PRE-INSTALLATION
Inspection
Inspect the carton for damage. If damaged, notify the
appropriate carrier immediately. If undamaged, open the
carton and inspect the device for obvious damage. Return
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, experienced 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 ratings of the device.
Mounting
LOCATION
Locate the sensor on a wall where it will be exposed to
unrestricted air circulation, at a minimum of 15 ft./min., which
represents the average temperature of the sensed space.
Normally, the sensorislocated 5-1/2 to 6-1/2 ft.(1.7 to 2.0 m)
from floor level.
Caution: Do not locate the sensor near sources of heat or
cold, such as lamps, motors, sunlight or concealed ducts or
pipes. Avoid location where excessive vibration, moisture,
corrosive fumes 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.

Part Identification.
Wiring
Two conductor twisted pair wires (six turns per foot), Class II,
low voltage, are suitable for the sensor leads except as stated
below.
Caution: Shielded cable must be used when it is necessary
to install the sensor 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 Blue (-) lead. Do not use an
earth ground.
Do not use inside of the cover as a junction box for other
control circuits.
Restrict element lead to shortest length practical (see
Table 2).

ADJUSTMENTS
Turn the control dial knob to required setting on TS-8111
adjustable models. No adjustments are possible on TS-8101.
CHECKOUT
Measure the resistance between terminals 7 and 8 (see
Figure 1).
TS-8101 Series: 100 ohms ±0.1% at 70°F (21°C); changes
2.2 ohms per 1°F (0.5°C) at 70°F (21°C).
TS-8111 Series (see Figure 5): 1000 ohms when control dial
is set to sensed temperature.

Cover Insert Installation (See Figure 8)
1. Select appropriate cover insert.
Note: If blank insert is used, The knurled ring must be
removed from the setpoint dial. See Knurled Dial Removal
above. Also, remove dial window by sliding and/or pressing
window from front of cover.
2. Remove protective backing and protective skinon faceof

MAINTENANCE
Regular maintenance of the total system is needed to assure
sustained optimum performance. Sensors should be periodically
inspected for dirt or blockage of air over the elements.
FIELD REPAIR
These sensors are not field repairable. Replace a defective sensor
with a functional unit.
