Daikin MD5 - Application Macros; Overview; General Considerations

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).
