PIR Application Guide for the for VT7xxxX5000(X) Series thermostats

( Issue Date: November 5, 2007 – 028-xxxx Rx )

Product Overview

The VI-PIR Accessory covers with embedded Passive Infra-Red motion detector have been

specifically designed to work with all compatible VT7000 series thermostats. Thermostats

compatible with VI-PIR covers use the following part number assignments: VT7xxxxX5xxx(X). The

5 identifies the thermostat base thermostat has the necessary onboard polarized PIR connector

and functionality added.

When equipped with a VI-PIR accessory cover or a remote PIR sensor attached to one of the

remote input, a VT7000 series thermostat provides advanced active occupancy logic, which will

automatically switches 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.

The range of applications covered with the PIR occupancy logic van be segmented in 2 important categories in terms of

functionality. Both use different settings and have different behaviours:

• Hotel and lodging applications

• Standard commercial applications

Typical applications that can be meet by the new PIR accessory covers range from:

• Stand-alone lodging FCU applications

• Networks lodging FCU applications fully integrated to a reservation system

• Networked or stand-alone conference rooms

• Networked or stand-alone classrooms units

• Any commercial offices that have random occupancy schedules during occupied hours as dictated by the

function of the tenant

• Or any controlled piece of HVAC equipment that may yield energy savings with the introduction of a new

automatic stand-by level of occupancy.

PIR Application Guide for the for VT7xxxX5000(X) Series thermostats ( Issue Date: November 5, 2007 – 028-xxxx Rx ) Product Overview The VI-PIR Accessory covers with embedded Passive Infra-Red motion detector have been specifically designed to work with all compatible VT7000 series thermostats. Thermostats compatible with VI-PIR covers use the following part number assignments: VT7xxxxX5xxx(X).

Configuration Parameters Associated with the Viconics PIR Accessory Covers The following configuration parameters are specifically provided as standard on all VT7000 series thermostats. They are associated with the advanced occupancy functionality introduced with the addition of a PIR cover or a remote PIR sensor. These parameters will allow the installer to set the thermostat occupancy functions exactly as required by the application.
PAGE 3
Important Notes and Things to Know When reviewing the following document and planning an application using a Viconics thermostat with PIR functionality, please remember the important following notes: • Configuration of PIR Functions: All PIR application related configuration parameters are displayed in the configuration menu or available as objects in the network object list.
PAGE 4
• Unoccupied Timer Disable: In certain application cases, it may be desired to never let the local area enter the unoccupied mode and always stay at the stand-by occupancy level when no activity is present. 4 This allows for advanced flexibility when used in conjunction with a network or in cases when areas always need to be on stand-by status ready to respond to demand at any point in time.
PAGE 5
Network Occupancy Feedback Status: All VT700 series thermostats have 4 occupancy feedback levels. This is valid for all network variations available for the thermostats: LON, BACnet-MS-TP or Wireless.
PAGE 6
• Initial State, PIR Occupancy Routine: The initial effective occupancy state on power-up with either a PIR cover is 6 present or one of the inputs is configured for a remote PIR sensor is always Stand-By mode. When the network effectively releases a thermostat to its local PIR routine from a previous occupied or unoccupied network state, the resulting occupancy state is always Stand-By mode.
