Whenever the power resumes after an outage (e.g. thunder storm), the thermostat
requires the "filter media", "humidifier", and other settings to be confirmed
before the heat resumes.
Thus, if the house is unattended in the winter, the heat never comes back on
after a power glitch because the thermostat just sits there waiting for someone
to answer some questions. The risk is that the pipes will freeze.
Is this normal for that type of system?
