Setting temp via Siri defaults to Cooling Mode temperature limits

[gdhnz]

Asking Siri to set the temperature to 16 degrees when in heating mode tells me that it's heating to 18 degrees. The log says it's set the cooling temperature despite being in heat mode.

When I change the temp manually via the HomeKit app, it does the right thing.
