I NSTALLATION
IMPORTANT: ALL WIRING MUST CONFORM TO LOCAL
AND NATIONAL ELECTRICAL CODE REGULATIONS.
Please read the following instructions carefully before proceeding with the
installation. Failure to follow the instructions could damage the product or
cause a hazardous condition. Installation must be performed by a qualified
service technician or electrician. Disconnect power supply before installing in
order to prevent electrical shock.
There are three basic methods for installing the VC3000 transformer relay pack controller.
A) Inside an electrical cabinet of a fan coil unit
• Use the plastic mounting tabs to secure the unit to the inside of the electrical enclosure.
• Secure to the inside with screws.
• Cut one or both plastic mounting tabs if space is needed inside the enclosure.
• Install a low voltage or high voltage metal separator if required.
• Do not exceed the maximum rated temperature of the unit. (50 °C/122 °F)
2 VC7300 Series-Installation Guide
B) Outside of a junction box or electrical cabinet
• Use the supplied lock nut to secure the transformer relay pack to the electrical junction
box or to the electrical cabinet of the fan coil unit.
C) Enclosed low voltage junction box type installation (if required by local codes)
• Install the transformer relay pack inside a 4”x 4” junction box.
• Cut one or both plastic mounting tabs if space is needed inside the enclosure.
• Use the supplied lock nut to secure the transformer relay pack (inside its junction box) to
the main electrical junction box or to the electrical cabinet of the fan coil unit.


If replacing an old line voltage fan coil controller, label the wires
before removal of the old controller.
Electronic controls are static sensitive devices. Discharge yourself
of any electrostatic build-up before manipulating or installing the
terminal equipment controller.

A short circuit or wrong wiring may permanently damage the
terminal equipment controller or the equipment.

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.

COMMUNICATION WIRING TO VTR73 XX A
TERMINAL E QUIPMENT CONTROLLER
Only one VC3xxxX relay pack with remote monitoring inputs can be used under a single
VTR73xxA controller. All other slave units must be either VC3xxxX relay pack(s)
WITHOUT remote inputs. A maximum of 10 VC3xxxX relay packs can be used for a
single VTR73xxA terminal equipment controller.
From the VTR73xxA to the first VC3xxxX
o Existing or new field wires
o 3 minimum required 14-22 Ga solid or stranded. Shield not necessary.7
From the first VC3xxxX to the controller to all other VC3xxxX Relay Pack(s)
o Existing or new field wires
o 2 minimum required 14-22 Ga solid or stranded. Shield not necessary.
o Connect only common and 2 Tx / Rx communication

Possible network wiring topology
The VTR7300 to VC3000 transformer relay pack can use any network wiring topology as
required or based on topology of existing wires.
