Thermostat Installation
Warning!
Before installing the Thermostat Control, disconnect and lock out all power to heater!
Note: For Multiple fans/heaters on one bin
If installing two heaters on a bin you will need to disconnect the existing Thermostat Controls (TC-100) from the
heaters and install (1) TC-400 Thermostat Control (S19995). The TC-400 will need to be wired to control both
heaters at the same time and will require its own 120VAC incoming power. See TC-400 Schematic on pages 28-
29 on how to connect TC-400 Thermostat control to multiple heaters. Contact Sioux Steel or your dealer to order
the TC-400 Thermostat Control (S19995).
Handle the control carefully. Take care not to kink or damage the capillary tube.
Note:
Before choosing where to mount the control to the bin, be sure the electric cord of the control will reach the
heater control panel. The preinstalled cord is approximately 11’-6” in length.
Mount the control on the bin sidewall between the perforated floor and the concrete foundation, three feet to the
side of the transition or Triumph fan. Tape the enclosed template (found in back of manual) to the bin wall so the
top two mounting holes locate on a corrugation ridge. Mark and drill the holes as shown. Location of the ½” hole
is critical for proper alignment with the thermometer stem. Improper alignment will damage the thermometer.
The sensing element remains inside the control (outside the bin.)
Using self-drilling screws (customer supplied), fasten the control to the bin wall, taking care not to damage or
bend the stem of the thermometer. Neoprene rubber or foam insulation (customer supplied) should be used around
the top and sides of the control where it fastens to the bin wall
. Do not seal bottom of control

is where the air must exit.
