NET
ADDRESS The NET ADDRESS item is used to select the main network
address of the individual room pressure device. Each unit on
the network must have its own unique address. The values
range from 1 to 247. If RS-485 communications are being used,
then a unique NET ADDRESS must be entered into the unit.
There is no priority between the RS-485 and keypad. The most
recent signal by either RS-485 or keypad will initiate a change.
RS-485 communications allows you access to all menu items
except calibration items. The RS-485 network can initiate a
change at any time. The RS-485 cannot override the TSI key
switch when ROOM MODE selection is key switch.
TSI key switch
A keylock switch mounted on the wall changes the pressure
between negative pressure, positive pressure, or no isolation (if
3 position switch installed).
