Sensor Calibration
Leaving Load Water Temperature –
The current leaving load water temperature. R: __°F
Leaving Source Temp Sensor Calibration
– A calibration offset value that allows you to
adjust the local leaving source water temperature sensor to match a calibrated standard
that is measuring the temperature in the same location.

0°F
-9.9 to 10°F
Outdoor Air Temperature
– The current outdoor air temperature. R: __°F
Outdoor Air Temp Sensor Calibration
– A calibration offset value you can adjust so the
outdoor air temperature sensor matches a calibrated standard that measures the
temperature in the same location.

Space Relative Humidity –
Displays the current value of relative humidity sensor, if
present. Applicable if
Relative Humidity Source

R: __%
Space RH Sensor Calibration
– A calibration offset value that allows you to adjust the
space relative humidity sensor to match a calibrated standard that is measuring the
humidity in the same location.

Chiller Rotation
Rotation Method Selector - Equal Size
Daily
– Rotates the lead chiller daily at a specified time period.
Weekly
– Rotates the lead chiller weekly on a specified day and time period.
Monthly
– Rotates the lead chiller monthly on a specified day and time period.
Manual Rotation
– Manually rotates the lead chiller when the operator commands it.
Runtime
– Rotates the lead chiller after it reaches a specified number of runtime hours.
Runtime Equalization
– Rotates the lead chiller when all chillers are on and lead chiller
runtime > lag chiller runtime.
