We have the old knob style controls for the cruisair temp and fan. Kinda of a pain to dial in the temp as often too hot or freezing. Fans never shutoff, but the cooling water pump will when temp is reached. Can you add household style thermostats? Are there 3rd party options. The cruisair options are costly and don't fit.
