Special Precautions

Replacing Old Fan Coil Controller
If replacing an old line voltage fan coil controller, label the wires before removal of the old controller.

Electrostatic Discharge
Electronic controls are static sensitive devices. Discharge yourself of any electrostatic build-up before
manipulating or installing the terminal equipment controller.

Short-Circuits
A short circuit or wrong wiring may permanently damage the terminal equipment controller or the equipment.

Proper Installation and Use
VC3000 series transformer relay packs are to be used only as operating controls. If installed incorrectly the
intended application may fail or lead to personal injury or loss of property. It is the responsibility of the end
user to ensure that the device has been properly installed by a certified professional and that proper safety
precautions have been taken to protect against failures.
