model 70 living space control

The Model 70 Living Space Control contains its own sensors that override the main control sensors on the dehumidifier. The purpose of utilizing the Model 70 is to have the dehumidifier control located in a living area, where the homeowner can monitor and control humidity levels.. Once connected and powered, the Model 70 is automatically recognized by the dehumidifier and will continuously communicate the air conditions and the dew point setting to the dehumidifier control.. No sampling is needed when using a Model 70 because the control is located in the space to be conditioned and is measuring the dew point in that space.. Refer to the Model 70 Installation Instructions for location and mounting instructions.. The Convertible configuration is not available with the Model 70 Living Space Control..
