A:AnswerHi Needinfo, thank you for your question. This thermostat works with cool only systems. We will be happy to help verifying the compatibility of this thermostat and your system. We need to know how many total wires you have and which terminals are being used on your current thermostat. Feel free to contact our tech support team at (800) 633-3991. - Maria
A:AnswerHi ArnieTalks, thank you for your question. You can use this thermostat and the smart room sensors to control the temperature. When you adjust the temperature in one room, it will impact the temperature in the rest of your home. For example, if your basement is regularly 4 degrees cooler than your bedroom, it will continue to be slightly cooler as you adjust the temperature to meet your bedroom preferences. If the bedroom and the basement are both selected as priority rooms, the thermostat will average the temperature of those two rooms, and your basement will still be cooler than your bedroom. The T10 model requires an HVAC contractor for installation and configuration. - Maria
