We have a Climatemaster Tranquility 2 stage with elect aux heat, we have been using Climatemaster Thermostat ATP32U03 since the Geo was installed Oct 2013. I noticed that when we lose power the thermostat does not have a memory to turn the GEO back on. I talked with Climatemaster tech support and they told me they rely on Capacitor built in the thermostat for memory setting, with about 2 hours of memory. This has been OK in the past but, we are planning to be gone for 2 to 3 months at a time in the future , so this thermostat will not work for us now. Looking for what would be the best replacement and I do think I would like the system that can be monitor from a computer or cell. I say "think" because I don't want it if it is more trouble then its worth.
