    Buying a TR40

    Does anyone know if the TR40 comes with both the Wall Display Unit (WDU) and the Thermostat Control Unit (TCU) included?

    Also, can the TCU be hooked up directly a serial port on the computer running homeseer?

    Thanks all!

    Yes - the TR40 comes with both the Wall Display Unit (WDU) and the Thermostat Control Unit (TCU) included - haven't tried to hook it up directly to a computer running HS

        They are fine units.

        Watch out, there are RS-232 models and RS-485 models.

        RS-232 will attach to the COM port of your computer.

        RS-485 will attach to the COM port but only after installing an RS-485 to RS-232 adapter. They are inexpensive on eBay and such.

          All of the RCS serial thermostats are designed with an RS485 interface. They don't make RS232 native models. However, they do make an RS485-RS232 hub that they recommend for the conversion:

            I have the z-wave TZ40 which is zwave (using an adapter that connects to the RS485 port on the control unit), but I'm using it with the RS485 interface instead. There were a few features that I wanted to use such as messages and setting the outside temperature that didn't work with the z-wave interface.

            If anyone is ever looking to convert their RS485 thermostat to zwave, PM me and maybe you could get some use out of this little converter box.

            Great thermostat!!

              Mine has the little sticker on the control box like the one in your photo but it says TR40 RS232 Model and I'm pretty sure I wired my serial cable right the board.

              But I will concede I can't find them for sale anywhere.

              I guess you did say they don't make instead of they have never made...

                correct. The unit you have dates back to 2003. The only units made now are RS485 native.

                  Are the older hardware versions completely upgradable with firmware to equal the newer shipped models?

                    I bought 2 TR40s on BestBuy auction site and have to admit, I didn't give a lot of thought to the RS-485 part. Has anyone tried a USB to RS-485 converter like these?

                      I seriously doubt that they are upgradeable. I had an RCS zone controller that had a firmware defect. The only way to fix it was to swap out the controller with a replacement.

                          I was too, for a while. There were a few things I couldn't do that I wanted to like set the outside temperature on the wall unit via homeseer.

                          I contacted RCS and they said talk to ZenSys, who said talk to RCS, who said talk to ZenSys, who said it's not supported. It may have changed since then, and if so I'd switch back to zwave...

                          If not, I'd be happy to sell that zwave->rs485 adapter to someone who doesn't care about that feature.

                          ZWBT-485 for sale? Anyone know if you can set outside temperature via zwave->rs-485?

                            I agree. many things need to be done with both the RCS and HS ends
                            RCS is working some of the issues, you may want to contact them again
                            It is the most reliable interface I have
