Application Macros
Overview
Macroschangeagroupofparameterstonew,predened
valuesdesignedforspecicapplications.Usemacros
to minimize the need for manual editing of parameters.
Selecting a macro sets (always use HVAC Defaults) all other
parameters to their default values, except:
• Group99:Start-upDataparameters(exceptparameter
9904)
• The PARAMETER LOCK 1602
• The PARAM SAVE 1607
• The COMM FAULT FUNC 3018 and COMM FAULT
TIME3019
• TheCOMMPROTSEL9802
• Groups 51…53 serial communication parameters
• Group29:Maintenancetriggers
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APPLICMACRO.Bydefault,HVACDefault
(value 1) is the enabled macro.
General Considerations
The following considerations apply for all macros:
• When using a direct speed reference in AUTO mode,
connect the speed reference to analog input 1 (AI1),
and provide the START command using digital input 1
(DI1). In HAND/OFF mode, the control panel provides
the speed reference and START command.
• When using process PID, connect the feedback signal
to analog input 2 (AI2). As a default, the control panel
sets the Setpoint, but analog input 1 can be used
as an alternate source. You can set up process PID
using parameters (Group 40) or using the PID control
assistant (recommended).
