I looked at several for sale on the web and they don't say much about how they work and or what components go where. I even looked at the instruction manual on how to install one in particular. It showed a typical t-stat wiring diagram and discussed its function but was dead silent on how it would operate from a remotely mounted sensor.
I'm hoping someone here has installed one and thinks it would work in my situation.

Essential Info
Did you ever wish you could turn up the heat without getting out of your warm cozy bed? Or that you could turn down the air conditioning from your living room chair? Or put the thermostat in a newborn baby's room to keep the temperature exactly right? If you wish to be able to move the thermostat, put it by your bedside at night, or even control your heating and air conditioning system from two different places, such as upstairs and downstairs, then the Venstar Wireless Thermostat is for you.
Here's how it works: Remove your old wall thermostat, replace it with the Venstar receiver and then remotely control the temperature anywhere in your house with the Venstar thermostat. Add additional wireless thermostats around your house (up to 4) and have instant access to temperature control no matter where you are.
