Application Note
Document Introduction
This document describes a number of possible application scenarios using the
TEC2x45-4, TEC2xx6(H)-4, TEC2xx6H-4+PIR, TEC2xx7-4, and TEC26x7+PIR
Series Thermostat Controllers. Each application scenario includes a table that lists
the setup and configuration parameters required for that specific application. Refer
to the appropriate thermostat controller installation instructions for more
information on adjusting the configuration parameters.
For those application scenarios that include a door switch, a Normally Closed
(N.C.) door switch is required. With a N.C. door switch, the contact is closed only
when the door is closed. In these application scenarios, the term door toggle means
the door is initially closed, then opened, and closed again.
Key Concepts
Passive Infrared (PIR) Occupancy Sensing Cover
PIR motion detecting technology is available as an embedded sensor onboard TEC
Thermostat Controller accessory covers. The optional PIR accessory covers are
specifically designed to provide an occupancy sensing capability with compatible
TEC2x45-4, TEC2xx6(H)-4, TEC2xx6H-4+PIR, TEC2xx7-4, and
TEC26x7-4+PIR Series Thermostat Controllers.
When equipped with a PIR accessory cover, the thermostat controller provides
advanced active occupancy logic, which automatically switches occupancy levels
from Occupied to Unoccupied or Standby as required by the presence of local
activity. This added occupancy sensing capability provides energy savings during
occupied hours without sacrificing occupant comfort.
A PIR accessory cover is suited for the following applications:
• Hospitality Fan Coil Unit (FCU) applications
• TEC Zoning System Zones
• Conference rooms
• Classroom units
• Any commercial offices that have random occupancy schedules during
occupied hours as dictated by the function of the tenant
• Any controlled piece of Heating, Ventilating, and Air Conditioning (HVAC)
equipment that may yield energy savings with the introduction of a new
automatic standby level of occupancy

technical specifications, refer to the PIR Accessory Cover Installation Instructions
(Part No. 24-9890-870).
PIR Accessory Cover Configuration Parameters
The following configuration parameters are specifically provided as standard on
all TEC2x45-4, TEC2xx6(H)-4, TEC2xx6H-4+PIR, TEC2xx7-4, and
TEC26x7-4+PIR Series Thermostat Controllers. They are associated with the
advanced occupancy sensing capability provided by a PIR cover or a remote
occupancy sensor. These parameters allow the installer to set the thermostat
occupancy functions as required by the application.
The occupancy sensing function activates if a PIR cover is connected or if one of
the binary/digital inputs is configured to use a remote occupancy sensing device.
Table 2: PIR Cover Configuration Parameters (Part 1 of 2)
Configuration Description Selection Options
Parameter
BI2 If the BI 2 parameter is set to Door None, Door Dry, RemOVR, Filter,
Dry, the binary input is configured Service
Default: None to effectively use the advanced
functions allowed by the
installation of a door switch
contact. This function is mostly
used with fan coil units in
hospitality application.
When a door contact is used and
configured, the Stand-by timer is
no longer active. The occupancy
toggle between occupied and
stand-by is now dictated by the
door contact and the PIR cover.
• Always Occupied:
Movement detected by the

Configuration Description Selection Options
Parameter
Stand-by Heating This parameter sets the Stand-by Range: 40.0°F/4.5°C to
Setpoint heating setpoint value. 90.0°F/32.0°C
The set value of this parameter Adjustable in 0.5° increments
Default: 69.0°F/20.6°C should reside between the
occupied and unoccupied heating
setpoints. Make sure that the
difference between stand-by and
occupied value can be recovered
in a timely fashion when
movement is detected in the
zone.
Stand-by Cooling This parameter sets the Stand-by Range: 54.0°F/12.0°C to
Setpoint cooling setpoint value. 100.0°F/37.5°C
Default: 78.0°F/25.6°C The set value of this parameter Adjustable in 0.5 hour increments
should reside between the
occupied and unoccupied cooling
setpoints. Make sure that the
difference between the stand-by
and occupied value can be
recovered in a timely fashion
when movement is detected in the
zone.
Stand-by Time This parameter sets the time Range: 0.5 to 24.0 hours
delay between the moment where Adjustable in 0.5 hour increments
Default: 0.5 hours the PIR cover detected the last
movement in the area and the
time which the thermostat
stand-by mode and setpoints
become active.
Unoccupied Time If no movement is detected in the Range: 0.0 to 24.0 hours in 0.5
area and the current mode is hour increments.
Default: 0.0 hours Stand-by, this parameter sets the
time delay between the moment
where the thermostat controller
toggles to stand-by mode and the
time which the thermostat
controller unoccupied mode and
setpoints become active.
The Default value of 0.0 hours
disables the unoccupied timer.
This prevents the thermostat to
drift from stand-by mode to
unoccupied mode when PIR
functions are used
PIR Application Planning
When reviewing the application scenarios for a thermostat controller equipped
with a PIR occupancy sensing cover, consider the factors described in the
following sections.
TEC2x45-4, TEC2xx6(H)-4, TEC2xx6H-4+PIR, TEC2xx7-4, and TEC26x7-4+PIR Series Thermostat 5
Controllers Application Note
PIR Function Configuration
All PIR application-related configuration parameters are displayed in the
configuration menu or available as objects in the network object list. However, the
advanced occupancy sensing on a thermostat controller is enabled only if either:
• A PIR cover is installed on the thermostat
• A remote input is configured as a remote PIR sensor (Motion Normally Open
[N.O.] or Motion N.C.)
PIR Cover Warm-up Period
When a thermostat controller equipped with a PIR Accessory Cover is powered
on, a 1-minute warm-up period occurs before any local movements can be detected
and acknowledged by the PIR sensing device. The local status Light-Emitting
Diodes (LEDs) for the PIR cover are also inactive during that 1-minute period.
Setpoint Limitations
Occupied, Unoccupied, and Standby setpoints have the following limitations:
• Setpoint range:
- Heating setpoints: 4.5 to 32.0°C (40.0 to 90.0°F)
- Cooling setpoints: 12.0 to 37.5°C (54.0 to 100.0)°F
• Applied minimum deadband configuration
• Heat Maximum and Cool Minimum configuration parameters
You can set all individual cooling setpoints and all individual heating setpoints
independently. However, a typical arrangement always has the set value of the
standby setpoint parameters residing between the corresponding occupied and
unoccupied setpoint values.
The installer must make sure that the difference between the standby and occupied
setpoint values can be recovered quickly when local activity is detected in the
zone.

Controllers Application Note
Application Range
The PIR occupancy sensor is suitable for hospitality applications and standard
commercial applications. Both of these applications have different settings.
• Hospitality Applications benefit from the addition of an entry door switch
wired to a configured remote thermostat controller input.
When a door contact is used and configured, the Standby timer and its
configuration are no longer active or used. The occupancy status switches
between occupied and stand-by modes based on both the door contact and the
PIR sensing device.
If movements are detected by the PIR cover, the room is Always Occupied.
The room returns to Standby mode when the door switch toggles open/close.
• Commercial Applications do not usually use a remote door switch contact
attached to the thermostat.
PIR occupancy functionality is dictated by both the Stand-by Timer and
Unoccupied Timer configuration value, and the presence of movement in the
area. See the commercial application examples in the Commercial Application
Scenarios section for more information.
Unoccupied Timer Disable
In some applications, the zone may benefit from avoiding unoccupied mode and
remaining in stand-by mode when local activity is not present.
This scenario allows for advanced flexibility when used in conjunction with a
network, or when areas must remain in stand-by mode to ensure a quick response
to the sudden presence of local activity.
See Figure 2 for an example with the Unoccupied timer enabled, and Figure 3 for
and example with the Unoccupied timer disabled.

When the local PIR occupancy routine is running at the thermostat, the zone never
drifts into unoccupied mode when the unoccupied timer is set to its factory default
value of 0.0 hours.
Network Priority and Local Occupancy Routine
The PIR occupancy logic works with network commands to provide the most
flexibility while allowing for simple implementation and operation. Table 3 and
Table 4 list commands and feedback used with occupancy logic. See Table 5 for
the BACnet® objects used with occupancy logic and Table 6 for N2 objects.
Table 3: Network Occupancy Commands
State Occupancy Function
Command Level1
Local Occupancy • Releases the thermostat to its own occupancy schemes and to use
the PIR function.
• Can be a PIR sensing device, local schedule, or occupancy routine
performed by one of the digital inputs.
Occupied • Leaves the thermostat in occupied mode and cancels any local
occupancy functions, including PIR occupancy sensing.
• Forces the zone into always occupied mode.
Unoccupied • Leaves the thermostat in unoccupied mode and cancels any local
occupancy functions, including PIR occupancy sensing.
• Forces the zone into always unoccupied mode.
• Restricts local command to override if the thermostat is equipped
with the option, or if allowed by the keypad lockout.
1. Stand-By is not a commandable level. It exists only as a feedback status level.

Initial State PIR Occupancy Routine
The initial occupancy state on powerup when a PIR cover is present, or when one
of the inputs is configured for a remote PIR sensor, is always the following:
• In stand-alone applications at powerup: Stand-By (Figure 4)
• From a previous network unoccupied command: Stand-By (Figure 5)
• From a previous network occupied command: Occupied (Figure 6)
When the network 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.

Controllers Application Note
At initial powerup, when the thermostat controller 24 VAC power supply is
applied, the initial occupancy of the zone is in stand-by mode if the PIR device
does not detect any movement and no occupancy command is received by the
thermostat controller. Whenever the thermostat receives an occupied network
command, or when the PIR device detects a movement while in the local
occupancy state network command, the occupancy status switches to occupied and
the occupied setpoints are used.
If no motion is detected in the zone for the entire stand-by timer duration, the room
switches to stand-by mode and the stand-by setpoints are used. While in stand-by
mode, if no motion is detected in the zone for the entire unoccupied timer duration,
the room switches to unoccupied mode and the unoccupied setpoints are used.
Whenever the PIR device detects local motion, the elapsed stand-by timer value is
reset. If the PIR device senses local movement at any time, the occupancy status
switches to occupied and the occupied setpoints are used.
Any time the thermostat controller receives an unoccupied network command, the
occupancy status switches to unoccupied and the unoccupied setpoints are used. If
the thermostat local override function is not configured for lock out, the local user
can initiate a temporary occupied mode.
If previously in unoccupied mode when the thermostat receives a local occupancy
state network command, the local PIR occupancy loop enables. If the PIR devices
do not detect movement, the occupancy status is stand-by mode.

At initial powerup, when the thermostat controller 24 VAC power supply is
applied, the initial occupancy of the zone is in stand-by mode if the PIR device
does not detect any movement and no occupancy command is received by the
thermostat controller. Whenever the thermostat receives an occupied network
command, or when the PIR device detects a movement while in the local
occupancy state network command, the occupancy status switches to occupied and
the occupied setpoints are used.

Controllers Application Note
If no motion is detected in the zone for the entire stand-by timer duration, the room
switches to stand-by mode and the stand-by setpoints are used. While in stand-by
mode, if no motion is detected in the zone for the entire unoccupied timer duration,
the room switches to unoccupied mode and the unoccupied setpoints are used.
Whenever the PIR device detects local motion, the elapsed stand-by timer value is
reset. If the PIR device senses local movement at any time, the occupancy status
switches to occupied and the occupied setpoints are used.
Any time the thermostat controller receives an unoccupied network command, the
occupancy status switches to unoccupied and the unoccupied setpoints are used. If
the thermostat local override function is not configured for lock out, the local user
can initiate a temporary occupied mode.
If previously in unoccupied mode when the thermostat receives a local occupancy
state network command, the local PIR occupancy loop enables. If the PIR devices
do not detect movement, the occupancy status is stand-by mode.
