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.

Operation Menus
This menu is accessible through normal operation mode. The Mode Selector jumper (JP1) of the thermostat must be set to the
“RUN” position (Operation Mode). Refer to Wiring on page 6.
7. Press the [*] and [] buttons simultaneously for 5 seconds. The “Enter Password” screen appears.
8. Enter the password within 1 minute by using the arrow keys to increase or decrease the value and the [*] and [] buttons to
toggle between the digits.
a. Password 372 = Temperature Offset Menu
b. Password 637 = Network Settings Menu
c. Password 757 = Airflow Balance Mode
9. If you enter the wrong password, the thermostat displays “Eror” and returns to Operation Mode. The thermostat will return to
normal mode if you navigate through the entire menu and do not make any selection, or if you do not press any key for 5
minutes. The changed values will be saved automatically.
Menu 372 –Temperature Offset
1. “tS1”(temperature sensor offset)
Range:
Offset:
Increment:
10 to 40ºC [50 to 104ºF]
Max ± 5ºC
0.1ºC [0.2ºF]
Compare the displayed temperature reading with a known value from a thermometer. To offset or calibrate the sensor, use the
arrows key to set the desired temperature reading. This is useful for thermostats installed in areas where the temperature read
is slightly different than the room’s actual temperature. For example, a thermostat placed right under the air diffuser.
If the thermostat is set to use an external temperature sensor (EtS), the thermostat displays “OFF”.
2. “Ets" (external temperature sensor offset)
Range:
Offset:
Increment:
0 to 50ºC [41 to 122ºF]
Max ± 5ºC
0.1ºC [0.2ºF]
This option appears if you’ve set one of the analog inputs to EtS (External temperature sensor). When the thermostat is
connected to the appropriate analog input, the display shows the temperature read by the external temperature sensor. Adjust
the offset by comparing it with a known value (e.g. thermometer). If the sensor is not connected or short circuited, then the unit
displays the sensor's limit.
3. “Prs”(input 3 reading)
Range:
250mV (0") to 4000mV (1")
Displays the voltage output value in mV of the pressure sensor. Does not appear for EVCB14NDT4S and EVCB14NDT4X
(pressure dependant) models.
4. “PRS MIN" (input 3 minimum reading)
Range:
Default:
10mV to 180mV
60mV
This setting represents the deadband of the pressure sensor in mV. For advanced users or special applications only. We
recommend that you use the default setting of 60mV. Does not appear for EVCB14NDT4S and EVCB14NDT4X (pressure
dependant) models.

1. During the power up sequence of the thermostat (when the firmware versions are displayed), press and hold both the and
buttons.
2. The “PAS”screen appears. Enter 372 within 1 minute by using the arrow keys to increase or decrease the value and the
and buttons to toggle between the digits.
3. Use the arrow buttons to select YES and then press .
Operation Mode
The Mode Selector Jumper (JP1) of the thermostat must be set to the “RUN” position (Operation Mode). Refer to Wiring on
page 5.
Power Up
Upon power up, the LCD illuminates and all segments appear for 2 seconds. The thermostat then displays its current version of the
thermostat for 2 seconds followed by the current version of the controller for 2 seconds. Pressing any key on the thermostat
illuminates the LCD for 4 seconds.

Temperature
The thermostat displays the temperature reading for 8 seconds. If the sensor is disconnected or short circuited, then the unit
displays the sensor's limits. To toggle the temperature scale between ºC and ºF, press the button.
Temperature Setpoint
To display the setpoint, press the or key twice. The set point appears for 5 seconds. To adjust the setpoint, press the arrow
keys while the temperature is displayed. If the setpoint adjustment has been locked, the lock symbol appears.
Air Flow and Air Supply Temperature
Press and hold the button for 5 seconds and use the arrow keys to view the:
“Flo”(airflow)
“FOS" (airflow setpoint)
“dPR" (actual damper position percent)
“aST (air supply temperature).
After 5 seconds without any action, the thermostat returns to operation mode. The air supply temperature appears only if analog
input AI1 or AI2 are configured with the AST option. The airflow and airflow setpoint only appear when in pressure independent
mode. The actual damper position percent only appear with the following standard models: EVCB14NIT0S, EVCB14NIT2S,
EVCB14NIT4S, EVCB14NDT4S, EVCB14NIT0SF, and EVCB14NIT4SF
Control Mode
To access the Control Mode, press the button. The Control Mode appears for 5 seconds. Press the button to scroll
through the following control modes. These options can vary depending on the options selected in "Temp Control Mode" and
"Enable OnOff Control Mode".
•Auto (Automatic Cooling or Heating)
•Cooling only (on, with cooling symbol)
•Heating only (on, with heating symbol)
•OFF (if it is not disabled in Programming Mode)
Night Set Back (NSB) or Occupancy Mode
This function is only available if you set DI1 to nSb (Night set back contact) or Occ (occupancy mode). If the DI1 contact is
triggered, the thermostat enters NSB or No Occupancy Mode (the symbol appears) and uses the NSB or OCC heating and
cooling setpoints.
If not locked, you can override the night set back or no occupancy mode for a predetermined period by pressing any of the 4
buttons. During the override period the symbol will flash. If the symbol does not flash, the override period is finished or the night
set back or no occupancy override has been locked in programming mode.
Set Time and Date
1. Ensure that JP1 on the thermostat is set to run.
2. Press and hold the button for 5 seconds
3. Use the arrow keys to set the desired value. Press the button to save and got to the next step. Press the button to
go to the previous step without saving.
