Appendix 1 Air Temperature Probe Offset - American Panel Walk-in Monitoring System 200 Owner's Manual

14. Appendix 1 Air Temperature Probe Offset

By default, the air temperature probe is located on the door frame, inside the walk-in. The WIMS 200 will
display the air temperature at that particular location ONLY. However, WIMS 200 can be adjusted to estimate
the temperature of a remote location inside the walk-in. To take advantage of this feature, set the air temperature
probe offset. To do so, you will have to enter the technician menu (see Chapter 5.).
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
 Read the air temperature on the display of WIMS 200. T
 The temperature difference between the two temperatures is the temperature offset. T
Ex:
Return Air Temperature (measured behind the evaporator)
WIMS 100 Displayed Temperature
The Temperature Offset will be: (-5
Note:
The air probe temperature offset is not to be use to make up for undersized or defective refrigeration
systems. If a different temperature is desired inside the walk-in, contact a refrigeration technician to
adjust your refrigeration system.
Special care should be taken when adjusting the air probe temperature offset. You should never adjust
the air probe temperature offset for more than 5
American Panel Corporation is not responsible for any losses such as food spoilage resulted from
