    Default Heated driveway

    Hawk,

    I saw your comments on the heated driveway controls pictures. There is one picture of the whole setup.



    From the right side of the window to the left is all new this year. We added a second zone. The Tekmar controller is a 664 model - which supports 2 zones. The way it is set now is very different from before. When everything is melted and the system is "in balance" and at temperature, everything gets shut down. The system goes into a kind of standby mode. No power is used and the furnace is off. When it needs to it wakes up - brings the temp back up and then sleeps again. The old controller ran the driveway pumps all the time.

    What i "need" is the ability to read all the settings and status remotely with a device that is available through a browser and is sitting on the home network. So far we have not found one to work with the Tekmar controls.

    If my son's thermostats in his house all have IP addresses and can be accessed with a browser, one would think Tekmar would have an option for such an expensive controller.

    In a past life that is now in a dim memory, I worked a bit with PLC's (programable logic controllers), mostly David Bradley. Anyway, it seems as though you could utilize them to run the controls and then just use an IP controlled relay to turn the whole mess on and off. I know that this is a breadboard sort of solution, but until the market comes out with your needs, they can be a powerful tool to get what you want.

    For turning the system on and off I use an X-10 switch. That way I can get at it remotely. What I want is the ability to look at the slab, supply, boiler, return temps, etc. for each zone.

    Suppose that's easier then shoveling it off.


    And you say you really do have one? That's funny - I've never heard of such a system, despite living in New Hampshire. How well does it work?

    They're more common than you think. Especially in places that get lots of snow. And in places like Aspen and Vail.

    Over the long run I wonder if you ever make your money back compared to paying for a plow service.
