To adjust the minimum position setting and check out the economizer, the power must be connected.
1. Close the unit disconnect and place the zone sensor fan selector in the fan ON position and the heat/cool selector in the OFF position. This will place the damper in the minimum ventilation position.
2. To adjust the minimum position setting for the required ventilation air, use the Symbio™ Service and
Installation of the mobile app or Symbio™ 700 on-board UI to adjust the economizer minimum position setpoint BAS in the Fresh/Return Air settings menu. The damper will open to this setting each time the blower circuit is energized.
- When adjusting the minimum position, the damper may move to the new setting in several small steps. Once the damper has remained in position for 10–15 seconds without movement, it can be assumed it is at the new position.
3. Replace the filter access panel.
- The damper will close when the blower circuit is de-energized.
