HPD0460BN Multi-Function Room Units, BACnet MS/TP
FW4.02
The HPD0460BN devices may be used as BACnet networked HVAC devices or standalone; as an HMI
for control and display of multiple controllers on a local network, as a controller with high flexibility for
user configuration to suit a wide variety of control applications or as a network manager including multi-
zone annual time scheduling. The display is programmable to indicate user specific text and dynamic
data points. Data points may be adjusted directly at the LCD (parameters such as set-points, fan-
speeds and manual overrides). The text and dynamic values for each of the 32 user lines may be set as
small font size or large font size.
The user push-buttons, indication LED’s and an audible sounder may be independently programmed to
suit the user application. Physical I/O points may be used in the system independently or, subject to the
version, by the internal control loops and logic blocks.
Depending on the version, logic function blocks enable easy configuration of a variety of functions
including Economy Changeover (temperature or enthalpy), VAV Volume, Occupancy, Hours Run
monitoring, Minutes Run monitoring, Lead/Lag changeover, instantaneous Power calculation (kW, BTU)
and a wide array of hysteresis & dead-band/live-band choices (Compare function).
The time clock version features a 365 day clock/calendar with four channel time-switch, 20 holidays
(one-off or annually recurring) and summer/winter time.
