Non-zero values for offset on GRV-ITR-12 channels configured as thermistor inputs are not saved correctly


Applies To:

Firmware for GRV-ITR-12

Versions Affected:

1.3a to 1.4d

Resolved In Version:

1.4e


Symptoms:

For channels on a GRV-ITR-12 module configured as thermistor inputs, on occasion, if you specify a non-zero value for the offset, the value is not correctly. The saved value will typically be zero or a very small value like 5.60519386e-45.

  • If you configure the channel through groov Manage, after you save the configuration with the non-zero value for offset, then you reopen the Configuration page, you'll notice that the value you specified for offset was not saved correctly. 
  • If you configure the channel through PAC Control:
    • The strategy will download and run without reporting any errors regarding the configuration of the channel.
    • When you view the channel through the Inspect window, PAC Control implies that the offset value was set correctly. However, if you view the offset value through the memory map or through groov Manage, you'll see that the non-zero value was not set correctly.

Resolution:
