responsibility for errors or omissions Technical Guide The Right WattMaster VAV System WattMaster VAV series of controllers and components are con together with communication wiring to form complete systems WattMaster VAV controllers can be configured into two main types which are the Networked Single Loop or the Networked Loop system The right system for you depends on the number types of controllers being used Each of these main system types a series of options available that relate to what kind of operators you wish to use to program and monitor your WattMaster system Several other options are available depending on the sys type and operators interface you have selected By selecting the system and options you can build a complete HVAC controls sys that will meet your job requirements the Selection Chart has designed this publication in order to make it easy to the right WattMaster VAV system type for your specific applica Start by selecting a main system type from the selection chart be Proceed to the pages listed on the selection chart for information available options for that system type After deciding what opera interface and other options you want proceed to the connections section pages listed for that system type for detailed installation WattMaster VAV System I Select You Have A Single Unit With Controllers Number of All Combined Exceed 59 You Have Between 1 to 59 HVAC Unit or Add On Controllers One Unit That has Controllers Number of All Combined Exceed 59 The Networked Loop System Pages 4 5 6 The Networked Loop System Pages 4 5 6 You Have More Than HVAC Unit Or Add On And Or HVAC Units VAVBOX The Networked Loop System Pages 7 8 9 Technical Guide Single Loop System Networked Single Loop system is used when you have between 1 59 WMVAV controllers VAVBOX controllers and Add on Device total Only one of the WMVAV controllers on the loop may have VAVBOX controllers attached If your system exceeds any of limitations you will need a Networked Multiple Loop System your proposed system has WMVAV and or Add on Device con with only 1 WMVAVcontroller that has VAVBOX controllers the total number of these controllers and Add on Devices is 59 or you should use the Networked Single Loop System If you have than 1 WMVAV with VAVBOX controllers or more than 59 total and Add on Devices please see the Networked Multiple Loop that follows To create this system simply connect the control together in a daisy chain fashion using WattMaster communica wire or 18 gauge 2 conductor twisted pair with shield wire Belden or equivalent These are then connected to the system com devices All WattMaster VAV systems require that a II and a MiniLink Polling Device system communication are purchased and wired into the communications loop The CommLink and MiniLink Polling Device are available as a by ordering the OE715 VAV WMVAV System Package Program and status monitoring are accomplished by selecting and install an operators interface For most controllers any one of the opera interfaces can be used for system programming and monitoring or or all three can be used together if desired The exception to this is any Add on Devices are used The Add on Devices must be pro with a PC using the WattMaster VAV Prism software they be programmed with the System Manager or the Modular Ser Tool See the section titled Interface Options that fol for a list and block connection diagrams of the operators interface available along with their capabilities and limitations For de wiring and connection diagrams of the Networked Single Loop see pages 10 11 and 12 Interface Options Service Tool Modular Service Tool provides complete programming and moni capabilities for WMVAV and VAVBOX controllers Add on De controllers cannot be programmed with the Modular Service Tool Modular Service Tool connects to the controller by means of a cable with DIN connectors It is normally used to program and the unit and then is removed by the service person upon comple of these tasks The Service Tool is not designed for permanent in Generally the service person would only connect it when ser or reprogramming the controller For this reason if continuous of the controllers is required it is better to select a System or an on site PC for programming and monitoring The Ser Tool can be used in conjunction with the other operators interfaces desired Manager System Manager provides programming and monitoring of con in a package that is designed for permanent wall mounting in space or an equipment room It is housed in an off white plastic that is suitable for most decors The System Manager is also with alarm and override LED indicators on its faceplate Add Device controllers cannot be programmed with a System Manager Computer With Prism Software computer interface can also be used in conjunction with the other interfaces listed above or by itself The PC used can be a or desktop computer WattMaster VAV Prism software must be on the PC WattMaster VAV Prism Software is available free charge at our website www wattmaster com If remote connection a phone line is required you must also purchase and install a Remote For remote computer connection via an intranet or Internet you purchase and install the IP Link instead of the Remote Link an on site and remote PC can be used together if desired personal computer to be used with the Orion Prism software must or exceed the following specifications Compatible Computer 200 MHz or Faster Microprocessor Meg RAM 95 98 ME XP 2000 NT VGA Monitor w 1024 x 768 Resolution Minimum
