To change sensor properties 
You can use the i-Vu® application or Field Assistant, if included with your system, to change sensor properties 
such as the override time or maximum setpoint adjustment. Go to Properties page > I/O Points tab > and click on 
your applicable sensor point, i.e. Space Temp, SPT Temp Sensor, Zone Temp Sensor > Details tab of microblock 
popup.
