CT-100 with 2 stage cooling

I am currently using a CT-100 with a single stage heating/cooling forced air system. The A/C is probably going to need to be replaced and I’ve been given a quote for a 2 stage system. I just want to make sure that I will still be able to use this thermostat and control all of the necessary features through alarm.com.

Thank you.

Yes, the CT100 has been discontinued and new Alarm.com accounts cannot add CT100s, but existing accounts created prior to this summer can use the existing CT100s.

Likewise the CT100 supports up to 2 stages of heat and 2 of cool. See more info in the installation manual here.
