<p>I attempted to control the Helium level with EV8512S in the DBX, but this valve is too big (Cv=3) so I went back to using EV8611JT but put in a PID to reduce the Heater power when the valve is off its minimum. I'll keep an eye on it over the holiday and see if we can get the system stably operating w/o any electric heat.</p>
