ABSTRACT:
A humidistat assembly of the type used in combination with an air conditioning unit incorporating an evaporator coil and an evaporator fan driven by an adequate fan motor. A sensing element is connected in direct sensing engagement with a predetermined portion of the evaporator coil wherein a current flow regulator means is disposed in circuit between the fan motor and the portion of the sensing means serving to determine the temperature or other predetermined condition of the evaporator coil. Upon the sensing of the desired predetermined condition, current is either established or prevented from flowing between a source of electrical current and the fan motor itself thereby controlling activation of the fan motor and flow of air over the evaporator coil and from the air conditioning assembly. Accordingly, activation of the evaporator fan is delayed until the evaporator coil has reached a predetermined temperature thereby decreasing the amount of water content of the circulated air.
