4.5.5.3 Sensors

Figure 4-43. Service>Sensors screen.

From the Service>Sensors menu, you may access multiple display screens to enter offsets for calibrating the unit’s various temperature, humidity, and pressure sensors.

Figure 4-44. Display screens.

Additional sensor offset screens are available for optional sensors if enabled at the factory such as: Remote Supply Air Temp and Remote Supply Air Humidity.

NOTE: When calibrating sensors, an offset at one extreme may produce an error at the other extreme. Always verify that any offset is valid over the entire range of the sensor.
