Installing the Humidity Control (P/N 611224)
The mechanical Humidity Control controls excess humidity. When the
rate of humidity is greater than the value indicated on the adjustment
knob, activate the high-speed switch and, if needed, the interior-exterior
exchange switch. When the appropriate humidity rate is reached, the
humidistat returns to its pre-selected ventilation mode.
The Humidity Control (P/N 611224) should be installed on the wall.
Note: If the dehumidistat is used to sense bathroom humidity during
a shower, it should be mounted high on a wall near the shower or tub for a faster response.
It should also be set to a higher relative humidity (70-80%) to avoid unnecessary high-speed
exhaust due to general changes.
1. Run a 2-conductor electrical wire through the wall until it reaches the appliance’s
housing.
