SHORT CYCLING PROCEDURES AND TERMS USED IN DIAGNOSING When the ‘on time’ of the humidifier is less than ten minutes upon a call for humidity. To correct short cycling, all humidifiers have a capacity adjustment which allows the output of the humidifier to be reduced as low as 25% of rated output, thus extending the ‘on time’ required to maintain output. Excessive short cycling may cause higher water conductivity (mineral content) than designed for the unit.
