The 4655 manual digital control humidistat is designed to work with low-voltage service, providing efficient control over your humidification equipment. To determine the relative humidity in your home, slowly turn the knob on the control clockwise and counterclockwise, listening for two distinct clicks. The indoor humidity should be set to match the outdoor temperature, preventing water from running down the sides of your windows.

When the relative humidity changes, the 4655 manual digital control humidistat will automatically close the control switch. This humidistat is specifically designed to be used in conjunction with the 4655 500 humidifier, ensuring a seamless and integrated operation.

The manual digital control humidistat offers flexible installation options, allowing for either wall mounting or placement on the return plenum. This versatility ensures a convenient and customizable setup to suit your specific needs.

The even water distribution feature of the humidistat maximizes the evaporation efficiency of your humidifier, providing optimal moisture control and comfort in your living space.
