Wiring
!
CAUTION: Risk of Electric Shock.
Disconnect power supply before making electrical
connections to avoid electric shock.
Note:
When replacing an existing thermostat,
remove and label wires to identify terminal
designations. When replacing a TEC2104-1
thermostat, simply remove the terminal blocks and
reinsert onto the new thermostat.
To wire the thermostat:
1. Strip each wire 1/4 in. (6.35 mm) and connect to
the appropriate terminal according to the
TEC2104-1 wiring diagram (Figure 5).
2. Gently push excess wire back into the wall, plug
the wall hole with fireproof material to prevent
drafts from affecting ambient temperature
readings, and install screw terminal blocks back
onto the PCB.
3. Reattach the thermostat cover to the installed
base (top side first) and install the security screw
on the bottom.
!
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.
