General Installation Requirements
For proper installation and subsequent operation of the controller, pay
special attention to the following recommendations:
- It is recommended that the controller(s) be kept at room
temperature for at least 24 hours before installation to allow any
condensation that may have accumulated due to low temperature
during shipping/storage to evaporate.
- Upon unpacking the product, inspect the contents of the carton for
shipping damages. Do not install damaged controllers.
- Avoid areas where corroding, deteriorating or explosive vapors,
fumes or gases may be present.
- Allow for proper clearance around the controller’s enclosure, wiring
terminals, and service pin (see Figure 14) to provide easy access
for hardware configuration and maintenance, and to ventilate heat
generated by the controller. Remember to record the 12-character
®
Neuron
ID located on a sticker on top of the device (shown on a
sticker below the barcode), for later commissioning. When installed
in an enclosure, select one that provides sufficient surface area to
dissipate the heat generated by the controller and by any other
devices installed in the enclosure. A metal enclosure is preferred. If
necessary, provide active cooling for the enclosure.
- The controller’s datasheet specifies the power consumption
(amount of heat generated), the operating temperature range, and
other environmental conditions the controller is designed to operate
under.
- Ensure that all equipment is installed according to local, regional,
and national regulations.
- Do not drop the controller or subject it to physical shock.
- If the controller is used and/or installed in a manner not specified by
Distech Controls, the functionality and the protection provided by
the controller may be impaired.

General Wiring Recommendations
Controller Dimensions & Components
Figure 2: VAVS-O, VAVS, VAV & VVTS series dimensions
Turn off power before any kind of servicing.
- All wiring must comply with electrical wiring diagrams as well as
national and local electrical codes.
- To connect the wiring to a controller, use the terminal connectors.
Use a small flat screwdriver to tighten the terminal connector
screws once the wires have been inserted.
- Power type cables (i.e. for power, 2- and 3-wire voltage and current
inputs and outputs, as well as triac outputs) should be kept apart
from other types of wiring to avoid any ambient noise transmission
to other wires.
- The board connectors accept wires or flat cables ranging from 22 to
14AWG (0.644 to 1.630mm diameter) per pole. However, power
cables must be between 18 and 14AWG (1.024 to 1.630mm
diameter).
- Do not connect the universal inputs, analog/digital outputs or
common terminals to earth or chassis ground (unless stated
otherwise).
- Keep all wires away from high speed data transmission cables (for
example, Ethernet, etc.).
- Keep input and output wiring in conduits, trays or close to the
building frame if possible.

controller using the integrated mounting bracket(s) and
screw(s) that are provided with the controller.
Each controller is specially designed for easy installation either directly
on an air duct or in a panel by using the integrated mounting collar and
the screw that is provided with the controller. This mounting
arrangement opposes the torque applied to the damper shaft. Mount
the controller as follows:
1. Orient the controller into position on to the damper shaft so that
wiring connections are easily accessible. The controller must be
fitted onto the shaft such that the base of the controller is parallel
to the VAV box (perpendicular to the damper shaft). If the damper
shaft has an external bushing that prevents the controller from
being mounted flush to the side of the VAV box, use a spacer of
the same thickness to compensate and to ensure the controller is
at a right-angle to the shaft to prevent binding.
controller’s electronics. When the VAV box air supply is
below 10°C (50°F), ensure that any condensation from the
damper shaft or from the VAV box does not enter the
controller’s electronics. Under these conditions, mount the
controller vertically above the damper shaft so that any
condensation from the damper shaft will fall away from the
controller. Further countermeasures
2. Using a power screwdriver, attach the controller to the VAV box
with the screw provided with the controller through the controller’s
mounting bracket slider. Otherwise, mark the screw’s position on
the VAV box with a punch and then drill a hole into the VAV box.
Then attach the controller to the VAV box with the screw provided
with the controller.
the threads. Make sure the screws do not interfere with
3. Find the damper position by the marking typically found on the end
of the damper shaft.
Figure 6: Typical Damper Shaft End Marking
4. Determine the direction required to close the damper: Clockwise
(CW) or Counterclockwise (CCW). Turn the damper shaft with a
pair of pliers to fully close the damper for 90° boxes or fully open
the damper for 45° or 60° boxes.
5. Press and hold down the Actuator Clutch for Manual Adjustment
button (see Figure 4), and turn the controller’s shaft coupler until it
touches the mechanical end-stop to either the fully closed position
(90° boxes) or the fully open position (45° and 60° boxes).
6. For 90° VAV boxes: If the damper closes CCW, turn the coupler to
the CCW mechanical stop limit. If the damper closes CW, turn the
coupler to the CW mechanical stop limit. The open mechanical
stop is factory preset for 90° boxes.
For 45° and 60° VAV boxes: The mechanical stops must be set for
both the fully closed and fully open damper positions. By installing
the controller at the fully open position, the controller provides the
open mechanical stop for 45° and 60° boxes. The closed damper
seal provides the fully closed stop.
7. Tighten the U-Bolt clamp on to the damper shaft using an 8 mm
(5/16 in.) wrench or socket. Tighten the bolts between 11 and 15
N·m (100 and 130 lb·in).
8. Test for free damper shaft movement: Press and hold down the
Actuator Clutch For Manual Adjustment button and manually turn
the actuator coupling to be certain that the actuator can rotate from
full closed to full open positions without binding.
9. Connect the VAV box’s flow sensor tubing to the controller’s
Pressure Sensor Inputs. Create a condensation trap in the
pneumatic tubing by forming it into a vertical loop.
10. Finalize the installation by rotating the damper to the full open
position.
damper is at the full open position before starting the air
handler. Failure to rotate the damper to its full-open position
may result in damage to the Variable Air Volume (VAV) box

Voltage: 24VAC/DC; ± 15%, Class 2
This is a Class 2 Product. Use a Class 2 transformer only
The Network Guide provides extensive information and requirements
for powering a VAV that uses a LONWORKS network for
communications. It can be downloaded from our website.
When calculating a controller’s power consumption to size the 24VAC
transformer, you must also add the external loads the controller is
going to supply, including the power consumption of any connected
subnet module (for example, for Allure™ Series Communicating
Sensors). See the room device calculator spreadsheet available for
download from our website to determine the power requirements for
the ECL-VAV model: VAV-Smart Room Control Device
Calculator.xlsm
It is recommended to wire only one controller per 24VAC transformer.
If only one 24VAC transformer is available, determine the maximum
number of daisy-chained VAVs that can be supplied on a single power
cable supplied by a 100 VA transformer, according to the controller’s
expected power consumption including external loads, the cable’s wire
gauge, and the total cable length from the following table. Any
installation condition that is outside of the parameters of Table 1
should be avoided.

Troubleshooting Guide
Controller is powered but does not turn on
Fuse has blown
Disconnect the power. Check the fuse integrity. Reconnect the power.
Power supply polarity
Verify that consistent polarity is maintained between all controllers and the transformer. Ensure that the 24VCOM terminal
of each controller is connected to the same terminal on the secondary side of the transformer. See Figure 8.
Controller cannot communicate on the LONWORKS network
Absent or incorrect supply voltage
1. Check power supply voltage between 24VAC ±15% and 24VCOM pins and ensure that it is within acceptable limits.
2. Check for tripped fuse or circuit breaker.
Overloaded power transformer
Verify that the transformer used is powerful enough to supply all controllers.
Network not wired properly
Double check that the wire connections are correct.
Absent or incorrect network termination
Check the network termination(s).
Too many Allure EC-Smart-Vue Sensors are
providing network access
Disable the Net to Subnet Port Settings jumpers on all controllers (for jumper location, see Figure 9). If communications
are re-established, re-enable only a few Allure EC-Smart-Vue sensors to have network access.
Controller communicates well over a short network, but does not communicate on large network
Network length
Check that the total wire length does not exceed the specifications of the Junction Box and Wiring Guideline for Twisted
Pair LONWORKS Networks.
Wire type
Check that the wire type agrees with the specification of the Junction Box and Wiring Guideline for Twisted Pair
LONWORKS Networks.
Network wiring problem
Double check that the wire connections are correct.
Absent or incorrect network termination
Check the network termination(s). Incorrect or broken termination(s) will make the communication integrity dependent
upon a controller’s position on the network.
Extra capacitance
Make sure that no extra capacitance is being connected to the network other than the standard FTT circuit and a
maximum of a 3 meter stub (in bus topology).
Number of controllers on network segment
exceeded
The number of controllers on a channel should never exceed 64. Use a router or a repeater in accordance to the Junction
Box and Wiring Guideline for Twisted Pair LONWORKS Networks .
Network traffic
Query node statistics to check for errors.
Use a LONWORKS protocol analyzer to check network traffic.
Hardware input is not reading the correct value
Input wiring problem
Check that the wiring is correct according to this manual and according to the peripheral device’s manufacturer.
Open circuit or short circuit
Using a voltmeter, check the voltage on the input terminal. For example, for a digital input, a short circuit shows
approximately 0V DC and an open circuit shows approximately 5V DC.
Configuration problem
Using EC-gfxProgram, check the configuration of the input. Refer to the controller’s user guide for more information.
Over-voltage or over-current at an input
An over-voltage or over-current at one input can affect the reading of other inputs. Respect the allowed voltage / current
range limits of all inputs. Consult the appropriate datasheet for the input range limits of this controller.
Hardware output is not operating correctly
Fuse has blown (auto-reset fuse)
Disconnect the power and outputs terminals. Then wait a few seconds to allow the auto-reset fuse to cool down. Check
the power supply and the output wiring. Reconnect the power.
Output wiring problem
Check that the wiring is correct according to this manual and according to the peripheral device’s manufacturer.
Configuration problem
Using the controller configuration plug-in or wizard, check the configuration of the output. Refer to the controller’s user
guide for more information.
0-10V output, 24VAC powered actuator is not
moving.
Check the polarity of the 24VAC power supply connected to the actuator while connected to the controller. Reverse the
24VAC wire if necessary. Check the jumper settings for the external power supply as shown in Table 3.
Wireless devices not working correctly
Device not associated to controller
Using EC-gfxProgram, check the configuration of the input. Refer to the device’s user guide for more information.
Power discharge
1. Recharge device with light (if solar-powered) or replace battery (if battery-powered),
2. Ensure sufficient light intensity (200lx for 4 hours/day).
Device too far from the Wireless Receiver
Reposition the device to be within the range of the Wireless Receiver. For information on typical transmission ranges,
refer to the Open-to-Wireless Solution Guide.
Configuration problem
Using the device configuration plug-in or wizard, check the configuration of the input. Refer to the Wireless Battery-less
Sensors and Switches Solutions Guide for more information.
Flow sensor is not giving proper readings
Tubing connection problem
1. Make sure that the tubing is installed properly and that the tubing is not bent.
2. Verify that the high and low pressure sensors are not inversed.
Controller is not calibrated properly
Recalibrate the controller. Refer to the controller’s user guide for more information.
Damper is not opening or closing properly
Mechanical stops not in proper position
The two mechanical stops must be positioned to stop the damper motion when it is completely closed and completely
opened. The mechanical stops can be moved by increments of 5°.
Controller in Override
Set the Override to OFF in the wizard.
Rx/Tx LEDs
RX LED not blinking
Data is not being received from the LONWORKS data bus.
TX LED not blinking
Data is not being transmitted onto the LONWORKS data bus.
