HOA Control Button
The HOA (Hand-Off-Auto) button is used for two functions:
to quickly access the Control page and to easily change
between the Hand (Keypad), Off, and Auto (Remote) control
places.
Control Place
The control place is the source of control where the drive can
be started and stopped. Every control place has its own
parameter for selecting the frequency reference source. In
the HVAC drive, the
Hand control place is always the keypad.
The Auto control place is determined by parameter P2.1.1
(Keypad, I/O Terminal, I/O three-wire, or Fieldbus CTRL). The
selected control place can be seen on the status bar of the
keypad.
Local Control
The keypad is always used as control place while in hand
control. Hand control has higher priority than auto control.
Therefore, if, for example, bypassed by parameter P2.1.17
through digital input while in
Remote , the control place will
still switch to Keypad if Hand is selected. Switching between
Hand, Off, and Auto Control can be done by pressing the
HOA button on the keypad.
Changing Control Place
Change of control place from Hand to Auto (keypad).
1. Anywhere in the menu structure, push the HOA button.
2. Push the arrow up or the arrow down button to select
Hand/Off/Auto and confirm with the OK button.
3. On the next display, select Hand , Off , or Auto and again
confirm with the OK button.
4. The display will return to the same location as it was
when the
HOA button was pushed. However, if the
Remote control place was changed to Hand (Keypad)
you will be prompted for keypad reference.
