1 The Rover service tool uses the unit type to determine and download the proper default binary input configuration.
2 The run/stop binary input can be configured as a latching or nonlatching diagnostic.
3 When the supply fan is Off, the state of the fan status device is its normal state. For example, if the fan status switch (end
device) is normally open when the fan is Off, the controller should be configured for a normally open fan status input.
4 When the supply fan is Off, the state of the filter status device is its normal state. For example, if the filter status switch (end
device) is normally closed when the fan is Off, the controller should be configured for a normally closed filter status input.
