Wireless Dual Sensor Thermostat?

[larry4406]

Do they make a wireless thermostat that will measure two different areas and make comparisons and selections? For example, in AC mode the hotter of the two measurement locations is chosen to satisfy the demand while in heat mode, the colder of the two locations is chosen to satisfy demand.

I recognize that this scheme might overwhelm the other room, but I could live with it versus retrofitting a split zone system with dampers and controllers.

I have a bonus room over a garage which is on the same system as my first floor master bedroom. Currently, T-stat is in the master and is blind to what is happening in the bonus room. I have toyed with installing a second T-stat upstairs, and somehow using one for winter and one for summer.

I have a Honeywell thermostat controller that has remote sensors in the first floor, and the thermostat on the second floor. Both have to be satisfied before the unit will shut down. I have found that it works well with the air conditioning, but it is terrible during the heating season. I believe that it is a 5 wire system, and the remote sensor is a 2 wire unit. It took the tech about 3 hours to get it set up on the furnace / air conditioner, since it has a lot of control functions. It will also read the outside temperature, and the inside humidity. There are additional modules available for it also, but I don't remember exactly what they are. I do know that with the inside humidity sensor, it will control the humidity device and time it with the on off cycle of the furnace. I don't have any recollection of cost, since it was installed about 6 or 7 years ago.. Junk...
