Don't know who makes the board for that brand but they sure do a good job. Rheem & ICP used Ranco for demand defrost, the DDL wasn't the most reliable thing. ICP went back to timed, Rheem stayed with it. Overall I think they got the bugs out of it. The new Ranco boards with diagnostics and lockouts had a few bugs but failures are pretty rare.
Then there's the board Lennox & Allied used. On Air Ease, they only have a low pressure switch, the HP terminals are jumped. Yet we keep going out to find units locked out on high pressure. Finally learned from the factory that the board was programmed wrong. The indicator LEDs reported the opposite of what happened
Ought to hear a neighborhood full of cheap builder heat pumps on a cold night. Those timed boards go in & out constantly. Can get pretty noisy especially with a scroll screaming.
