P15 For Units with a BACnet or LonWorks
Communications Module
Setpoint Calibration Offset (Factory set to “0”.)
• “UP” to increase offset up to +100 will raise the
MicroTech III perceived set point from the sensor.
• “DOWN” to decrease offset down to -100. This will lower
the MicroTech III perceived set point from the sensor.
Calibrate the displayed set point to the set point value sent
to the MicroTech III as follows:
1.
Set the digital room sensor displayed set point to 90° F.
2. Observe the local set point via the BAS/EMS connected
by the BACnet or LonWorks Communications Module.
3.
Adjust the Configuration Menu P15 on the sensor until
the local set point and the displayed set point are equal.
P15 For Units without a BACnet or LonWorks
Communications Module
Setpoint Calibration Offset (Factory set to “0”.)
• “UP” to increase offset up to +100 will raise the
MicroTech III perceived set point from the sensor.
• “DOWN” to decrease offset down to -100. This will lower
the MicroTech III perceived set point from the sensor.
The Setpoint Calibration Offset can be calculated using the
following formula:
ROUND [(Controller Vdd / Sensor Vdd )*1000]-1000
Example:
Given: Controller Vdd = 5.15VDC
Sensor Vdd = 4.95 VDC
The programmed Calibration Offset would be
[(5.15/4.95)*1000] -1000 = 40
