Inquiry (采购产品): Model # XL411 Just bought a house equipped with one of your thermostats, model# XL411. Previous owners did not leave a manual. Problem is the display is flashing "FL" over and over although the thermostat and furnace seem to be operating properly.Question 1- what does that mean? Question 2- can you send me an owner's manual/direct me how to obtain one?
