This is probably just a Home Thermostat on steroids and it'll still lift a sack of groceries so to speak, but it'll use a lot more muscles while doing it. Since this is a 'Special Applications' thermostat, Honeywell does NOT support it and will give you NO ANSWERS to any questions you may have about it or its installation or setup.

That being said, the stat will work fine in a home it just takes a little more initial knowledge of HVAC System types, wiring and brain effort to program it. This is a Commer cial Thermostat and not really designed as a Home Thermostat. Without setting the HOLD function all settings are TEMPORARY and automatically revert to 'Energy Saving'. High Efficiency Rigid Media Dial 7625 - Ezi-Stat Evaporative Swamp Cooler Thermostat. My set of installation instructions failed to mention this and it took me several hours of internet searches and phone calls to finally have someone describe and solve the problem. Combined with the Pro-Stat programmable thermostat, the AeroCool Pro-Series will automatically and efficiently operate the equipment to best maintain your comfort level while using the least amount of energy. In order to KEEP your chosen setting the 'HOLD' button on the Touch Screen MUST be pressed. When you program the stat using the Setup Functions option you will get your AC and Heat to work BUT after setting a temperature and an hour or so elapses the temp will revert to an extreme energy saving mode i.e., 73 degree heat will revert to 58 degrees.

The user manual/installation manual 'settings' on this stat are misleading. Strange settings to get it to work - after setting up/progamming it works fine
