The PECO® TF115F-002 is a robust commercial thermostat—fully assembled, and ready
to use — for plug-in temperature control of ventilation in greenhouses, warehouses
(industrial), and/or animal con nement facilities. The rugged NEMA® 4X enclosure can
be used for cooling or heating in indoor or outdoor applications. Note: For heating
applications, see Wiring Diagram on page 2.
The PECO® TF115F-002 control, which is housed in the raintight gray NEMA 4X plastic
enclosure, uses a stainless steel coil as a temperature-sensing bulb.
Maximum sensing element withstand temperature is 145°F (62°C). Maximum temperature
for the plastic enclosure is 140°F (60°C).
Locate the thermostat about four feet (1.2 m) above the fl oor on a wall in an area with
good ventilation and an average temperature, where it will be responsive to changes in
room temperature. The unit is to be assembled with cover, gasket, and four (4) screws
installed and fully tightened (see Fig. 1). The TF115P-002 enclosure may be mounted
onto a wall or panel surface with #8 or #10 screws.
• With the plug-in inserted to 120 VAC outlet, a fan may be plugged into the series plug
(see Fig. 2) to provide temperature-related ventilation
• Power cord is attached to internal leads; default wiring is set for cooling.
• Adjustable temperature range is 40° to 110° F (4° to 43° C)
• Temperature Dial: One dial division equals 2°F (1.1° C) (See Fig. 1)
• Cord seal must remain tightened around power cord to maintain rain-tight seal; if removed,
the locking nut must be held stationary while gland nut is fully tightened (see Fig 1, 2)

Allow one hour or necessary amount of time for the thermostat and system to stabilize for
normal operation. This thermostat is factory calibrated and requires no correction on site.
By default, the TF115P-002 thermostat is wired for cooling operation.
To Check Operation:
1. Set Temperature Dial to desired temperature setpoint.
2. Plug the controlled device (e.g., fan) into the series plug (female side of TF115P plug).
3. Plug the TF115P power cord into the wall outlet. Note: Outlet must be 120 VAC.
4. To start operation, rotate Temperature Dial. Wait for the unit to turn on.
Note: For units that are wired for Cooling/Ventilation operation (default) rotate the Dial
at least ve (5) degrees below the current ambient temperature. For units that are
rewired for Heating operation, rotate the Dial at least ve (5) degrees above the current
ambient temperature.
5. Return Temperature Dial to the desired temperature setpoint. (The TF115P will
automatically control to desired temperature).

• READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO INSTALL,
OPERATE OR SERVICE THIS THERMOSTAT. Failure to observe safety information
and comply with instructions could result in PERSONAL INJURY, DEATH AND/OR
PROPERTY DAMAGE.
• Retain these instructions for future reference.
• To prevent overheating or re, use this control as an operating or regulating
thermostat. ALWAYS USE A BACKUP CONTROL OR ALARM if a control failure could
cause the controlled appliance to overheat or could cause a re.
• Do not install, use or operate if product appears damaged, the enclosure is cracked or
broken or if the sensor has been bent, crimped or is dirty.
• To avoid potential re and/or explosion, do not use in potentially fl ammable or
explosive atmospheres.
• IMPORTANT: Do not impact, dent or use the sensor for support. This will cause
calibration and/or thermostat failure.
