Access to Service Tool Mode and its associated menu options is
not
protected by an access code or PIN.
However, user access must be enabled (via AV32 or the setting located in the Configuration Menu) and
the valid key sequence must be entered.
•
To enter Service Tool mode, first press the Down Arrow (
▼) and then the Up Arrow (▲), and hold
them both down for at least 5 seconds (which is the opposite sequence to the Configuration menu).
There is no PIN or password.
•
Once you have entered the valid user key sequence you will gain access to Service Tool Mode, and
SEr
will be displayed immediately along with a main menu of several options.
•
You may now use the up and down arrow buttons to navigate through the main menu options, and
the N
EXT
or P
REVIOUS
buttons to navigate the submenus and their associated options.
•
Once you have navigated to the desired item you wish to display or change, use the arrow buttons to
make any necessary changes. Once the changes are made or you wish to move on, press N
EXT
or
P
REVIOUS
.
•
If at any time you do not press a button for 30 minutes, the BACstat will exit Service Tool Mode
and return to normal display mode. Any outputs commanded manually will remain in manual, and a
VAV box commanded to various Air Balancer modes (Minimum, Maximum, Close, Open, Zero
Calibration) will also remain as commanded. A subsequent user command (
CtL
) is required to put
the BACstat and associated outputs back under control (or Auto).
