    • If there is a loss in communication to any of the TZ controllers, BV24 will indicate a MS/TP fault, AV 41 will = - 40 °F and the fan, heating and cooling will be disabled, and the TZ100 TZ200 damper will return to minimum position. NONE 12345678 www.lynxspring.com...

    During unoccupied mode and a call for cooling, the damper will modulate open to Max Air Flow setpoint (configurable), maintaining the Unoccupied Cooling Setpoint (80°F). Unoccupied Heating Control During unoccupied mode and a call for heating, the damper will modulate closed to Min Air Flow setpoint (configurable), maintaining the Unoccupied Heating Setpoint (65°F). www.lynxspring.com...
  • Page 12 When placed in this mode, the outputs will be allowed to modulate or cycle from 0-100% (100%). A network variable can modify this setpoint. Fan Status The fan status of the primary unit can be used as proof of airflow as status or to prevent outputs from operating when no airflow is detected. Set Aux Output A-E Authorization Fan Status or Fan+MaxPwr. www.lynxspring.com...
  • Page 13 If modulating fan is chosen, there is an ECM Minimum Speed setting that can be adjusted in Onyxx LX UI below Output C. The default is 30%. Ramp adjustment boxes below Aux A thru Aux E Ramp settings are preset to manufacturer recommendations. Adjustments can be performed at user risk and may result in undesirable behavior. www.lynxspring.com...
  • Page 14 If the measured reading from the TZ200HC zone sensor reaches within 100ppm greater than the CO2 setpoint [AV66], the fan and damper will modulate toward normal operation in the BZ controller. Once the measured reading from the TZ200HC zone sensor is less than the CO2 setpoint [AV66], the BZ controller returns to normal operation. www.lynxspring.com...
  • Page 15 95 sec. There is a reference to AV-46 thru 50 but this does not write to the Private VAR. Do not write to these AVs in BACnet to adjust the runtime. Adjustment is solely through the Onyxx LX UI. www.lynxspring.com...
  • Page 16 If the measured zone dewpoint (which requires a Humidity input] exceeds the entering chilled water temp (this must be selected to utilize this sequence) the BZ controller will close the entering chilled water temperature. If the zone dewpoint rises above the dewpoint high limit, the ventilation damper will be modulated further open until the zone dewpoint drops back below the dewpoint low limit. www.lynxspring.com...
