WHERE TO LOCATE SENSOR
Locate the air temperature sensor in the outside air intake duct to the humidifier.
HOW TO CALIBRATE AIR TEMPERATURE SENSOR
The air temperature sensor is factory calibrated and calibration should not be necessary if the High and
Low range limits are set correctly. If a slight calibration is desired, proceed as follows:
First, determine if the INTAC
®
indication is too high or too low and by how many
degrees. This can be checked by using a probe
-
type thermometer located near the air temp
sensor and comparing the readings.
If, for example, the indicated reading is 2°F too high, a linear calibration shift can be
accomplished by adjusting both Menu 514 and 515 down 2°F. If the indicated reading is
2°F too low, adjusting both Menus 514 and 515 up 2°F will correct the error. A differential that is too large
may indicate a defective temperature sensor which should be replaced.
