4. Under ADDITIONAL SETUP, change other
defaults if needed.
5. Under ZONE DEV INS RANGE, the default base
zone device numbers (with up to 16 zones of Sim-
plyVAV controllers) start at 1000001 as a default.
To change the default base numbers to 2000001,
3000001, or 4000001, select the desired range.
ZONE DEVICE INSTANCE
RANGE:
1M = 1000001–1000016
2M = 2000001–2000016
3M = 3000001–3000016
4M = 4000001–4000016
1M
NOTE: If the Zone Device Instance range is
changed from the default, change the
FlexStat’s Device Instance to correspond
with the range (e.g., 3000000 for a range of
3000001—3000016).
If the controllers are going to be networked, cong-
ure the system address as needed and make note of
the FlexStat MAC and Device Instance. If the system
is stand-alone, address the FlexStat for MAC 20,
Device Instance 1000000. (See Illustration 2.)
To set the FlexStat’s BACnet Device Instance (and
optionally name and location):
1. Select ADVANCED (enter password if needed)
and then DEVICE.
2. Change (or conrm) INSTANCE to 1000000.

To set protocol and parameters for BACnet commu-

1. Select ACTIVE: CONFIGURE.
2. Select MS/TP SETTINGS.
3. Change MAC ADDRESS to 20 (if needed).
4. Change MAX MASTER to 20 (or other relevant
number depending on network).*
5. Select ACTIVE: MS/TP and restart the FlexStat.
*NOTE: For a network of 16 SimplyVAV controllers,
seing the Max Master to 20 will make
the network more ecient and perform
faster. For network connections to larger
networks with other equipment, the MAC
address should be the same as the largest
MAC address in the network for maximum
performance.
NOTE: ACTIVE: CONFIGURE must FIRST BE
SELECTED before any of the values can be
changed! Otherwise values are read only.
Setpoints
The home screen displays the DAT in large numbers
(instead of room temperature that FlexStats normally
display). To change the heating and cooling DAT
setpoints, under the Main Menu, select SETPOINTS.
