FlexStat 36 Operation Guide, Rev. R

Output, Fan, and Relay Issues

Analog Output Does Not Work

CAUTION

Do not mistakenly connect 24 VAC to an analog

output ground. This is not the same as a relay’s

switched common. See the backplate’s terminal

label for the correct terminal.

NOTE: The maximumcurrentofananalogoutput

is20mA@12VDC. Excessive loads will

be clamped at the maximum. Relays may

chaer or fail to latch if they need more

current than the maximum allowed. KMC

REE-3111/3112 relays, for example, could be

connected to the analog outputs, but REE-

3211/3221/3213 relays would not operate

reliably with analog outputs because their

required power exceeds the FlexStat’s

capacity. (REE-3211/3221/3213 relays could,

however, be used with the FlexStat relays

and a separate power source.)

• Check current draw of load—it must be 20 mA or

less. Substitute an output device that draws less

current.

• Check that the output is on.

• See Wiring Issues on page 39.

• See also Fan Does Not Run on page 36.

• If Restore Factory has just been performed, see

the Note and Cautions in Restore Factory on

page 27.

• If the rmware has just been upgraded, rm-

ware for the wrong model type may have been

installed (e.g., BAC-1xx63 rmware 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 rm-

ware upgrade and ensure that the correct type of

rmware 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.

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 4.

• Override the fan to On from the Home Menu—

see H/C, Fan, Occupancy, and Override on page 4.

• See Wiring Issues on page 39.

• Check that the appropriate application is select-

ed—see (Advanced) Application and Additional

Setup on page 7.

• Check the fan conguration—see Fan Setup on

page 8.

• Restart the FlexStat. Afteralowlimitalarmis
