To calibrate your ETOG sensor and ensure accurate temperature readings, follow these steps: First, disconnect the sensor from terminals 11 and 12 on your ETO2 controller, which handle sensor heating. Next, allow the sensor to acclimate to the ground temperature by waiting a few hours. Use a reliable thermometer to measure the actual ground temperature where the sensor is located, and then compare this measurement with the temperature shown on your ETO2 controller. Determine the temperature difference, and then program this offset into the controller using the encoder button to match the real temperature. Finally, reconnect the sensor to terminals 11 and 12. Remember, the ETO2 controller always displays the ETOG sensor's core temperature. Proper calibration is crucial for the effective performance of your ice and snow melting system, providing accurate readings for optimal control.
