Application macros
Contents of this chapter
This chapter describes the application macros. For each macro, there is a wiring
diagram showing the default control connections (digital and analog I/O). The chapter
also explains how to save a user macro and how to recall it.
Overview of macros
Application macros are pre-programmed parameter sets. Macros change a group of
parameters to new, predefined values designed for specific applications. Use macros
to minimize the need for manual editing of parameters. Selecting a macro sets all
other parameters to their default values, except:
• Group 99: Start-up data
• 1602 PARAMETER LOCK
• 1607 PARAM. SAVE
• 3018 COMM FAULT FUNC and 3019 COMM FAULT TIME
• 9802 COMM PROT SEL
• Group 52: Panel comm and Group 53: EFB protocol
• Group 29: Maintenance trig.
After selecting a macro, additional parameter changes can be made manually using
the control panel.
Application macros are enabled by setting the value for parameter 9902 APPLIC
MACRO. By default, HVAC default (value 1) is the enabled macro.
