Example
:
Checking the content of parameter [1-10] (to know how many indoor
units are connected to the system).
[A-B]=C in this case defined as: A=1; B=10; C=the value we want to
know/monitor:
•
Make sure the segment indication is displayed in operational default
mode as shipped from factory.
•
Push BS1 one time; result segment display:
Result: mode 1 is accessed.
•
Push BS2 10 times; result segment display:
Result: mode 1 setting 10 is addressed.
•
Push BS3 one time; the value which is returned (depending on the
actual field situation), is the amount of indoor units which are con

Changing the value of the selected setting in mode 2:
- Once mode 2 is selected (push BS1 for more than 5 seconds)
you can select the wanted setting. It is done by pushing BS2.
- Accessing the selected setting’s value is done by pushing BS3
one time.
- Now BS2 is used to select the required value of the selected
setting.
-
When the required value is selected, you can define the change
of value by pushing BS3 one time.
- Press BS3 again to start operation according to the chosen value.
Example:
Checking the content of parameter [2-18] (to define the high static
pressure setting of the outdoor unit’s fan).
[A-B]=C in this case defined as: A=2; B=10; C=the value we want to
know/change
Make sure the segment indication is as during normal operation (de-
fault situation when shipped from factory).
•
Push BS1 for over 5 seconds; result segment display:
Result: mode 2 is accessed.
•
Push BS2 18 times; result segment display:
Result: mode 2 setting 18 is addressed.
•
Push BS3 one time; the value which is returned (depending on the
actual field situation), is the status of the setting. In the case of [2-
18], default value is 0, which means the function is not active.
Result: mode 2 setting 18 is addressed and selected, return value is
the current setting situation.
