Fan Does Not Run

NOTE: The animated fan icon is coupled with
BV18 in the packaged programming (not
the actual fan output terminal).
• Select Occupied mode from the Home Menu—
see H/C, Fan, Occupancy, and Override on page
• Override the fan to On from the Home Menu—
see H/C, Fan, Occupancy, and Override on page
• See Wiring Issues on page
• Check that the appropriate application is se-
lected—see (Advanced) Application Options on
page 6.
• Check the fan configuration—see Fan Setup on
page 6.
• Restart the FlexStat. After a low limit alarm is

Relay (Internal) Does Not Work

CAUTION
Relays are for Class-2 voltages (24 VAC) only.
Do not connect line voltage to the relays!
NOTE: Max. output current is 1 A for individual
relays @ 24 VAC/VDC or a total of 1.5 A
per bank of 3 relays (relays 1–3, 4–6, and
7–9). Do not attach a device that draws
current that exceeds the corresponding
value. Relays are NO, SPST (Form "A").
• Check current draw of load. Substitute an output
device that draws less current.
• Check that the output is on.
• See Wiring Issues on page
• Restart the FlexStat.
• If Restore Factory has just been performed, see
the Note and Cautions in Restore Factory on
page 17.
• If the firmware has just been upgraded, firm-
ware for the wrong model type may have been
installed (e.g., BAC-1xx63 firmware accidentally
installed in a model BAC-1xx36). In the About
menu, ASV may simply read "CUSTOM" instead
of something like "BAC_1xx36 R1.1.0.5" as it
normally would have done. If so, repeat the firm-
ware upgrade and ensure that the correct type of
firmware is selected for the connected model.
NOTE: ASV in the About menu will also show
CUSTOM if any built-in Control Basic
program (1–5) is not running or has auto-
run disabled.
