Siemens 1000 series Installation Instruction

Series 1000 Room Temperature Sensors,
10KΩ Thermistor (TEC and LTEC)
Product Description
These sensors work with the Terminal Equipment
Controller (TEC) and L M
ON ARK
Equipment Controller (LTEC). The sensors use a 10K ohm
thermistor to detect temperature. The effective sensing
range is 55°F to 95°F (13°C to 35°C).
Sensors that are compliant with L
are distinguishable by the LTEC name next to the MMI
jack at the bottom of the unit.
CAUTION:
TEC and LTEC sensors and cable
assemblies are not interchangeable.
NOTE:
Either sensor can be mounted on electrical
boxes, stud-type mounting brackets, or drywall.
Obtain the necessary mounting hardware and
follow the appropriate mounting procedures for
the type of installation required.
