Selecting The Right WattMaster VAV System
Technical Guide
The WattMaster VAV series of controllers and components are connected together with communication wiring to form complete systems
solutions. W attMaster VA V controllers can be configured into two main
system types, which are the Networked Single Loop or the Networked
Multiple Loop system. The right system for you depends on the number
and types of controllers being used. Each of these main system types
have a series of options available that relate to what kind of operators
interface(s) you wish to use to program and monitor your WattMaster
VAV system. Several other options are available depending on the system type and operators interface you have selected. By selecting the
right system and options you can build a complete HVAC controls system that will meet your job requirements.

Using the Selection Chart
WattMaster has designed this publication in order to make it easy to
select the right WattMaster VAV system type for your specific application. Start by selecting a main system type from the selection chart below. Proceed to the pages listed on the selection chart for information
and available options for that system type. After deciding what operators interface and other options you want, proceed to the connections &
wiring section pages listed for that system type for detailed installation
information.

Technical Guide
Networked Single Loop System
The Networked Single Loop system is used when you have between 1
to 59 WMVAV controllers, VAVBOX controllers and Add-on Device
controllers total. Only one of the WMVAV controllers on the loop may
also have VAVBOX controllers attached. If your system exceeds any of
these limitations you will need a Networked Multiple Loop System.
When your proposed system has WMVAV and/ or Add-on Device controllers with only 1 WMVAVcontroller that has VAVBOX controllers
and the total number of these controllers and Add-on Devices is 59 or
less, you should use the Networked Single Loop System. If you have
more than 1 WMVAV with VAVBOX controllers or more than 59 total
controllers and Add-on Devices, please see the Networked Multiple Loop
section that follows. To create this system simply connect the controllers together in a daisy chain fashion using WattMaster communications wire or 18 gauge 2 conductor twisted pair with shield wire (Belden
#82760 or equivalent). These are then connected to the system communication devices. All WattMaster VAV systems require that a
CommLink II and a MiniLink Polling Device system communication
device are purchased and wired into the communications loop. The
required CommLink and MiniLink Polling Device are available as a
kit by ordering the OE715-VAV WMVAV System Package. Programming and status monitoring are accomplished by selecting and installing an operators interface. For most controllers, any one of the operators interfaces can be used for system programming and monitoring or
two or all three can be used together if desired. The exception to this is
when any Add-on Devices are used. The Add-on Devices must be programmed with a PC using the WattMaster VAV Prism software, they
cannot be programmed with the System Manager or the Modular Service T ool. See the section titled “Operators Interface Options” that follows for a list and block connection diagrams of the operators interface
options available along with their capabilities and limitations. For detailed wiring and connection diagrams of the Networked Single Loop
systems see pages 10, 11 and 12.
Operators Interface Options
Modular Service Tool
The Modular Service T ool provides complete programming and monitoring capabilities for WMVAV and VAVBOX controllers. Add-on Device controllers cannot be programmed with the Modular Service T ool.
The Modular Service Tool connects to the controller by means of a
modular cable with DIN connectors. It is normally used to program and
service the unit and then is removed by the service person upon completion of these tasks. The Service Tool is not designed for permanent installation. Generally the service person would only connect it when servicing or reprogramming the controller. For this reason if continuous
monitoring of the controllers is required, it is better to select a System
Manager or an on site PC for programming and monitoring. The Service T ool can be used in conjunction with the other operators interfaces
if desired.
System Manager
The System Manager provides programming and monitoring of controllers in a package that is designed for permanent wall mounting in
the space or an equipment room. It is housed in an off white plastic
housing that is suitable for most decors. The System Manager is also
provided with alarm and override LED indicators on its faceplate. Addon Device controllers cannot be programmed with a System Manager.
.
Personal Computer With Prism Software
A computer interface can also be used in conjunction with the other
operators interfaces listed above, or by itself. The PC used can be a
laptop or desktop computer. WattMaster VAV Prism software must be
installed on the PC. WattMaster VAV Prism Software is available free
of charge at our website, www.wattmaster.com. If remote connection
via a phone line is required you must also purchase and install a Remote
Link. For remote computer connection via an intranet or Internet you
would purchase and install the IP-Link instead of the Remote Link.
Both an on-site and remote PC can be used together if desired.
The personal computer to be used with the Orion Prism software must
meet or exceed the following specifications:
• IBM™ Compatible Computer
• Pentium 200 MHz or Faster Microprocessor
• 64 Meg RAM
• Windows 95 / 98 / ME / XP / 2000/ NT
• Super VGA Monitor w/ 1024 x 768 Resolution Minimum
• Available Serial Port for On Site Installations
• Internal or External Modem for Remote Installations
• Network Card for TCP/IP Communications
A PC with Prism installed provides features not available with the other
operators interfaces:
• Trend logs can be exported for easy use into any standard
spreadsheet/database program
• Automatic installation
• Alarm logs are maintained on disk
• E-mailing of alarms
• History logs of user interactions with the system
• On site or remote modem or TCP/IP communications
• User programmable descriptions for every piece of
equipment
• User definable passcode levels for setpoints
• Current status printouts
• User defined custom screens for floor plans, etc.
• Tenant log creation for tenant override Billing
• Automatic retrieval of trend logs
Communication Device Options
All Networked Single Loop system require that you have both a
CommLink and MiniLink PD installed on the system for correct operation. Other optional communication devices are listed in the following
paragraphs along with a description of how they function with the Networked Single Loop control system.

Technical Guide
Remote Link
The Remote Link is used with the CommLink to provide for a remote
PC to interface to the system via a phone line. It can also be used with
the CommLink to provide alarm callouts to a pager without requiring
an on site or remote PC.
IP-Link
The IP-Link is used with the CommLink to provide for a remote PC to
interface to the system via a local intranet or the Internet. The IP-Link
will allow up to 5 computer TCP/IP connections to be operating at the
same time.

Add-on Device Requirements
If you wish to use any of the Add-on Device controllers on your system
you must use a PC with the Prism software installed for programming
and monitoring of the controllers. These devices cannot be programmed
or monitored from the System Manager or Service Tool.
The Add-on Controllers that require a PC for programming and monitoring are:
• GPC and GPC-17
• Lighting Controller
