检查一下温度控制。上面有auto或者on。

你难道不知道家里的Thermostat在哪里吗？

I did check Thermostat. It was set "Auto". When the temperature in the room is 25 degree, I kept lower the control of furnace to 10 degree just for testing . The fan still on, it is on day and night never stop. However, the temperature in the room stay as I have set by the Thermostat.

看一下你的Thermostat显示屏上有没有显示出fan 的字样，如果有，按一下Thermostat控制器上fan字样，显示屏上的fan字样就会消失，fan就会在 furnace is off的状态下停止工作。

如果风扇开关／选项没有选择它一直循环风，那是控制系统问题。
有人家一年四季风扇转着循环室内温度湿度的。

Do you have HRV? My house is like that, the fan is always on, but I vaguely remember one time my husband turned it off from the basement. The fan is running for air exchange and to adjust the huminity of the house, something like that.

我猜你的房子有HRV，如果你把HRV也Turn Off，炉子的风机就会按照你说的那样运转了。只要HRV在运转的时候，炉子的风机总是在运转的。

I am not sure what HRV stands for. There is no air conditioning in this house. Is HRV related to Air Conditioner. Anyways, I will check the instruction book(a very confusing book for me) again and try to do something according to your hints.

I will let you know how it goes. Thanks everybody.

HRV stands for Heat Recovery Ventilator

把湿度调节关到０， 注意是湿度 不是温度
