I am having trouble setting the "Occupied Min Run Time". (This is for a ventilator when you want to run the ventilator a certain number of minutes per hour simply to exchange inside air with outside air without running A/C; having nothing to do with free cooling. My free cooling works just fine on ecobee3).
When I go to "System > Ventilator" (web), you can set "Occupied Min Run Time". There is a comment just below where you set it saying "ecobee recommends 20 min/hr".
You can change the number of minutes with a slider from 0 to 55 minutes.
If you change the number of minutes to a value larger than 20, everything works just fine.
If you try to change it to any value less than 20, it automatically switches back withing a small number of seconds (3 or so).
My problem is that I do not want to use the ventilator at all for simple air exchange, therefore I want it to bet set to ZERO and it won't let me do that. It lets me change it, but it automatically changes it back when I do!!!!
As I said, this has nothing to do with "Free Cooling". Free cooling simply says open the ventilator as the air source when the outside temperature is lower than the inside temperature. This function works fine for me as expected.
I just can't get it to stop exchanging inside air with outside air when free cooling is not applicable.
Think about it. It's 95 degrees outside, and the ecobee is forcing me to exchange 73 degree inside air with 95 degree outside air a minimum of 20 minutes per hour?????? I don't think so!!!!!!! As I said, simply running the ventilator only exchanges air without concern for outdoor temperature.
Can anybody help? I don't know what to do. I may have to completely disconnect the ventilator to keep the ecobee thermostat from overheating my house and driving my electric bill to an exorbitant level!!!!
