Increase/decrease (floating) outputs on Xenta 121s resynch to 0 at least every 18 hours.
- Xenta 121-HP
- Xenta 121-FC
Resynchronizing outputs ensures that the actuator is at the same position the programming thinks it is and allows for more accurate control.
Consider forcing Xenta 121s to unoccupied at least every 12 to 16 hours, even in a 24-hour facility. This will allow time for the valve to resynch while the fan is stopped and all dampers are shut. If the valve is resynchronizing during a time when pulling in unconditioned air could take the space outside of the deadband, it's better to control when the resynch happens.
