This is the model I have

I only use it for heating but it can be setup with a chiller too and will work to keep your temp at the Set Value.
I only changed like two setting the SV and Hd
That will let the temp fall .2 degrees from the set value before it kicks on the heaters. The Cd would allow it to go up a certain amount from the set value before it kicked on the chiller or fans.
I don't have alarms set as I have my apex as the backup and it will text and email me
I don't know what the P7 is about and didn't change it either.
