I pulled this from the Spa Deceptionist board......
"Jim,
How can I tell if the DAIT is in summer mode? I have the temp. set at 97, when I started pump 1 the water that was sitting in the plumbing was much warmer than that. The high temp. outside today was about 90. Is there any way for me to test the fan operation? Thanks, Craig"
Now I was under the assumption that all of Conjunas customers were educated injunears etc??
