Controller Points and Parameters
•
Operating Status
This box includes view only settings related to air flow. Two fan output settings can be overridden.
ECM Fan Setup
(Visible if an ECM fan is configured.) This box includes flow setpoint, maximum and minimum flow
settings, and a correction factor setting.
Current Calibration Summary
Presents the results of the two point air valve calibration along with the Minimum and Maximum Air Flow
Setpoints.
Discharge Air Reset Limits
This box contains settings that are used for Dual max VAV boxes. When the VAV's heating valve is
open, the box flow will modulate between the flow settings to control to the Discharge Air Temp Design
Setpoint.

Sensor Options
If a Symbio 500 has a wireless zone sensor and is a member of Tracer SC+ wireless link, you can install
this feature to configure the unit controller so it will communicate the wireless zone sensor battery level
to the Tracer SC+ once it is installed on the Tracer SC+. An alarm will be activated in response to a
predefined "replace batteries" state of the point.

Fan Override: Displays the Fan Override dialog box, which can be used to override the fan setting
to On.
Note: For ECM fans, the user can also select the speed of when the fan turns on.
Profile: This allows for selection between three operational programs. The three programs are
Space Temperature, Ventilation Flow, and Flow Tracking.
Box Size: Used to select a Trane F-style box size or Generic Box.
Air Damper Opens: Chose between Clockwise and Counter-Clockwise damper rotation to open the
damper.
Fan Control: Choices are None, Parallel, and Series. If Parallel or Series is selected the Fan
Setting group box will appear.
Reheat Type: Choose between reheat options of None, Hot Water, or Electric heat. If Hot Water or
Electric heat are selected the Reheat Settings group box will appear.
Parallel Fan Control: This entry will determine if a parallel fan is controlled based on zone
temperature or on flow conditions. The entry field on this line will disappear if the unit does not have
a parallel fan.
Valve Control Type (Hydronic): The choices are two-position, modulating, or both.
Location of Reheat: Choices are Local and Remote. If Both is selected for Valve Control Type, this
is used to select the location of the 2-Position valve.There is an additional binary value point to
select whether local or remote reheat has priority. By selecting Local the VAV unit will use local
reheat before remote reheat. If Remote is selected it does the opposite in that the VAV unit will use
remote heat before local heat.
Heat Control Type (Electric): Choices are Pulse Width Modulation, Staged, and SCR. Chose the
correct electric heat type.
Number of Reheat Stages (PWM or Staged): Choose the correct number of reheat stages (1-3)
