PRE-INSTALLATION
Inspection
Inspect the car ton for damage. If damaged, notify the
appropriate carrier immediately. If undamaged, open the
carton and inspec t the device for obvious damag e. Ret urn
damaged products.
Required Installation Items
• Wiring diagrams
• Tools (not provided):
DVM (digital volt-ohm meter)
Appropriate screwdriver for mounting screws and termi-
nal connections
• Appropriate accessories
• Mounting screws, two (2) provided for securing to a 2 x 4
conduit box
INSTALLATION
Caution:
• Installer must be a qualified, experi enced technician.
• Make all connections in accordance with the wiring
diagram, and in accordance with national and local
electrical codes. Use copper conductors only.
• Do not exceed ratin gs of t he de vice.

Mounting
LOCATION
Locate the sensor on a wall where it will be exposed to
unrestricted air circulati on, at a minimum of 15 ft ./min., which
represents the average temperature of the sensed space.
Normally, the se nsor is lo cated 5- 1/2 to 6- 1/2 f t. (1. 7 to 2. 0 m)
from floor level.
Caution:
cold, such as lamps, motors, sunlight or concealed ducts or
pipes. Avoid location where excessive vibration, moistu re,
corrosive f um es or vapors are present. NEMA Type 1 covers
are intended for indoor use primarily to provide a degree of
protection against contact with the enclosed equipment.
Do not locate the sensor n ear sources of heat or

Wiring
Two conductor twisted pai r wires (six turns per f oot), Class I I,
low volta ge, ar e suita ble f or t he sensor leads ex cept a s sta ted
below.
Caution:
to install the sen sor lead in the same conduit with power
wiring, or when it is known that high RFI/EMI generating
devices are near. System ground the shield at the controller
only on the COM (-) terminal or Blu e (-) lead. Do not use an
earth ground.
Do not use inside of the cover as a junction box for other
contro l circuits.
Restrict element lead to shortest length practical (see
Table 2).

ADJUSTMENTS
Turn the control dial knob to required setting on TS-8111
adjustable mode ls. No adjustments are possible on TS-8101.
CHECKOUT
Measure the resistance between terminals 7 and 8 (see
Figure 1).

MAINTENANCE
Regular maintenance of the total system is needed to assure
sustained optim um performance. Sensors should be periodically
inspected for dirt or blockage of air over the elements.
FIELD REPAIR
These sensors ar e not fi eld repai rable. Replace a defecti ve sensor
with a functional unit.
