Description
The EVCB Series is a combination controller and thermostat with
support for networked communications via the BACnet MS/TP or
Modbus protocol. The Networkable VAV Controller is designed for
simple and accurate control of any variable air volume box in a
number of zone control configurations. Its field configurable
algorithms enable versatile implementation of required control
sequences.

Mechanical Installation
1. Manually close the damper blades and position the actuator
to 0º or 90º.
2. Slide the actuator onto the shaft.
3. Tighten the nuts on the “U” bolt to the shaft with an 8mm
wrench to a torque of 60 in-lb [6.7 Nm].
4. Slide the mounting bracket under the actuator. Ensure free
movement of the slot at the base of the actuator. Place the
bracket pin at mid distance of the slot.
5. Affix the bracket to the ductwork with #8 self-tapping screws.
Do not press the clutch when the actuator is powered.

Mounting Instructions
CAUTION: Remove power to avoid a risk of malfunction.
A. Remove the captive screw that’s holding the base and the front cover of the unit together.
B. Lift the front cover of the unit to separate it from the base.
C. Pull all wires through the holes in the base.
D. Secure the base to the wall using wall anchors and screws (supplied). Make the appropriate connections.
E. Mount the control module on the base and secure using the screw.
BACnet or Modbus Address DIP Switch (DS1)
MAC address for communication, are selectable by DIP switch using binary logic. If you do not change device instance in program mode, it will be
automatically modified according to the MAC address.
Note: Avoid using addresses above 246 when selecting Modbus MAC address.

Wiring
We strongly recommend that all Neptronic products be wired to a separate grounded transformer and that transformer shall service
only Neptronic products. This precaution will prevent interference with, and/or possible damage to incompatible equipment.
