Main Menu > User Settings > Sensor Calibration
The Sensor Calibration screen allows you to change the temperature calibration for the internal and any
external remote temperature sensors attached to the TZ40 WDU. You can change the temperature
calibration by +/- 7 degrees.
When the Sensor Calibration screen is selected it will show the internal and all detected remote sensors.
Each sensor found will show the current temperature (The (75) in the example screen below) and the
current number of degrees of offset being applied (1 deg in the example). “n/a” means that the remote
sensor is not attached. If the sensor’s actual temp is (74) with 0 degrees of offset and you want it to be
75, then press + to add 1 deg and it will show (75).
To change the temperature calibration, use the scroll buttons to select the internal or a remote sensor.
Once selected, use the + and – buttons to change the temperature calibration to the desired setting.
The value shown in the (xx) is the calibrated or offset temperature that you want the sensor to show.
You can update the info on this screen by pressing the right hand (blank) button.
When you close this screen, it may take a few seconds for the temperature to update to the new
temperature on the main thermostat screen.
