I saw the press release of Lagotek's products and got excited by what the company president calls Active Room Control for HVAC. I have been looking into it for a while. I have a house built in 1988 without dampers for AC so no zones. Thermostat is in the central living area with bedrooms on either side (master and baby's room). The Lagotek system claims to be able to adjust temp based on room people are in with temperature averaging done at night for the master and baby room.
