Placement: The Thermalarm’s temperature sensor is included in the unit, so placement of the Thermalarm should be at the site where you wish to monitor the temperature.
Temperature Alarm Set Points: To set the temperature alarm set-points, move the red “set” hands by moving the red knobs at the bottom of the unit to the desired high and low set-point making sure the temperature indicating hand (black) is between the two red set hands. You should have a five to ten degree difference between the normal temperature and your alarm set-points.
