When shipped the Thermostat will have a red rubber sealant covering the calibration screw. See image below.
This Red rubber sealant must be removed to access the calibration screw. The image below shows the area after the sealant has been removed.
Next use a small cross-tip screwdriver to make adjustments to the calibration screw.
NOTE: Hold the outer shaft firmly while making adjustments to the calibration screw.
To increase the Vapor Steamer temperature turn the calibration screw Counter-Clockwise (CCW).
To decrease the Vapor Steamer temperature turn the calibration screw Clockwise (CW).
