Daikin central air conditioning shows that there is no hot and cold option, and the main control board cannot be found. Why?

Because when the main control board and the sub-control board can't switch modes, it is usually because there is something wrong with the dialing code of the outdoor unit, so that the outdoor unit can't be connected to the indoor unit.

Solution: You need to open the outdoor unit shell and search on the control panel. Daikin air conditioner has the function of automatically searching the address code, so that the outdoor unit can find the indoor unit.
