Overview Applications and Installation The KMC FlexStat series of intelligent temperature/ humidity/occupancy-sensing, wall-mounted, thermostat/controllers are native BACnet Advanced Application Controllers (B-AAC) for use in a BACnet system. The FlexStat simplifies networked zone control for common packaged HVAC equipment, such as packaged rooftop units, fan coil units, heat pumps, and other similar applications.

PAGE 14
Resetting the FlexStat Types of Reset • Restarts the controller’s Control Basic programs. If the FlexStat is not operating correctly or if a low limit alarm has occurred, the FlexStat should be reset (reinitialized). Any reset interrupts normal operation, and three types of reset exist: • Leaves configuration and programming intact. • A warm start is generally the least disruptive option (restarting normal operation the quickest). • If problems still persist, try a cold start.
PAGE 15
Restore Factory Restore Factory (restoring the FlexStat to the factory settings) does the following: • Clears present values. • Restores the object database/configuration to the defaults. • Restarts the controller’s (factory installed) Control Basic programs. NOTE: CAUTION After a return to factory defaults, applications are unconfigured. You must select the desired application and appropriate settings before connected equipment will operate properly. (See (Advanced) Application Options on page 5.
PAGE 16
Network Connection BACnet MS/TP Network Communication PC Data Port Connection Connect the network wiring and set the EOL switches accordingly. (See the Installation Guide for wiring and end-of-line switch information.) The FlexStat is equipped with a PC data port located at the bottom of the thermostat housing. This port provides a temporary EIA-485 (formerly RS-485) connection to the digital network for network setup or troubleshooting.
PAGE 17
Troubleshooting Alarm Issues Communication Issues Alarm, (False) Fan Fail Firmware Upgrade Fails • Check configuration. Be sure the Fan Status option is not selected when there is no sensor/ switch for it. • • Check that the IN2 (fan status) input pull-up resistor switches are fully latched in the correct positions. Any passive, dry contact should use the 10K Ohm setting. (See the Connections and Wiring section of the relevant BAC-10000 Series Installation Guide.
PAGE 18
Cover and Display Issues Custom Programming and Web Issues Cover Binds on Backplate Control Basic Programs Do Not Work • Carefully remove the FlexStat cover from the backplate and inspect for bent pins and/or terminal socket connectors. If cover pins are bent, use a needle-nose pliers to straighten them. If socket connectors are bent, use a pointed object (such as a thumbtack or straightened paperclip) to straighten them. (Pushing the pointed object into the socket from the back side can be helpful.
PAGE 19
Input, Sensor, and Value Issues Input Values Are Outside the Expected Range • • Check that ALL the input pull-up resistor switches are fully latched in the correct positions. See the Connections and Wiring section of the relevant BAC-10000 Series Installation Guide. A single incorrect switch position may affect multiple inputs.
PAGE 20
Output, Fan, and Relay Issues Fan Does Not Run Analog Output Does Not Work 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 3. 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.
PAGE 21
Wiring Issues • If the firmware has just been upgraded, firmware 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 firmware upgrade and ensure that the correct type of firmware is selected for the connected model. NOTE: CAUTION Do not mistakenly connect 24 VAC to an analog output ground.
