TEC2001-4 and TEC2001-4+PIR Single-Stage Wireless Thermostat Controllers Installation Instructions

Wiring
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.
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.
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 thermostat
controller cover.
See Figure 5 for information on wiring the thermostat
controller.
!
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.
