家里控制热气的那个装置,这几天在屏幕上总是一闪一闪的显示"filt",请问是怎么回事啊?请知道的朋友赐教,谢谢.

Read the user guide (manual) for controll and follow the instructions to change filter and re-set the timer. If yours is Honeywell, do the following: (1) change the filter of your furnace; (2) press the letter "i" until you see days on the screen of the control (you should see 0 days here); (3) press the upward tringle under the word "time" until to "90" days.

是Honeywell的吗？如果是，按楼上说的设置一下。
