Anyone ever worked on this water generators. I keep setting the pid to 140 Fahrenheit and it goes over the temperature and the selenium temperature valve opens up but it never brings the temperature down and it goes into 1dhi over deviation high alarm. I guess is not telling that if the selenium high temp is open it should close the 4-20ma steam valve. Thoughts ideas?
