I have made a piston that
if temp outside is equal or lesser than 78 AND temp inside is equal or greater 74
Then turn on hvac fan.
Got it…
Now how do I get it to turn off once the inside temp reaches 70 or lower?
Thanks for any help
(Yes I know my temps are weird… The intake vent is on the cool side of the house in the evening so it is actually a bit cooler than local weather reports.
Just make another if statement that has the condition
IF temp is <70
Then turn off HVAC
You can do it in the same piston
Never got a notification of your reply.
Thanks that did that trick… Then I had a weather change which brought up a new problem.
I have the piston built but now I need to add a only run between these times. E.g. only operate piston between 6pm and 7am everyday.
I see the time and date variable setting but they all include a date. The closest there is the one for noon to midnight or sunset to sunrise times. The sun times are close but I lose hours prior to sunset when I can save the most on cooling.
What about if you had a time condition to your If statement. If time is between 6pm and 7am AND outside temp is <=78 AND inside temp is >=74
