N2 Occupancy Mode Input

Translates the OCCSCHED command from a supervisory device to the Occupancy Schedule input of the Occupancy Mode determination. It also allows the OCCTIME to be entered in minutes and then converts it to seconds for Occupancy Mode determination.

N2 VAV Box Mode Input

Translates the VAV Box Mode Input and the Water Flush Input into the outputs required for a third-generation VAV application. The VAV Box Mode Input uses the Box Mode Enum Set, which includes Shutdown Closed, Shutdown Open, Warmup, Water System Flush, Low Limit, Satisfied, and Cooling and Heating. The outputs provided are System Mode, Unit Enable, and WarmupCooldown. The Occupied Sequencer switches between Satisfied, Cooling, and Heating in the current VAV single duct application. As a result, when the VAV Box Mode is commanded to Satisfied, Cooling, or Heating, the System Mode is set to Auto.

N2 Common Outputs

Translates the VAV Controllers' Cooling Control status into Inadequate Cooling, the Heating Control status into Inadequate Heating, the Damper Control Status and the Exhaust Damper Control Status into Starved Exhaust Box, and the Autocalibration Status into Autocal Active. These statuses match the items provided by the N2 VMA14xx Series Controllers.

N2 Common Outputs - SD VAV ASC

Translates the VAV Controllers' Cooling Control Status into Inadequate Cooling, the Heating Control Status into Inadequate Heating, the Damper Control Status and the Exhaust Damper Control Status into Starved Exhaust Box, and the Autozero Status into Autocal Active. These statuses match the items provided by the N2 VAV100 Series Controllers.

N2 VAV DD Common Outputs

Translates the VAV Controllers' Cooling Control Status into Inadequate Cooling, the Heating Control Status into Inadequate Heating, the CD Damper Control Status into Starved Cold Duct, the HD Damper Control Status into Starved Hot Duct, and the Autocalibration Status into Autocal Active. These outputs are used by the N2 VMA14xx Series Controllers. This module is implemented as a standard Control Activity.
