I'm looking to purchase a new thermostat or add a temp. controller to my current thermostat that will call my furnace blower on at a set temp range, before my furnace kicks on. The application is to distribute heat throughout the ducting in my house through the single return vent that is located in the same room as my wood stove. Let me know if anyone has ran a similar setup like this. My current thermostat has auto and on settings for the fan. Thanks
