HOA Specifications

Hardware Features
HOA switches enable points to be manually placed into HAND, ON/OFF, or AUTO
control. Analog outputs can also be placed into AUTO and ten manual control
positions.
Serial communication is made by either direct connect or through the use of a serial
HMI cable.

Default Mapping

For each type of PXC Compact (16, 24 and 36) that supports HOA and each HOA unit
(8, 16 rooftop or 16 non-rooftop UL 864), there is a default mapping between each
button and physical point.
The default mapping provides Plug-and-Play functionality. Upon connection of the
HOA Upgrade Kit to the host field panel, the HOA device is recognized and its
switches are automatically assigned to the controllers fixed digital output and fixed
analog output points. The default mapping is also used to allow the HOA board to
command physical outputs before any logical points have been defined.
