GENERAL INFORMATION
PL-VC1000: Independent or Networked Intelligent Zone
Controller
Description
The PL-VC1000 series ProLon zone
controllers use a microprocessor with
proportional and integral action. This
action allows for a precise set-up of
the variable air volume box, either in
a network or independently.
General Behaviour
The ProLon VC1000 controllers are programmable, thus every parameter may be optimized to obtain
the best results for each zone. It is possible to modify the action of each output (heating/cooling (and/or)
On-or-Off/pulsed), the proportional bands, the integration times, the differentials, the operational ranges
and the setpoints. The opening time of the damper can also be configured, thus avoiding any overuse
once fully opened or closed. This also means that the damper can be controlled by more powerful
motors with different opening times. Also, the damper can now be controlled by a self-configuring
Halomo motor, enabling accurate positioning of the damper. The various programming options also
allow a person to modify the unoccupied mode setpoints, the deadbands, the maximum and minimum
setpoints for each zone, as well as the minimum damper position in ventilation mode and in heating
mode for each zone. All these parameters can be modified using the ProLon Focus software or with the
ProLon digital interface (T1000 series).

Operation Sequence
General
The ProLon controller, located on the ventilation box, receives the zone temperature and setpoints from
the room sensor, and optionally the duct temperature from a duct temperature sensor. The controller
then analyzes the received information and commands the damper motor and the different outputs to
respond accordingly.
Occupied Mode
When there is a cooling demand in the zone and the supply temperature is colder than the zone
temperature, the damper opens proportionally to the demand. Once the demand is satisfied, the damper
returns to its minimum ventilation position.
When there is a heating demand in the zone, the controller activates the designated auxiliary heating
outputs. If the zone has a terminal duct heater, the damper opens first to the minimum heating position
and the designated auxiliary heating outputs activate. If the supply temperature is warmer than the zone
temperature, the damper is used as the first heating output and opens proportionally to the demand.
Once the demand is satisfied, the damper returns to the minimum ventilation position.
When the controller has no cooling or heating demand (deadband), and the supply temperature is also
within this deadband, the controller opens the damper to 100% to allow maximum ventilation of the
zone.
The user can modify the setpoints by adjusting the room temperature sensor at all times.
Unoccupied Mode
In unoccupied mode, the damper can be configured to fully open or to operate in a fashion similar to that
of occupied mode. The room temperature setpoints in the unoccupied mode are adjustable.
The Override button located on the room thermostat bypasses the unoccupied mode for a specified
length of time.

Communication Cards
The network communication protocol of the ProLon PL-VC1000 Controller is
adjustable to fit your needs. When there is no communication card installed,
the ProLon controller automatically uses Modbus RTU over RS485 as the
default protocol. The addressing of each card is done by using the seven first
small switches on the addressing dipswitch (see Figure 1). A maximum of
127 units can be addressed on the same network.
The ProLon PL-VC1000 controller offers you a
choice of communication protocols. It is as
simple as choosing the communication card that
corresponds to your desired protocol. For
example, plugging in the Lon card enables Lon
communication. Other cards can be made
available upon request.
When a communication card is installed, the
default Modbus communication protocol is
bypassed (see Figure 2).
BACnet
To enable BACnet communication, no additional communication card is
required! Simply move switch #8 of the addressing dipswitch to the ‘ON’
position to start BACnet MS/TP (RS485) communication.
Jumper to supply power to the RJ45 plug
The RJ45 jumper lets the user select the voltage that will appear on pin #7 of the RJ45 plug. This can be
used to power a device attached to the RJ45 plug, such as the PL-HNI digital interface. NOTE: If
multiple VC1000 controllers are connected together through the RJ45 plug, only one VC1000 should be
supplying power onto the RJ45, otherwise you will be mixing your supply sources and possibly cause
damage. The jumper setups are as follows:

Airflow Sensor (Optional)
Adding an airflow sensor to the ProLon controller lets it regulate the temperature and the airflow into a zone,
independently of the static pressure variations of the system. Two different airflow sensors are offered (see
Figure 3):
Low velocity sensor (0 - 1000 ft/min)
High velocity sensor (0 - 3000 ft/min)

Address Configuration for Networking
A unique address on each controller must be configured 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, 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 on Figure 4 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.

Damper Direction Configuration
The default damper opening direction of a VC1000 VAV controller is counter clockwise (CCW). This
parameter 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. Reversing the Damper Direction
Whenever a VC1000 resets and a jumper is placed on the last
two pins on the far most right of port J11, the damper opening
direction will be inverted (see adjacent image).
A VC1000 can be reset in one of the following ways:
Pressing on the physical RESET button
Cycling power to the device
Please note that in the event of a device reset, a VC1000
VAV controller always performs a damper recalibration first,
where it moves the damper completely to one side and then
completely to the other side. Even if you invert the damper
opening direction, the change will not take effect until after the
calibration period.
2. Once you have finished configuring the damper opening
direction to the setting of your choice, do not forget to
REMOVE the jumper from the last two pins, or the damper
direction will invert itself again and again upon any
subsequent resets of the controller.
To ensure that the damper direction will no longer change,
move the jumper one pin to the left, as depicted in this image:
3. Confirming Damper Direction
The damper opening direction can be visually confirmed by
observing the green “STAT” LED on the VC1000 board after
performing a reset:
“STAT” LED STEADY ON for 3 seconds = COUNTER CLOCKWISE (CCW) OPENING
“STAT” LED PULSES 3 TIMES (ON/OFF) over 3 seconds = CLOCKWISE (CW) OPENING
