Description
The C1050 FlexIO is a general purpose HVAC controller whose inputs and outputs can be individually congured for use
in various applications. Unlike most Prolon controllers, the FlexIO is not aimed at a specic 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 congured to respond to a variety of standard HVAC input signal types, ranging from tempera-
tures, pressure, gas and more.
Features
• Many input types available: Temperature, Dry Contact, Pressure, Gas, Humidity
• Congurable names and display options for each input and output
• Congurable 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 5 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, Pulsed
• 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 C1050 has various LEDs which are linked to dierent functions and outputs of the controller. Each LED is individually
identied to help the user make a quick visual diagnostic of the controller’s activity and status.
Figure 3 - Addressing Dipswitches
LEDs
Address Configuration for Networking
Aunique address on each controller must be congured by setting the rst 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, 64 respectively). The
value of each switch that is in the ON position is added together to form the numerical address of the controller.
The example below shows the switches 1, 2 and 4 on the ON position. So the corresponding values are 1, 2 and 8, giving
an address sum of 11. (1+2+8=11)
The Prolon network allows a maximum of 127 addresses, therefore 127 controllers.

All the inputs and outputs of the C1050 use pluggable screw type terminal blocks with elevator style clamping, which
make connections easier and more secure.
The C1050 FlexIO Controller has two separate communication ports oering 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.

Inputs
For the C1050 Digital Input, it can only accept contact signals.
Displayed below are examples of input wiring for most signal types. It is important to also congure the input appropri-
ately in the controller’s software conguration.
Signal: Thermistor
The C1050 FlexIO controller inputs can be used to monitor temperatures. The temperature sensors used are standard
10kΩ type 3 thermistors.
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.
Analog Input
Figure 5 - Analog input
The C1050 series controllers are equipped with three general purpose analog inputs. These inputs can be congured to
receive signals of the following types:
• Thermistor (Ω) •0-5V
• 4 -20mA •0-10V
When a thermistor is used, the thermistor must be 10KΩ TYPE 3.
Each C1050 analog input is equipped with a fast-switching barrier diode to protect against surges and short circuits.
By default, the C1050-CHL analog inputs are set up for thermistor mode. The input signal mode can be changed by set-
ting jumpers U1, U2 and U3, situated inside the casing, in the desired position:

The C1050 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 8 for correct wiring.
Note: When nothing is connected, the input will read the maximum possible reading.
It is important to ensure that the sensor shares the same common as the C1050 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 C1050 FlexIO controller inputs can be used to monitor the current signal produced by a variety of transducers (such

to Figure 10 for correct wiring.
It is important to ensure that the sensor shares the same common as the C1050 so that there is no 24 VAC feedback sent

The C1050 FlexIO controller contains 5 customizable outputs; four triac ON/OFF outputs (24VAC) and one analog output
(0-10VDC). Output conguration is performed via the Prolon Focus software.
An integrated resettable fuse protects each of the outputs of the C1050 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 round and yel-
low-colored which, upon a short circuit condition, will heat up and change to orange. When the faulty wiring or circuit is
xed, the fuse will automatically reset and allow current to ow through the output again.

Outputs
The digital triac outputs are congurable (SOURCE/SINK) via a switch located on the board. Simply move the switch to
obtain either a SOURCE active output (1) or a SINK passive output (2).

The Prolon C1050 controller is powered by a 24 VAC power source connected using the "COM" terminal and the "24 VAC"
terminal. The common for all inputs and outputs are the same as the power source’s common (exception: when an out-
put is set to passive, the common for this output will not correspond to the power source common). All output power
sources also originate from the controller’s power source.

Network Communication
The Prolon C1050 controller works autonomously or networked. When networked, it will communicate in real-time with
other controllers. The C1050 controller’s default communication protocol is Modbus RTU over RS485. The addressing is
done with the addressing dipswitch located on the C1050 board (see Figure 3). The network connections are made using
the NET terminal block located on the Prolon C1050 controller.
