Figure 13: Unoccupied Timer Set to 0 Hours and Stand-By Timer Set to 2 Hours
When the local PIR occupancy routine is running at the
thermostat controller, the zone never drifts into
Unoccupied mode when the Unoccupied timer is set to
its factory default value of 0.0 hours.
Refer to the T60xDFH-4 and T60xDFH-4+PIR Series
Thermostat Controllers with Dehumidification and
Occupancy Sensing Capability Application Note
(LIT-12011569) for additional application scenarios
using various combinations of occupancy levels and
door switches.
Configuring the T60xDFH-4 and
T60xDFH-4+PIR Series Thermostat Controller
The T60x Series Thermostat Controller comes from the
factory with default settings for all configurable
parameters. The default settings are shown in Table 4.
To reconfigure the parameters via the thermostat
controller, follow the steps in this section.
1. To access the Installer Configuration Menu, press
and hold the center key for approximately
8 seconds.
Note: If the Password parameter is configured,
Password 0 appears on the thermostat controller
display indicating that the configured password is
required to proceed. Use the UP/DOWN arrow keys to
indicate the configured password, then press the
MODE key to proceed through the Installer
Configuration Menu parameters.
2. Once the Installer Configuration Menu begins,
press and release the center key to scroll through
the parameters listed in Table 4.
3. When the desired parameter is displayed, use the
UP/DOWN arrow keys to choose the desired
selection option.

4. Press and release the center key to continue
scrolling through the parameters.
Note: Pressing the FAN key during configuration
restarts the list of displayed parameters at the first
parameter listed in Table 4.
When the thermostat controller is in the Installer
Configuration Menu and left unattended for
approximately 8 seconds, the thermostat controller
reverts to the Status Display Menu.
Configuring Inputs BI1, BI2, and UI3
When BI1 and BI2 are configured for an alarm
condition, an alarm condition is displayed locally when
the input is closed. An alarm message is included on
the scrolling Status Display Menu and when the
message is displayed, the backlight momentarily
lights up.
The UI3 input provides changeover of hot/cold water
switching or supply air temperature monitoring at the
thermostat controller.
Each input can be configured to the selection options
included in Table 4.
Configuring the Sequence of Operation
(SeqOpera)
Choose the appropriate sequence of operation using
Table 2 or Table 3. The modes presented are user-
dependent on the sequence of operation selected. For
two-pipe applications using a changeover sensor,
choose the selection option (0): Cooling Only.
Changeover occurs between Cooling Only and
Heating Only. See Figure 14 through Figure 19 for
sequence of operation examples.
