LX Series Unit Ventilator Controller User's Guide 73
Optimum Start
Optimum Start prepares the space for occupancy in advance of the occupied
period. The Unit Ventilator Controller uses stored daily statistics to calculate the
length of time required each day to reach the occupied setpoints just as actual
occupancy begins.
See the primary Optimum Start section for more information.
Note: For Optimum Start to work, the network variable nviOccCmd must be set
to SNVT type SNVT_tod_event. You can set this using the Changeable Nv
Manager view of the device in FX Workbench.

Field Description
Heating
Occupied/Bypass
Displays the heating setpoint for the occupied and bypass states.
Standby
Displays the heating setpoint for the standby state.
Unoccupied
Displays the heating setpoint for the unoccupied state.
Maximum Discharge
Temperature
Displays the highest discharge air temperature you allow during the
heating state.
Minimum Heating
Time
Displays the length of time that the duct and perimeter heating must stay
ON once it has turned ON, and the length of time that the heating must
stay OFF once it has turned OFF. Minimum heating time affects duct
heating, perimeter heating, and staged outputs. Once a staged output has
changed state, the next staged output cannot change state until the
minimum heating time has passed.
Note:
Minimum Heating Time does not apply to modulated heating.
