SPECIFICATIONS
Setpoint Dial Range: Dual marked 35 to 60°F (1.7 to 15.5°C).
Sensing Element: Vapor pressure type, copper construction.
Response: To lowest temperature sensed by any one-foo
t section
of its element. Altitude
causes the control to operate approximately 1°F colder per 1000 ft. of elevation.
Differential: 5°F (3°C) fixed.
Electrical Switch: Snap action SPDT or DPST. Refer to Table-1.
Ratings, Refer to Table-1 and
Table-2.
Connections:
TC-52xx, Screw terminals.
Mounting: In any position on any surface not subject to excessive vibration.
Housing: Molded gray PVC plastic cover with a zinc-plated steel main
enclosure with a 1/2
in. conduit opening.
Ambient Temperature Limits:
Shipping and Storage, -40 to 150°F (-40 to 66°C).
Operating, Must be 5°F (3°C) above setpoint to a maximum of 150°F (66°C) at case.
Thermal Sensing Element, 300°F (149°C).
Humidity:
Enclosure, 5 to 95% RH, non-condensing.
Thermal Sensing Element, 0 to 100% RH.
closure Rating: NEMA Type 1.
En
Dimensions:
Case, 2.7 H x 3.44 W x 1.97 D in. (69 x 87 x 50 mm).

Do not adjust the pointer beyond the highest and lowest marks on the scaleplate.
The scaleplate is only for reference, and the final settings should be verified with a
thermometer.
The terminals must not be bent, cut off, drilled, or retapped.
1. Provide a drip loop in the wiring to prevent water from reaching the thermostat.
2. Loosen the green grounding screw provided on the TC
earth ground.
3. Loosen the terminal screws and make the appropriate power wiring connections to the
numbered terminals. The TC-52xx case has an opening for a 1/2 in. conduit fitting. See
Figure-1 and Figure-2 for TC-52xx models.
4. Replace the cover.
5. Adjust the setpoint by turning the setpoint screw until the scale pointer is properly
positioned
6. Check for proper operation of the device. Follow the instructions in the Checkout
section.
7. At initial start-up of the equipment, observe the capillary for excessive vibration and
make corrections as required.
