OPERATING INSTRUCTIONS – digital humidifier control

The Digital Humidifier Control offers two modes of operation, Automatic or Manual. An explanation of both modes follows. (See Figure 2 on page 10 for Automatic Mode. See Figure 3 on page 11 for Manual Mode.)

When in the Automatic Mode, this system offers the following benefits:

•You will receive the optimum amount of humidity so that your home and its furnishings are protected from the damaging effects of excess condensation or low humidity during the heating season. The Control automatically adjusts your home’s humidity based on the outdoor temperature, increasing the time maximum comfort is maintained..

•Simple operation with few adjustments. In the Automatic Mode, the Control eliminates the need to manually adjust the control when outdoor temperature changes. It also eliminates the need to turn the dial setting to “OFF” during the summer season.

Digital Humidifier Control Indicator Lights

Call Dealer for Service: The red light indicates that the humidifier is not operating normally and that service is required.

Humidifier On: The green light indicates that the humidifier is operating normally..

Blower Activation

Set the Blower Activation Switch to “ON” to allow the Humidifier Control to activate the furnace fan for additional humidification. Refer to TABLE 4 – Operation Guide. This may be required if the humidifier is mounted on a heat pump or a furnace with short run cycles.

When the Blower Activation switch is “ON”, the Humidifier Control will turn on the HVAC blower when humidity is required. In the “OFF” position, the humidifier will only operate if humidity is required and the HVAC system is operating..

When the Blower Activation switch is “ON”, the Humidifier Control may periodically turn the HVAC blower on to sample the humidity of the air.
