PIR Ready VTR7300 Series

Terminal Equipment Controllers

For Commercial and Lodging HVAC Fan Coil Applications

(Issue Date: March 29, 2010 – 028-0298_R0)

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 Transformer 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 Transformer 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 = 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.
