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.

TDF10 / TDF40 / TDF70 Series

CAUTION: Remove power to avoid a risk of malfunction.

A. Remove the wall mounting plate (highlighted) from the back of the digital room sensor.

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 digital room sensor onto the wall plate. To mount it correctly, place the top of the digital room sensor on the

mounting plate first and push it into the grooves to snap it into place.

E. Secure the digital room sensor using the screw (supplied).

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.

For 120/240Vac models, it is recommended to have separate power sources for the EFCB controller and the Fan Coil Unit, in order

to protect the device circuitry from any surge in power supply.
