DEHUMIDIFIER CONTROL SYSTEM

摘要

A dehumidifier control system is arranged to monitor changes in a relevant environmental parameter such as relative humidity (RH) over a period of time to establish a reference level, and the operation of the dehumidifier is determined by whether the current RH is above or below the established reference level. A number of individual readings of said environmental parameter are stored at intervals over said period and the reference level is set at a value where half of the stored readings fall above the reference level and half fall below. When RH is above the reference level the dehumidifier runs continuously, or at least for an extended. During low RH periods the duty cycle can be set by the user so that the dehumidifier may run for 75 % or 50 % of the time. An override condition may be selected during which the dehumidifier runs continuously. Predetermined maximum and minimum RH levels may determine whether the dehumidifier runs continuously or is permanently off.
