I have an issue regarding the time delay on the indoor fan motor on a call for heat. I have the fan commanded on all the time, but when I call for heat, the fan turns off and goes through it's time delay (heat exchanger warm-up period). I have 23 York rtu's at this building, albeit different sizes, and this is the only unit that this is happening on. Anyone know if the logic can be programmed in the UCB?
Thanks in advance.
