Application Sheet 3 – Remote Control Using Model 76 Control

Sequence of Operation

The Model 76 Dehumidifier Control can be installed in any convenient location within the living space while the

dehumidifier is installed in the space that is going to be dehumidified such as a crawl space, attic or basement. The

relative humidity (RH) displayed on the Model 76 is the RH in the space where the dehumidifier is located – the

dehumidifier communicates this to the Model 76. Changes to the dew point setting (1 – less dry, 7 – more dry) are

made at the Model 76 and communicated to the dehumidifier. The dehumidifier can be turned on and off using the

ON/OFF buttons of the Model 76.

Once every hour the dehumidifier will turn on its blower and sample the air in the zone to be dehumidified (sampling

will also occur whenever the dew point setting is raised). If the dew point of the air is higher than the setting on the

control, the dehumidifier compressor will turn on. When the dew point of the air is below the setting on the Model 76

Control, the dehumidifier will turn off.

When the Model 76 Control is wired to the dehumidifier in this application and after completing the set up (see Set Up

the Dehumidifier for Remote Control above), “REMOTE” will appear on the display of the dehumidifier control.
