VT7200X Series Product Overview

The VT7200 PI thermostat family is specifically designed for zoning applications. Typical applications include local hydronic reheat valve control and pressure dependent VAV with or without local reheat. The product features a backlit LCD display with dedicated function menu keys 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 thermostats. Models are available for 3 point floating and analog 0 to 10 Vdc control. In addition remote room sensing is available.

They all contain an SPST auxiliary switch that can be used to control lighting or auxiliary reheat. 3 additional inputs are also provided for monitoring and / or various advanced functions.

VT73xxX Series Product Overview

The VT7300 PI thermostat family is specifically designed for fan coil control. The product 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 thermostats.

Models are available for On/Off, 3 point floating and analog 0 to 10 Vdc control and can control up to three fan speeds. Three additional inputs are also provided for monitoring and / or various advanced functions.

All models feature configurable System and Fan button functions to meet all possible applications. They all contain an SPST auxiliary switch that can be used to control lighting or auxiliary reheat.

All devices are also available with Echelon, BACnet MS-TP or Zigbee wireless network adapter. The thermostats are also compatible with the new Vykon PIR cover accessories. Thermostats 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 thermostats can be ordered with or without a factory installed PIR cover.

For clarity we will use the term “Device” to represent any product with an active Echelon network connection, including Vykon and non-Vykon controllers.

Summary Specifications:

One RC network with Ra = 52.3Ω±1%, 1/8W Two RC network with Ra = 105Ω±1%, 1/8W

Segment Number of transceivers per segment Up to 64 Baud rate 78000 bits per second

Network segment length varies depending on wire type.

Table 1: Summary of Specifications for a Vykon’ LON Network

Network Configuration

The Echelon network is designed to support free topology wiring and will accommodate bus, star, loop or any of these topologies. Echelon devices can be located at any point along the network wiring.

Figures 3.1 to 3.5 present five different network topologies. The actual termination circuit will vary by application.

Maximum Number Of Devices

Up to 64 transceivers are allowed per network segment. If your network requires more than 64 transceivers a repeater is then required to extend your network

Maximum Cable Length

The maximum length of a chain is related to its transmission speed. The longer the chain, the slower the speed. Using proper cable, Echelon supports a baud rate of 78 kilobits per second for distances up to 1600ft (500 m) in free topology and 8800 ft (2700 m) in bus topology with double terminations.

If you require a maximum network length of more than 1600-ft (500 m) or 8800 ft (2700 m), then a repeater is required to extend the network.

Repeater

In the event that the limits on the number of transceivers or total wire distance are exceeded, a physical layer repeater can be added to interconnect two or more network segments. A repeater will double the overall channel capability, including node count and network extent, but not bandwidth. Note that only one physical layer repeater should be placed in series between any two nodes on a channel. If additional cabling or network bandwidth is required, then a LonWorks Router should be used in place of a repeater.

Terminators

Echelon network segments requires termination for proper data transmission performance. The type of terminator varies depending on whether shielded or unshielded cable is used. Free topology and Bus networks also differ in their termination requirements. The following sections describe the various terminators and terminations procedure.

Free Topology Network Segment

In a free topology segment, only one termination is required and may be placed anywhere on the free topology segment. There are two choices for the termination:

1. RC network with Ra = 52Ω±1%, 1/8W

2. LPI-10 Link Power Interface, with jumper at “1 CPLR” setting.

Doubly Terminated Network Segment

In a doubly terminated bus topology, two terminations are required, one at each en of the bus. There are two choices for each termination:

1. RC network with Ra = 105Ω±1%, 1/8W

2. LPI-10 Link Power Interface, with jumper at “2 CPLR” setting.

Only one LPI-10 interface is supported per segment. The other terminator must be an RC-type.

Grounding Shielded Twisted Pair Cable

When using Shielded Twisted Pair, terminate the twisted pair as listed in the previous section and ground the cable shield by using a capacitor, to tie the shield to earth ground, and a large-value resistor to bleed off any static charge on the shield. Tying the shield to earth ground through a capacitor will avoid DC and 50/60Hz ground paths from being formed through the shield. Typical values for resistor and capacitor are as follows:

Capacitor = 0.1μF, 10%, Metalized Polyester, ≥ 100V Resistor = 470kΩ, 1/4W, ±5%

The cable shield should be grounded at least once per segment, and preferably at each node. Grounding the shield at every node will assist in suppressing 50/60Hz standing waves.

Network adapter

Although network connections are polarity insensitive, it is good practice to keep polarity consistent throughout the entire site. Figure 4 shows a network connection example and the location of the Status LED. This Status LED may help to troubleshoot network problems.

Figure 4: Network connections and location of the Status LED on a LON module

Table 2 shows the different possibilities with the Status LED behaviour of the LON module.

Condition of the Status LED Explanation

¾ Continuously ON The device has no application loaded in its memory and is

Un-configured

¾ Flashing at a rate of 1/2Hz The device has an application loaded in its memory but is

Un-configured. When a device is in the un-configured state, it does not know which devices to communicate with. A network management tool is used to logically bind the node to another in a LonWorks network.

¾ Continuously OFF The device has an application loaded into its memory and is

bound onto a LonWorks network.

Table 2: Status LED condition

Software Files XIF: When binding a node onto the network, an XIF file is needed. The XIF file has information that is used by

the network management tool to help ease the installation and maintenance process of a node. It is also used for offline configuration of the node.

APB and NXE: When running an application program associated with a XIF file, an APB or NXE file is needed. Please note that the thermostats have the APB file already flashed from the factory.

Device Resource File (DRF): When a LON network management tool is used; a DRF file must be installed. DRF files are needed to display special manufacturer defined variables or configurations correctly.

• Please note that all release notes for the XIF, APB & NXE software files will be included under the

following folder name on your hard drive: C:\LonWorks\Import\Vykon. The name of the file is: VT7xxxReadme.txt

Plug-Ins File: LNS Plug-Ins simplify start-up, maintenance, configuration and reduce the installation effort.

• Please note that all release notes for Plug-Ins files will be included under the following folder

name on your hard drive: C:\LonWorks\Plug-Ins\Vykon\VT7xxx. The name of the file is: Readme.txt.
