Applications
The T60xDFH-4 and T60xDFH-4+PIR Series
Thermostat Controllers provide control of two- or
four-pipe fan coils, cabinet unit heaters, or other
equipment. These thermostat controllers provide
on/off, floating, or proportional 0 to 10 VDC control
outputs; three speeds of fan control; and
dehumidification capability. The T60xDFH-4+PIR
Series Thermostat Controllers have occupancy
sensing capability built into the device. These are
stand-alone devices that maximize up to 30% energy
savings in high-energy usage light commercial
buildings, such as schools and hotels, during occupied
times by using additional Stand-By setpoints. See the
Occupancy Sensor Operation – T60xDFH-4+PIR
Thermostat Controllers section for more information.
The non-programmable T60x Series Thermostat
Controllers provide the user access to parameters such
as system mode, fan mode, and temperature setpoints.
Additionally, the T60x Series has over 20 configurable
parameters enabling the thermostat controllers to
adapt to a variety of applications.
All T60x Series Thermostat Controllers use an intuitive,
plain text, menu-driven backlit display that makes
setup and operation quick and easy. The T60x Series
also employ a unique, Proportional-Integral (PI)
time-proportioning algorithm that virtually eliminates
temperature offset associated with traditional,
differential-based thermostat controllers.
IMPORTANT: The T60xDFH-4 and
T60xDFH-4+PIR Series Thermostat Controllers are
intended to provide an input to equipment under
normal operating conditions. Where failure or
malfunction of the thermostat controller could lead to
personal injury or property damage to the controlled
equipment or other property, additional precautions
must be designed into the control system.
Incorporate and maintain other devices, such as
supervisory or alarm systems or safety or limit
controls, intended to warn of or protect against
failure or malfunction of the thermostat controller.

This Class (A) digital apparatus meets all the
requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de la Classe (A) respecte
toutes les exigences du Règlement sur le matériel
brouilleur du Canada.
Installation
Location Considerations
Locate the T60x Series Thermostat Controller:
• on a partitioning wall, approximately 5 ft (1.5 m)
above the floor in a location of average
temperature
• away from direct sunlight, radiant heat, outside
walls, outside doors, air discharge grills, or
stairwells; and from behind doors
• away from steam or water pipes, warm air stacks,
unconditioned areas (not heated or cooled), or
sources of electrical interference
For integrated Passive Infrared (PIR) models, be sure
that the thermostat controller is located centrally , wh ere
occupant movement is abundant.

controller.
To install the thermostat controller:
1. Use a Phillips-head screwdriver to remove the
security screw if it is installed on the bottom of the
thermostat controller cover.
Note: Be sure to position the thermostat controller
mounting base so that the arrow on the base points
upward to indicate the top of the thermostat controller.
Note: Normally, the security screw comes packaged
separately in a plastic bag with the thermostat
controller. Skip this step if the screw is not installed on
the bottom of the cover.
2. Pull the bottom edge of the thermostat controller
cover and open the thermostat controller as
illustrated in Figure 1.
Note: PIR models have a wiring connection between
the cover and the Printed Circuit Board (PCB). This
connection allows for proper wiring of the occupancy
sensor. Carefully remove the wiring connection from
the PCB by pulling up on the connector block. Do not
attempt to remove the connector block by pulling on the
wires.

6. Drill a 3/16 in. (5 mm) hole at each of the two
marked locations and tap nylon anchors (included
with the thermostat controller) flush to the wall
surface.
Note: Other means of anchoring the device may be
desired, depending on the wall medium.
7. Position the thermostat controller mounting base
on the wall and use the two mounting screws
(included with the thermostat controller) to secure
the base to the wall surface as illustrated in
Figure 3.
3. Carefully pull the locking tabs on the right side of
the thermostat controller mounting base and
unlock the PCB. Open the PCB to the left as
illustrated in Figure 2.
4. Pull approximately 6 in. (152 mm) of wire from the
wall and insert the wire through the hole in the
thermostat controller mounting base.
5. Align the thermostat controller mounting base on
the wall and use the base as a template to mark
the two mounting hole locations.
Note: Be careful not to overtighten the mounting
screws.

8. Swing the PCB back to the right and carefully snap
it into the locking tabs on the thermostat controller
mounting base.

Wiring
When an existing thermostat controller is replaced,
remove and label the wires to identify the terminal
functions. When a T60x Series Thermostat Controller
is replaced, simply remove the old screw terminal
blocks and reinsert them onto the PCB of the
replacement thermostat controller.
CAUTION: Risk of Property Damage.
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.
IMPORTANT: Make all wiring connections in
accordance with local, national, and regional
regulations. Do not exceed the electrical ratings of
the T60x Series Thermostat Controller.
To wire the thermostat controller:
1. Strip the ends of each wire a 1/4 in. (6 mm) and
connect them to the appropriate screw terminals as
indicated in Table 1 and Figure 5 through Figure 9.
2. Carefully push any excess wire back into the wall.
Note: Seal the hole in the wall with fireproof material
to prevent drafts from affecting the ambient
temperature readings.
3. Reinsert the screw terminal blocks onto the PCB.
Note: If multiple wires are inserted into the terminals,
be sure to properly twist the wires together prior to
inserting them into the terminal connectors.
4. For PIR models, carefully reattach the PIR
connector to the PCB.
CAUTION: Risk of Electric Shock.
Disconnect the power supply before
making electrical connections to avoid
electric shock.
5. Reattach the thermostat controller cover to the
mounting base (top side first).
6. Use a Phillips-head screwdriver to reinstall the
security screw on the bottom of the thermostat
controller cover if desired. The security screw
comes packaged separately in a plastic bag with
the thermostat controller.

Thermostat Controller Operation Overview
Thermostat Controller User Interface Keys
The T60x Series Thermostat Controller user interface
consists of five keys on the front cover (as illustrated in
Figure 10). The function of each key is as follows:
•Use the MODE key to toggle among the system
modes available, as defined by selecting the
appropriate operation sequence in the Installer
Configuration Menu (for example, Off, Heat, Cool,
Auto).
Note: If the automatic changeover function (auto
function) is enabled in the sequence of operation
(SeqOpera), then automatic changeover heating
or cooling demand overrides the mode when
MODE = off.
•Use the FAN key to toggle among the fan modes
available, as defined by selecting the appr op ria te
fan menu options defined in the Installer
Configuration Menu (for example, Low, Med, High,
Auto).
• Use the °C/°F key to change the temperature scale
to either Celsius or Fahrenheit and allow access to
the Installer Configuration Menu. See the
Configuring the T60xDFH-4 and
T60xDFH-4+PIR Series Thermostat Controller
section.
•Use the UP/DOWN arrow keys to change the
configuration parameters and to activate a setpoint
adjustment.
Backlit LCD
The T60x Series Thermostat Controllers include a
2-line, 8-character 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 – T60xDFH-4+PIR Thermostat Controllers
The integrated PIR sensor allows for automatic
switching between fully adjustable Occupied and
Stand-By temperature setpoints without user
interaction. This feature generates incremental energy
savings during scheduled occupied periods while the
space is unoccupied.
