5. Align the mounting base on the wall and use the
base as a template to mark the two mounting hole
locations.
Note: Be sure to position the mounting base so that
the arrow on the base points upward to indicate the top
of the thermostat controller.
6. Drill a 5 mm (3/16 in.) hole at each of the two
marked locations and tap nylon anchors (included)
flush to the wall surface.
Note: Other means of anchoring the device may be
desired, depending on the wall medium.
7. Position the mounting base on the wall, and use
the two mounting screws (included) to secure the
base to the surface as illustrated in Figure 3.
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 mounting base.
9. Remove the screw terminal blocks as illustrated in
Figure 4.

Note: Other means of anchoring the device may be
desired, depending on the wall medium.
Wiring
CAUTION: Risk of Electric Shock.
!
Disconnect the 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 thermostat controller.
When replacing an existing thermostat controller,
remove and label the wires to identify the terminal
functions. When replacing a thermostat controller of the
same model, 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 6 mm (1/4 in.) and
connect them to the appropriate screw terminals as
indicated in Figure 5 and Table 2.
Note: If multiple wires are inserted into the screw
terminals, be sure to properly twist the wires together
prior to inserting them into the screw terminals.
2. Carefully push any excess wire back into the wall.
Seal the hole in the wall with fireproof material to
prevent drafts from affecting the ambient
temperature readings.
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.
4. Reattach the cover to the mounting base (top side
first).
5. Use a Phillips-head screwdriver to reinstall the
security screw on the bottom of the cover.
See Figure 5, Figure 6, and Table 2 for information on
wiring the thermostat controllers.
