Application macros

Overview

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 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

APPLIC

MACRO. 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).
