Watching it decide — which is what `commands: false` is for — caught two
things a type check never would.
It wanted to cool the house to 21 degrees in August. The comfort band is what
*heating* aims at; the reference cooled above 26 and at night above 24.5, and
this port had collapsed the two into one number. A compressor running every
summer afternoon to reach a heating setpoint is the most expensive kind of
correct-looking bug.
And it was willing to heat while the pellet stove was doing the same job. The
reference only ever let the heat pump heat when the stove reported itself
faulty, which is the right way round: the stove is what heats this house and
the pump is what covers for it.
Both tables now have a check behind them, along with the boilers' — the three
places in the house where a wrong threshold is a bill rather than a mistake.
