pressurization of the space. The speed of the fan during a smoke event is user configurable for
VFD enabled units (defaults to 100%).
Fan History Statistics
The controller will collect fan history statistics and sum the total number of fan start events that
occurred in the proceeding 1 hour period. The fan history may be reset by the user. Fan history
reset may be performed locally at the unit with a BACview terminal.
Mixed Air Analog Output
For Mixed Air (MA) applications the output from the MA PID controller is used to modulate the
pre-heat air such that the entering air is not below the operation limits of the unit.
Input-5 Functionality
The controller software may be configured for single option input (IN-5) or for multiple inputs with
the addition of an input expander module. The input expander module is connected to IN-5,
providing three binary inputs at the port and essentially adding two additional inputs. The
equipment integrator must configure the input for the appropriate installed option and desired
function. The functional options provided by the input expander may be configured via a local
terminal or building automation system.
