Thermostat Remotes are a great way to set it and forget it. Enter your desired room temperature and the remote will turn your gas fireplace, logs or stove on and off to keep the desired temperature within 2°. The transmitters have an easy to hold design that fits nicely in anyone's hand. They have LCD displays for room and thermostat temperature. Although there are units that need to be plugged into a 110 V outlet, most are operated with batteries.
Another popular thermostat remote is a wall unit - nothing to misplace or have the kids or dog run off with. This remote looks very much like your wall thermostat for your furnace.
