I purchased the Honeywell Wi-Fi VisionPro 8000 thermostat back in June, 2015 and this week, the thermostat failed. Heat Depot came by my house and determined the failed thermostat needed to be replaced. The 5 year limited warranty did not covered the failed thermostat. They were out the next day and replaced the unit quickly and helped program the new replacement thermostat. Overall, they did a great job getting my furnace back running again.
