Fans Tab

Select the Fans tab to configure the fan settings.

1.Select Available for each fan that is connected to the CMC. If a fan that is not connected is shown as available, the CMC will erroneously detect an alarm condition and send alerts.

2.Enter the temperature at which fans turn on in the Start At field.

3.Set the operating range for the fan in the Hysteresis field. For example, if the Hysteresis value is set to 8° F and the Start At value to 75° F, the fan switches on when the temperature reaches 75° F and switches off when the temperature has decreased by 8° F (to 67° F).
