How do you change the PV on the Zelio REG24 Temperature Controllers to display a value similar to another device?


Product Line:
Zelio Temperature Controllers with part numbers starting with REG24

Environment:
Temperature Controllers sold and used in the United States

Cause:
The temperature controller may not display the same value as another device because both of factors like thermocouple placement, calibration, drift etc.

Resolution:

Accessing the parameter
1.     Press the SEL key until P is displayed.
2.     Press the Down Arrow key until PVOF is displayed.
3.     Press the SEL key.
6.     Change the value from the default  using the Arrow keys to the offset desired.

A positive value should be selected if displayed value should be higher. A negative value should be selected if the displayed PV should be lower.
For example, a PVOF of 5 will display a PV 5 degrees higher than the device is actually sensing while a PVOF of -5 will display a PV 5 degrees lower than the device is sensing.
