9. Remove the screw terminal blocks that are
attached to a disposable adhesive. Figure 4
illustrates the locations of the screw terminal
blocks on the thermostat controller.
Figure 4: Removing the Screw Terminal Blocks
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 Electric Shock.
Disconnect the power supply before
!
making electrical connections to avoid
electric shock.
T60xDFH-4 and T60xDFH-4+PIR Series Thermostat Controllers with Dehumidification and Occupancy
Sensing Capability Installation Instructions
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.
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.
