured for use in various applications. Unlike most ProLon controllers, the FlexIO is not aimed at
a specific HVAC sequence or piece of equipment, and instead can be used to perform any outlying
functions that are not usually covered by existing ProLon devices. Outputs can be configured to respond
to a variety of standard HVAC input signal types, ranging from temperatures, pressure, gas and more.
Features
• Many input types available: Temperature, Dry Contact, Pressure, Gas, Humidity
• Configurable names and display options for each input and output
• Configurable scales for pressure and gas inputs accommodates any sensor
• Outputs can act based on any local input, or on data received from a network master
• Can receive up to 8 dierent occupancy states from an NC2000, allowing for versatile lighting control
• Various output logic sequences are available: ON/OFF, PI Loop, Direct or Reverse acting
• Outputs can be interlocked with each other
• Outputs can be automatically overridden based on outside temperature and/or occupancy
• Operates standalone or can be integrated into a ProLon network

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.

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.

REV. 7.2.0 / PL-HRDW-FLX-M2000-EN
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 FlexIO 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.

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 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.

The M2000 FlexIO controller’s inputs can be configured to accept a wide range of signal types. It is
important to note that depending on the chosen signal type, a modification to the input jumper config-
uration may be required (see p.7).
Displayed below are examples of input wiring for most signal types. It is important to also configure the
input appropriately in the controller’s software configuration.
Inputs
Signal: Thermistor
The M2000 FlexIO controller inputs can be used to monitor temperatures. The temperature sensors used
are standard 10kΩ type 3 thermistors (see Figure 10).
The outside air temperature and supply air temperature can optionally be provided by an alternate source,
such as a network master. 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.

The M2000 FlexIO controller inputs can be used to monitor the voltage signal produced by a variety of
transducers (such as pressure, gas, humidity and more). Please refer to Figure 12 for correct wiring.
It is important to ensure that the sensor shares the same common as the M2000 so that there is no 24 VAC
feedback sent back to the controller, which can interfere with the controller’s ability to maintain accurate
analog input readings.

The M2000 FlexIO controller inputs can be used to monitor the current signal produced by a variety of
transducers (such as pressure, gas, humidity and more). Please refer to Figure 13 for correct wiring.
It is important to ensure that the sensor shares the same common as the M2000 so that there is no 24 VAC
feedback sent back to the controller, which can interfere with the controller’s ability to maintain accurate
analog input readings.

The M2000 FlexIO 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
condition. 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 FlexIO controller, all triac outputs produce a 24 VAC live voltage when activated. Note that
all output voltages originate from the same voltage supply that is powering the controller (see Figure 16).
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).
Figure 14 - Wiring example of digital outputs 1
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). The analog outputs can modulate a DC load,
work in ON/OFF mode, or use pulse width modulation.

Power Source & Network
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).
Power Source
Network Communication
The ProLon M2000 FlexIO controller is designed to work standalone or networked with ProLon control-
lers. When networked, it can receive the occupancy status, outside air and supply air temperatures in
real-time. The network connections are made using the network terminal blocks located on the M2000
controller (see Figure 17).
