On another note, I thought of a way for Digi-Cool DRSA-1100 and 1600 owners to mod their units to do SH and SC with 2 probes.
Those models only support one temperature prob, so normally the probe needs to be moved from one line to the other when switching between SH and SC.
Do a mod to plug 2 probes in, like I did, but wire them to a DPDT switch mounted where the existing prob connection port is.
To switch between measuring SH and SC, you just hit the mode button to change to calculating SH or SC, and flip the switch to use the appropriate probe.
If more government is the answer, then it's a really stupid question.
