Check back

with me in a few months. I am with a company developing controllers that will be very simple to use, internet monitoring and parameter settings, and will be able to replace multiple controllers with just one unit. We are still working on the programming. But I can say one thing, you will love it! You can send me an email with your contact info so I can send you the finalized information.

Used on one job recently. Simple. In expensive. Client logs onto the web vis their site.

What happens when the internet company that developed the system is no longer in business? - DF

bought a company called Innovex in Dec. All kinds of controls that are web accessible. I would trust Taco

Controls are not developed by internet companies...

Control systems, at least commerical ones such as Johnson, TAG, Automated Logic, Delta, Andover, Siemans, etc, operate on BacNet or LonWorks as the communications backbone and can be accessed via any internet service. Each piece of equipment has an IP Address assigned to it just like our computers.

The hardware and certain software functions are proprietary, but all are designed to allow points (room temp, ouside air temp, supply/return temps, digital and analog outputs, etc.) access via BacNet and/or LonWorks.

The controllers basically operate "stand-alone" (i.e., they have an intranet) and the PC via the internet is used as an interface device for display of system graphics and manipulation of points (changing a setpoint) by the user. To access a building site from your PC you just enter the assigned IP address and then log-on with a user name and password (that have various security levels).

It is my bet that systems designed for residential use would follow the same architecture.

Tekmar my friends-TN4 a modular control approach that can combine hot water heat and cooling-as well as internet access thru a web browser-relatively inexpensive when compared to home automation systems-

We're working on our 7th Uponor Network Control project. If your looking to control a complex HVAC system, Uponor's system is extremely flexible, and provides you with internet access to every component in the system.

I built a remote monitering control for a the heating system in a large building last Febuary. I used a PLC with a Touchscreen computer because the controls were really complicated. We had 4 oil boilers, two electric boilers, three radiant zones, 1 baseboard zone, 5 pumps, 2 D.H.W. heat exchangers, outdoor reset, offpeak electrical control of the electric boilers etc... I had to program the PLC and the touchscreen for this specific application.

With the touchscreen computer, I have access to the control program over the internet. I can monitor and make changes to the heating system directly from my desk. The building is about 5 miles away. There is even an option for sending out an alarm email to you email account or on you cell phone when there is a problem.

The PLC, programming software, and Touchscreen are all from EZAutomation. Built in USA. Quite impressive.
You can check them out at: http://flash.ezautomation.net/

If you want more info, I could put some pics of the different screens on the touchscreen. There are several nice functions that can be added to the screens.

Here is a quick description of the product operation without getting in too much detail.

The iWorX control system architecture consists of an LCI2 (Local Control Interface) at the top and then all the radiant and HVAC controls below. The LCI2 communicates to the controllers via a LonWorks network and the LCI2 can be communicated to over the World Wide Web. There is typically an LCI2 at each installation since this is currently what is used by the installer to configure each controller and the building owner to monitor the system. The controllers are pre-programmed with typical applications in mind and this eliminates the installer from having to know a programming language and also eliminates network tools/software. Basically, the installer configures the controller’s settings to match the application. The LCI2 can be configured to send email alarms so that problems are detected before there is a crisis. Once notified of an alarm the service tech can connect to the LCI2 over the www and can evaluate the situation prior to making the service call.

Let me know if you need any additional information.

What kind of sensors

did you use for sensing flow, pressure, temp., alarms, etc.

Richard_6

Joe, do you have anyone that can make the Innovex system at our office in Westwood, MA work? Both Tom Polansky and Roger Michaud have tried and can't seem to. It has a bunch of error messages all the time. We clear them and get frustrated. I sent Johnny White an email with no response. We were the reps for Innovex before you guys and remain frustrated with getting this stuff to work right without error messages daily.
Roger was big on promises; short on support. With Taco on board, maybe we can get it fixed. Please email me off line to coordinate.

Help! Richard

Go with a crestron system.Has all the sensors,resets, floor max temps,and internet controls.

Luc

For the temperature sensors I used some 100ohm platinum RTD(PT100)from Greystone.

For the current sensors of each electrical phase, I used a 4-20mA current sensor from Greystone.

Hope this helps,
Luc

Richard T,
I don't recall your e-mail, and it is unlike me not to respond, so I apologize.
I'll be on this one as of now.
I will say that we are working tirelessly to perfect the product before a major release.
Can you give me a phone number??
Johnny White

Joe Mattiello

I'm waiting to hear back on your question. I'll be in touch. It would easier, if you provide an email, or telephone number.

Response

Richard, The last issue I was aware of was a controller problem that was resolved with an RMA this past January. If you are having any issues please contact me and I will be more than happy to help you and your staff resolve them. I will be in RI next week and can visit your office to help, just give me a call. I left you a voice mail message as well as an email with my contact info.

Sincerely,

Tom Polansky
