The document discusses EVC, EFC, and BACnet controllers. The EVC series is a VAV box controller combined with an actuator and thermostat. It is available for pressure dependent or independent systems and with BACnet communication. The EFC series consists of a fan coil controller and thermostat. It is available in various voltages with BACnet and supports sensors, outputs, and fan speeds. The document provides details on the functionality and connections of the thermostats and controllers.

19. •We are active Member of BACnet® International
•All Neptronic BACnet® products are certified to BTL
(BACnet® Testing Laboratories)
•We are BACnet® MS/TP over RS-485
2 wire cable, twisted-shielded (BACnet IP Summer 2012)
•Baud rate can be set to one of the following: 9600, 19200,
38400 or 76800 bps

20. • Baud Rate
– One device at a different baud rate than the controller or other
devices will crash the trunk
• MAC Address
– Lots of time people will forget to change the factory default
MAC to a unique address on their network (set at 0 by default)
• T-taps
– Too many T-taps will result in communication issues (max 65‘
per T-tap,130‘ total max)

22. Neptronics Major BACnet Characteristics ASC
1. Two MAC addressing options
-Controller and/or Thermostat
2. Auto Device Instance Configuration
3. Auto baud rate
4. Copy configuration
5. Service Display Address
(Service Display Address) EVC EFC

23. 1. Two MAC addressing options
1-DIP switch Mac addressing is 2- Thermostat
always priority vs Thermostat

24. 2- Auto Device Instance Configuration
All NEPTRONIC Controllers come with a
default Device Instance (D.I.) value of
153 000
(153 is NEPTRONIC’s BACnet vendor ID
number)
To which a MAC address is automatically
added to

25. 2- Auto device instance configuration
As you set the MAC address, the Instance
automatically set the Device Instance (D.I.)
MAC Address: 21
Default Device
Instance (D.I.): 153000
Automatic D.I. 153021

26. 3- Auto baud rate
Controller « Listens » & identifies the
networks baud rate and sets its speed
accordingly (9,6/19,2/38,4/76,8Kb)
MS/TP Network @ « X Kb » Speed

27. 4- Copy configuration:
A Single profile or application can be
pushed to similar Zone Controllers

28. 4- Copy configuration:
Copies configuration VAV2
VAV3
VAV 1 Profile type: VAV 4
1 Changeover Remote Sensor input
1 Reheat on/off Output HW Valve VAV5
1 Reheat TPM Output (Duct heater)
VAV6

29. 4- Copy configuration:
Avantage:
Push globally and not pull
individually to similar
information to identical
controllers.

30. 5- Service Display Address:
Helps you identify a specific controller on a
given network

31. Neptronic’s BACnet® Controls
Advantages:
• Cuts labor costs
• Increases your productivity
• Flexibility that fits your needs

34. • Design to mount on most spring loaded
valves
• Delivers a minimum of 200N force
• Modulating analog or digital control
signal, Failsafe up or down
• Easy installation (no tools)

35. • 10 Inputs and 10 Outputs (8UI-2AI/6DO-4AO)
• 1 BACnet MS/TP and 1 MODbus Ports
• Possibility to add 8 slave Tstats
• Optional : LCD Display, RTC
