Whole house fan needs virtual thermostat


#41

I got the chart from cattle stress temperature because there is no human chart and it looked good as a reference.
I think @WCmore is correct it is feel like temperature.

To answer you previous question

All white blocks regaudless if theres a number in it should be Fan On

The second part of the question is

I want the virtual thermostat to catch the lower temps below 68 degrees.

At your request, I created a formula that essentially cuts a diagonal path across all possible numbers.

temp

When the current data is to the upper left of the line, the fan turns ON.
When the data is to the lower right of the line, the fan turns OFF.
When the temp is less than 68, or greater than 79, the fan turns OFF

Here is a precise breakdown:

     Temp & Humidity
  FanOn      |    FanOff
¯¯¯¯¯¯¯¯¯¯¯¯¯|¯¯¯¯¯¯¯¯¯¯¯¯¯¯
             |  80° or higher
79° & 0%     |  79° &  1-100%
78° & 0- 7%  |  78° &  8-100%
77° & 0-14%  |  77° & 15-100%
76° & 0-21%  |  76° & 22-100%
75° & 0-28%  |  75° & 29-100%
74° & 0-35%  |  74° & 36-100%
73° & 0-42%  |  73° & 43-100%
72° & 0-49%  |  72° & 50-100%
71° & 0-56%  |  71° & 57-100%
70° & 0-63%  |  70° & 64-100%
69° & 0-70%  |  69° & 71-100%
68° & 0-77%  |  68° & 78-100%
             |  67° or lower

… and of course, the highly anticipated piston.

I added a bunch of comments to help you make sense of it all…

When importing this, make sure you pause any other pistons that are controlling the fan when testing this new piston. (It updates, and corrects the fan every 15 minutes)

Thanks,
This is everything I ever wanted and more.
I am beginning to like WebCorE.

It surely is a remarkable tool, and one that I can see myself using for many years to come
