Description
The EFCB-OE1 Series Networkable Fan Coil Controller,
and TFL24 and TDU Series LCD Thermostats 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.

CAUTION: Remove power to avoid a risk of malfunction.
A. Remove the wall mounting plate (highlighted) from the back of the thermostat.
B. Install the mounting plate on the gang box.
C. Pull the wires through the base hole and make the appropriate connections.
D. Mount the thermostat onto the wall plate. To mount the thermostat correctly, place the top of the thermostat on the mounting
plate first and push it into the grooves to snap it into place.
E. Secure the thermostat using the screw (supplied).
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.

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.
