Backlit LCD

The T600HCx-4 and T600HCx-4+PIR Series Thermostat Controllers include a 2-line, 8-char ac te r backlit display. Low-level backlighting is present during normal operation, and it brightens when any user interface key is pressed. The backlight returns to low level when the thermostat controller is left unattended for 45 seconds.

LEDs

Three LEDs are included to indicate the fan status, call for heat, or call for cooling:

• The fan LED is on when the fan is on.

• The heat LED is on when heating is on.

• The cool LED is on when cooling is on.

Integrated PIR Sensor – T600HCx-4+PIR Series Thermostat Controllers

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 T600HCx-4 and T600HCx-4+PIR Ser i es Thermostat Controllers: the Status Display Menu, the Main User Menu, and the Installer Configuration Menu.

Status Display Menu

The Status Display Menu is displayed during normal thermostat controller operation, and continuously scrolls through the following parameters:

• Room Temperature

• Day and Time (T600HCP-4 and T600HCP-4+PIR Models)

• Schedule Status (Occupied/Unoccupied/Override [PIR Models])

• Outside Temperature – An outside air temperature sensor must be installed and 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 ther mostat controller . Access the menu by pressing the MENU key during normal thermostat controller operation.

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 – T600HCx-4+PIR Series Thermostat Controllers

A T600HCx-4+PIR Series Thermostat Controller (or a T600HCx-4 Series 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 affect 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, when installed, is auto detected.

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.

The installer must be certain that the difference between the Occupied and Unoccupie d se tpo i n ts 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 timers are adjustab le to allow for customization, as dictated by the individual space requirements. See Figure 8 for an example of increasing room temperature setpoints.

Configuring the T600HCx-4 or T600HCx-4+PIR Series Thermostat Controller

The T600HCx-4 and T600HCx-4+PIR Series Thermostat Controllers come from the factory with default settings for all configurable parameters. The default settings are shown in Table 2. To reconfigure the parameters via the thermostat controller, follow the steps in this section.
