      My current thermostat is 1 foot away from the furnace located on the first floor of my house. Is this fancy pants device something I can use to basically disable that existing thermo and place this new thermo on the 2nd floor of my house?

        You should have no problem doing that. As long as you don't touch (change
        anything) on your wired/current thermostat the wireless one will control
        everything. If you do touch/change the wired/current one, all you have to
        do is to push any button on the wireless one and it will switch back.
        Assuming you will also be purchasing and installing the corresponding wired
        thermostat (since that is that the receiver plugs into), keep in mind the
        T1800 (and I assume the T1900) requires 5 wires not the normal 3 or 4.
        There is a 5 wire accessory if you don't have 5 wires. In my case I had 5
        wires but the fifth wasn't connected at the furnace, I connected it and have
        had no problems. I have no idea how long batteries last in this because I
        purchased the optional power supply and leave it plugged in sitting on my
        night stand. Nothing better than being able to adjust the temperature
        without getting out of bed. I've had mine about 2 years now with no

      I have 3 units for a church sanctuary I would like to use these in. If I set them on different frequencies, can they be used in the same room?

        The T1119RF is an 'Add-A-Wireless Thermostat' accessory that allows you to add one wireless thermostat to a T1800 or T1900 thermostat. If you have multiple T1800 or T1900 thermostats on a jobsite, and you want all of them to have the T1119RF accessory, there are house codes that allow them to be differentiated.
