You can easily do this by using a wireless thermostat model #T1100RF. You replace the thermostat that controls the area of the house that the room you want at the perfect temp is in with a wireless thermostat usually the wired thermostat will be in a hall way. The base unit (receiver) of the wireless thermostat mode # T1100REC goes right where the old thermostat was located and wires just like a wired thermostat. However now you have another device which is the wireless thermostat model #T1100RF which includes the temp sensor. Wherever you place the thermostat it will keep that room at the desired temperature. All other rooms on the same HVAC system will have different temperatures based on how much air flow and air-condition load they have. The wireless thermostat can be placed anywhere on a night stand, screwed to a wall etc. Of course since the thermostat is completely portable the home owner can move the thermostat to different rooms and whichever room they put the thermostat will be conditioned to their desired temp. They can have up to 4 thermostats on one receiver, so they could put one thermostat in a room upstairs (say a bed room) and another in the living room down stairs. The last thermostat they touch is the controlling thermostat so they could touch the thermostat upstairs when they go to bed and keep the perfect temp for sleeping and then when they go downstairs in the morning touch the living room thermostat so they keep the perfect temp in the living room or even put another thermostat or move the living room thermostat to the kitchen so they have the perfect temp when they cook.
