BS4~12A14AJV1B
VRV 5 branch selector unit
4P670163-1 – 2022.02
What
How
Changing and accessing
the setting in mode 1
Once mode 1 is selected (push BS1
one time), 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.
To quit and return to the
initial status
Press BS1.
Example
Checking the content of parameter [1‑2] (to know the software
version).
[Mode-Setting]=Value in this case defined as: Mode=1; Setting=2;
Value=the value we want to know/monitor:
1
Make sure the 7‑segment display indication is in the default
situation (normal operation).
2
Push BS1 one time.
Result:
Mode 1 is accessed:
3
Push BS2 two times.
Result:
Mode 1 setting 2 is addressed:
4
Push BS3 one time; the value which is returned is the software
version.
Result:
Mode 1 setting 2 is addressed and selected, return
value is monitored information
5
To quit mode 1, push BS1 one time.
16.1.6
To use mode 2
Mode 2 is used to set field settings of the BS unit.
What
How
Changing and accessing
the 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 1 time.
To quit and return to the
initial status
Press BS1.
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 1 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 1 time.
▪ Press BS3 again to start operation
according to the chosen value.
Example
Checking the content of parameter [2‑7] (to enable or disable the
ventilated enclosure function).
[Mode‑Setting]=Value in this case is defined as: Mode=2; Setting=7;
Value=the value we want to know/change.
1
Make sure the 7‑segment display indication is in the default
situation (normal operation).
2
Push BS1 for more than 5 seconds.
Result:
Mode 2 is accessed:
3
Push BS2 seven times.
Result:
Mode 2 setting 7 is addressed:
4
Push BS3 1 time; the value which is returned (depending on the
actual field situation), is the status of the setting. In the case of
[2‑7], the default value is "1", which means the ventilated
enclosure function is enabled.
Result:
Mode 2 setting 7 is addressed and selected, return
value is the current setting situation.
5
To change the value of the setting, push BS2 till the required
value appears on the 7‑segment display indication. When
achieved, define the setting value by pushing BS3 one time. To
start operation according to the chosen setting, confirm again
by pushing BS3.
6
To quit mode 2, push BS1 one time.
16.1.7
Mode 1: Monitoring settings
[1-0]
Shows the remaining lifetime of the R32 sensor.
The remaining lifetime is displayed in months ranging from 0 to 120.
INFORMATION
The sensor has a lifetime of 10 years. The user interface
displays error "
CH-22
" 6 months before the end of the
sensor lifetime and error "
CH-23
" after the end of the
sensor lifetime. For more information, see the reference
guide of the user interface and contact your dealer.
16.1.8
Mode 2: Field settings
[2-0]
Setting to define if the BS unit belongs to a cluster or not.
In case the BS unit belongs to a parallel or series cluster, this setting
has to be put on "1" to enable it. See
This setting must be made on all main PCB's (A1P, A2P and A3P) of
the BS unit.
[2-0]
Definition
0 (default)
Cluster disabled
1
Cluster enabled
[2-1]
Setting to define the cluster number the BS unit belongs to.
In case there are multiple clusters in the system, all BS units
belonging to the same cluster need to have the same cluster number
as value for this setting. BS units belonging to different clusters need
to have a different cluster number.
This setting must be made on all main PCB's (A1P, A2P and A3P) of
the BS unit.
[2-1]
Definition
0 (default)~15
Cluster number
[2-2]
Setting to define the cluster configuration the BS unit belongs to.
This can be either a parallel or series cluster. This setting must be
made for all BS units in the same cluster, and has to be the same
value. See
"12.3 To determine the required safety measures"
This setting must be made on all main PCB's (A1P, A2P and A3P) of
the BS unit.
