Description
The EFCB Series Networkable Fan Coil Controller and TFL
Series LCD Thermostat are designed for simple and
accurate control of any fan coil application. The Networkable
Fan Coil Controller is mounted inside the fan coil cabinet and
incorporates a configurable fan coil algorithm, variable three
speed fan control and either modulating or digital heating
and cooling outputs. All inputs and high/low voltage outputs
are centralized at the control module in the fan coil cabinet.
Applications
 Compatible with 2 or 4 pipe systems
 Fan coil unit (up to 3 speeds and/or analog 0-10 Vdc)
 Cooling signal (on/off, floating or modulating 0-10 Vdc)
 Heating signal (on/off, floating, pulse or modulating 0-10 Vdc)
 Cool, Heat, Reheat, Reheat with fan, Changeover, Fan,
Humidify and Dehumidify by cooling.
Typical Application
Features
 Built-in configurable fan coil algorithms
 Up to 10 inputs and 15 outputs (configurable)
 Select direction on digital inputs and all outputs

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 (DS2)
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.
MAC Address DS.1 = 1 DS.2 = 2 DS.3 = 4 DS.4 = 8 DS.5 = 16 DS.6 = 32 DS.7 = 64 DS.8 = 128 Default Device Instance

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 Mode
The Mode Selector Jumper of the thermostat must be set to the “RUN” position (Operation Mode). Refer to Wiring on page 4.
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 Display and Setpoint
The thermostat displays the temperature reading. If the sensor is disconnected or short circuited, the unit displays the sensor's
limits. To toggle the temperature scale between ºC and ºF, press both the and keys for 3 seconds. To display the setpoint,
press the and 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.
Temperature and Humidity (TFLH54 thermostats only)
The thermostat displays the temperature reading for 8 seconds and then displays the humidity reading for 2 seconds. If the sensor
is disconnected or short circuited, the unit displays the sensor's limits. To toggle the temperature scale between ºC and ºF, press
both the and keys for 3 seconds.
To access the Humidity setpoint, press the button for 5 seconds. The humidity setpoint will be displayed for 5 seconds. To
adjust the setpoint, press the and keys while the setpoint is displayed. The unit will return to normal mode if you do not press
any key for 3 seconds. The changed values will be saved automatically.
Control Mode
To access the Control Mode, press the key. The Control Mode appears for 5 seconds. Press the key to scroll through
the following control modes. These options can vary depending on the options selected.
 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)
Fan Speed Selection Mode
To access the Fan Speed selection mode, press the key. The mode appears for 5 seconds. These options can vary
depending on the fan speed signal and auto mode settings. If in No Occupancy mode, the button now serves as the override
button.
 Automatic speed. Available only if enabled in program mode.
 Low speed
 Medium speed
 High speed
 Off. Off is not selectable by the user, it appears only if the "Control Mode" is "Off" and it indicates that the user can not change
the speed of the fan.
Night Setback (NSB)
This function is only available if you’ve set DI3 to nSb (Night setback contact) If the DI3 contact is triggered, the thermostat enters
NSB Mode (the symbol appears) and uses the NSB setpoints defined in program mode. Press any key to override NSB for the
delay defined in program mode (default: 120 minutes). The symbol flashes to indicate that the NSB mode is overridden (during
this time the standard set points are used).
If the NSB Mode was set to OFF, all outputs will be off for the duration of the period and cannot be overridden.
Occupancy Mode
This function is only available if you’ve set DI3 to Occ (occupancy mode). If the DI3 contact is triggered, the thermostat enters
Occupancy Mode (the symbol appears) and uses the NoOcc setpoints defined in program mode.
If not locked, no occupancy mode can be overridden for a period by pressing the button. Each time you press the button,
15 minutes are added to the override (up to a maximum defined in program mode). Press the fan button until “0” is displayed
to disable the override. The icon will flash and the remaining override time will be displayed in minutes.
