Automatic Humidistat Digital

The new Aprilaire #60 automatic humidifier control works in conjunction with your furnace to control the operation of the humidifier. The control senses indoor RH and outdoor temperature and automatically adjusts the operation time of the humidifier to provide the optimum humidity level in the home. The digital readout on the control displays the RH level inside the cold air return. This humidistat can also be used in manual mode when it is not possible to run wire to outdoor sensor.
