WTC32ND TEMPERATURE CONTROLLER
To adjust the I TERM, use an ohmmeter to measure resistance
between Test Points 6 & 7 (TP6 & TP7).
Adjust the I TERM trimpot to the desired resistance, see
Table 5 for suggested starting points. An online design
calculator is available to assist in determining resistance
values.

Or use Equation 3 to calculate the I TERM trimpot resistance.
Equation 4 shows how to calculate the I TERM, given the
trimpot resistance.

INSTALL THE WTC32ND ON THE WTC32ND-EV
EVALUATION BOARD
The notch at the top of the WTC32ND must
be oriented at the top of the Printed Circuit
Board (PCB). This orientation places PIN 1 in
the upper left corner. See Figure 11 below
for proper orientation.

1. Match up the notch on the WTC32ND with the silkscreen
on the PCB.
2. Align the pins with the sockets, ensuring that all pins are
lined up in their respective sockets.
3. Press firmly to seat the WTC32ND.
4. Attach the snap-in standoffs. See Figure 12.
