PL-C1000 VAV Zone Controller Description The Prolon C1000 series zone controllers are designed for variable air volume zoning systems. The built-in microprocessor offers precise digital control to maximize performance. The outputs and control sequences are all fully configurable, either locally or remotely, using free software or from the digital room sensor.
Operating Sequence General The Prolon controller, located on the VAV box, receives the zone temperature and setpoints from the zone sensor, and optionally the duct temperature from a duct temperature sensor. The controller then analyzes the information and commands the damper actuator and the different outputs to respond accordingly.

LEDs The C1000 has various LEDs which are linked to different functions and outputs of the controller. Each LED is individually identified to help the user make a quick visual diagnostic of the controller’s activity and status Red light: Sending to INT port Green light: Reception from INT port Red light: Sending to NET port...

The default damper opening direction of a C1000 VAV controller is counter clockwise (CCW). This parame- ter can be modified in two different ways. The first is by using a digital interface or Prolon Focus software to manually change the setting. The second is to use the following method: 1.
The C1000 VAVController has two 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.

Multi-Function Analog Input The C1000 has a multi-function analog input. The function of this input varies depending on the con- figuration that is setup using the Prolon Focus software. By default, this input is used as a supply air temperature input.

To indicate occupied mode, the contact must be open. To indicate unoccupied mode, the contact must be closed. Note that if a C1000 controller is part of a network that includes a Prolon Master controller (RTU, HP or other), an individual contact per C1000 may be unnecessary because all zone controllers share the occu- pancy status sent on the network by that Master.
Outputs The C1000 series controllers are equipped with four configurable 24VAC triac digital output and an analog 0-10VDC output to control a wide variety of equipment. All outputs are fully configurable in either heat- ing or cooling mode, can function in pulsed or ON/OFF mode, and much more. The entire setup for each output is fully customizable via the Prolon Focus software or the Prolon T1000 digital sensor.
Configuration of Digital Outputs 1 to 4 Outputs 1 to 4 are configurable via switches located on the C1000 board. Simply move the switch to obtain either an active output (1) or a passive output (2). 1) Switch position to obtain an active output (see Figure 17): Switch for Output 4 24 VAC Output (pulsed or ON/O )
2) Passive outputs. The C1000 opens and closes a contact to allow an external source to power the load (see Figure 20). 24 N External 24 V Figure 20 - Connection of Passive Outputs 3 and 4 Typical Connection of the Analog Output Two types of configuration are possible: 1) The C1000 powers the load and provides a control signal (see Figure 20) 24 VAC power...
Power Source / Network Power Source The Prolon C1000 controller is powered by a 24 VAC power source (Class 2) connected using the "COM" terminal and the "24 VAC" terminal (see Figure 16). The common for all inputs and outputs are the same as the power source’s common (exception: when an output is set to passive, the common for this output...
