I believe we will want BC control during ISO UF state.

Remove blank line and comment saying we're not doing anything (because now we're doing something).

isBalChamberSwitchingOffRequested is an output.

Should we set the other switch to FALSE, just in case?

Add TODO to comment.

Put () around the 2 conditions

Ya , I forgot the coding guide line .

Use explicit BOOL conditions (e.g. TRUE == isFreshDialysatePressureInRange).

I prefer to be explicit on BOOL conditions like this (e.g. TRUE == isFreshDialysatePressureInRange).

Remove extra blank line.

I don't think we need to check test config for variable initialization.

Since fill and drain is a single time request and it is not a frequent request similar to supply during dialysate generation. I removed and now run as idle

To make it exclusive operation. no previous request should be pending when a new operation is requested. So only one state machine is running at a time. otherwise, while chamber fill is in progress, anyone can request drain and both requests will be handled. even through new code run only one state machine at a time, this will ensure that only one request is submitted to drybicart

This was a concern reported by Sean and proposed for restructuring into a single state machine.
