4 Air Temperature Probe Offset
As standard, the air temperature probe is located on the door frame, inside the walk-in. The WIMS 100 will
display the air temperature at that particular location ONLY. However, WIMS 100 can be adjusted to estimate
the temperature of a remote location inside the walk-in.
4.1 Calculating the Probe Temperature Offset
 Establish the location inside the walk-in where you want to monitor the air temperature. Ex: Return Air
Temperature (behind the evaporator)
 Using a calibrated thermometer, measure the air temperature at that particular location. T
MEASURED
 Read the air temperature on the display of WIMS 100. T
WIMS 100
 The temperature difference between the two temperatures is the temperature offset. T
