T600HPx-4 and T600HPx-4+PIR Series Heat Pump Thermostat Controllers Installation Instructions 3
Wiring
When an existing thermostat controller is replaced,
remove and label the wires to identify the terminal
functions. When a T600HPx-4 or T600HPx-4+PIR
Series Thermostat Controller is replaced, simply
remove the old screw terminal blocks and reinsert them
onto the PCB of the replacement 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 Figure 5.
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 install 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.
!
CAUTION: Risk of Electric Shock.
Disconnect power supply before making
electrical connections to avoid electric
shock.
!
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 T600HPx-4 or T600HPx-4+PIR Series
Thermostat Controller.
