Integrated PIR Sensor –
TEC2004-4+PIR Thermostat Controller
The integrated PIR sensor allows for automatic
switching between fully adjustable Occupied and
Unoccupied temperature setpoints without user
interaction. This feature generates incremental energy
savings during scheduled occupied periods while the
space is unoccupied.
Programming Overview
Three menus are used to view, program, and configure
the TEC2004-4 and TEC2004-4+PIR Thermostat
Controllers: the Status Display Menu, the Main User
Menu, and the Installer Configuration Menu.
Status Display Menu
The Status Display Menu displays during normal
operation. This menu scrolls through several
parameters:
•
Room Temperature
•
System Mode
•
Schedule Status (Occupied/Unoccupied/Override)
•
Outdoor Temperature – An outdoor air temperature
sensor must be connected.
•
Applicable Alarms – The backlight lights up as an
alarm condition is displayed.
Note: Press the YES key to temporarily stop this
menu from scrolling.
Note: An option is available within the Installer
Configuration Menu to lock out the scrolling display and
show only the Room Temperature parameter.
Main User Menu
Use the Main User Menu to access and change the
basic operating parameters of the thermostat controller.
Access the menu by pressing the MENU key during
normal thermostat controller operation.

Installation Instructions
Installer Configuration Menu
Use the Installer Configuration Menu to set up the
thermostat controller for application-specific operation.
To access the menu, press and hold the MENU key for
approximately 8 seconds.
Occupancy Sensor Operation –
TEC2004-4+PIR Thermostat Controller
A TEC2004-4+PIR Thermostat Controller (or a
TEC2004-4 Thermostat Controller equipped with a PIR
accessory cover) provides advanced occupancy logic.
Note: The PIR strategy is an occupied strategy. If the
thermostat controller is programmed to be Unoccupied,
the PIR function does not have an effect on the
occupancy strategy.
The thermostat controller automatically switches the
occupancy level between Occupied and Unoccupied as
required, when local movement is sensed. In the
Occupied mode, if no movement is detected beyond
the Unocc TM parameter setting, the mode changes to
Unoccupied. Once movement is detected, the mode
changes back to Occupied.
Occupancy sensing is enabled only if a PIR cover is
installed. The PIR cover is auto detected when
installed.
PIR Diagnostic LEDs
The diagnostic LEDs inside the PIR lens brighten when
movement is detected within the first 30 minutes after
powerup. The LEDs do not light up or brighten after the
initial 30-minute period.
Setpoints
The installer must be certain that the difference
between the Occupied and Unoccupied setpoints can
be recovered within a timely fashion to ensure
occupancy comfort. In addition, the difference between
the two setpoints must be large enough to warrant
maximum energy savings.
These setpoints and Unoccupied time are adjustable to
allow for customization, as dictated by the individual
space requirements. See Figure 7 for an example of
increasing room temperature setpoints.
