We are not able to properly validate this code, we lack the proper
testing environment:
- instrumentation to heat/cool the cards;
- measurnment algorithms;
- stable signals for all channels.

We could set it up, but we urgently need to release the v5 version,
and this is a minor improvement.

Therefore, this feature is disabled by default.
