TEC2101-3 N2 Networked Single-Stage Thermostat Installation Instructions

Wiring
When an existing thermostat is replaced, remove and
label the wires to identify the terminal functions. When
a TEC2101-3 Thermostat is replaced, simply remove
the old screw terminal blocks and reinsert them onto
the PCB of the replacement thermostat.
To wire the thermostat:
1.
Strip the ends of each wire 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.
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 thermostat 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
cover.
!
CAUTION: Risk of Electric Shock.
Disconnect power supply before making
electric 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 TEC2101-3 Thermostat.

If using the same power source
for the thermostat and heating loads,
install a jumper across RC and RH.
