Scott,
Tell us more about your set-up.. Do you have a Pool with a Spa or just a Pool? Pentair has several versions of the EasyTouch, so it would be best to get the one that fits your needs.
What Pentair pump did you get? Is your pool a saltwater pool or were you planning on making it a saltwater pool?
You will need to add ScreenLogic2 in order to control your pool remotely.
With regards to your heater question... With ScreenLogic, you can sit inside and monitor your Pool/Spa status on your PC, tablet, or phone. You can turn your heater on or off and set the temperature you want all with a couple of icon clicks.
Thanks for posting and good luck with your upgrade.
