Hi Everyone, I have a question. I have a Honeywell Chronotherm III with a heatpump and a gas furnace for backup. The last couple of nights we have had sub-freezing weather here so the furnace has been active. I normally place the fan in the "on" position so the electronic air cleaner can do its job. The last two nights the fan has only come on when the furnace kicks in. If anyone has any ideas, I look forward to hearing them. Thanks in advance for your help.
