Is it normal for a gas only setup to have the Emergency Heat light lit on the UT-3000? It hasn't been before today that I have noticed. I am on 1.17.

I wired my humidifier (non-steam, Aprilaire 400) directly to the Ultrazone panel. The thermostats will control it directly (through the UT-3000 panel, of course) in each zone. The only wires I connected were between the panel and the humidifier (H/H to C/NO, I think). I haven't tested it yet, I need ...
