VC3XXXX Series Line Voltage Switching Relay Packs
For Commercial and Lodging HVAC Fan Coil Applications
(Issue Date: March 29, 2010 – 028-6021_R00)
Product overview
The VTR73XX Series Fan Coil Terminal Equipment Controller used in conjunction with the
VC3000 Series Line Voltage Switching Relay Packs is specifically designed for fan coil
control applications. They can be used both for new or retrofit applications. In retrofit
applications, they can re-use the existing wires between the old line voltage switching
thermostat and the fan coil thus saving on the installation of any new wires. Stand-alone
and network operation are available.
The VTR73XX Series Fan Coil Terminal Equipment Controller features a backlit LCD
display with dedicated function menu buttons for simple operation. Accurate temperature
control is achieved due to the product’s PI proportional control algorithm, which virtually
eliminates temperature offset associated with traditional, differential-based Terminal
Equipment Controllers. All models feature configurable System and Fan button functions to
meet all possible applications The VTR73XX Terminal Equipment Controllers are powered
and communicate with the associated VC3000 Series Relay Pack(s) using only 3 wires.
2 types of interfaces for the user can be ordered. The VC73x5 models are typically used for hotel and lodging applications
where the middle button of the interface is for the user to select the local displayed scale in ºF or ºC. The VC73x0 models are
typically used for commercial and institution applications where the middle button of the interface is defined for the local
unoccupied override function.
The VTR73XX Terminal Equipment Controllers are also compatible with the new Viconics PIR
cover accessories. Terminal Equipment Controllers equipped with a PIR cover provide
advanced active occupancy logic, which will automatically switch occupancy levels from
Occupied to Stand-By and Unoccupied as required by local activity being present or not. This
advanced occupancy functionality provides advantageous energy savings during occupied
hours without sacrificing occupant comfort. All Terminal Equipment Controllers can be
ordered with or without a factory installed PIR cover ( see ordering notes below ).
The compatible VC3000 Series Line Voltage Switching Relay Pack(s) operate as slave unit(s)
under the control of a single master VTR73XX Terminal Equipment Controller. A single
VTR73XX Terminal Equipment Controller can control up to 10 VC3000 Series Relay Pack. The
VC3000 Series Relay Packs are line-powered units. They locally contain all the relay outputs for fan switching and valve control.
Models are also available for extra monitoring / control inputs of the Fan Coil Units.

Ordering Information Notes:
The (X) at the end of the model number represents available communication options:
•
X = none for Stand-alone
• X = E for Echelon
•
X = B for BACnet MS-TP
• X = W for Wireless
The Terminal Equipment Controllers can be ordered with a factory installed PIR cover. Please use (5500) extension instead of
the (5000) only extension. The Terminal Equipment Controllers ordered without a PIR cover can be retrofitted with a separate
PIR accessory cover afterwards if required.
Ordering examples:
• A VTR7305AW5500B is for a wall mounted Terminal Equipment Controller with a hotel / lodging interface with a factory
mounted PIR cover and an MS-TP BACnet communication interface.
• A VTR7350A5000W is for a wall mounted Terminal Equipment Controller with a commercial / institution interface and a
wireless communication interface. The Terminal Equipment Controller can be retrofitted with a separate PIR accessory
cover afterwards if required.
