ClimateMaster iGate Looks to Revolutionize Geothermal

ClimateMaster has always been a leader in manufacturing geothermal heat pumps and now they are looking to significantly up their game with the release of the ClimateMaster iGate Technology.

iGate does not come as a huge shock to me because some time ago ClimateMaster partnered with ecobee the jedi knight of smart thermostats and everyone knew something ‘neat’ would come from that.

ClimateMaster iGate is the first step it seems in a healthy relationship between ecobee and ClimateMaster.  In an official release ClimateMaster reveals some fascinating information on the new iGate system;

“The online portal notably streamlines dealers’ customer support and equipment servicing, especially in allowing them to monitor and troubleshoot a unit from the comfort of their office or home,” Hiremath said.  “In many cases, diagnostics and adjustments through the online portal can eliminate jobsite visits, particularly in flagging system issues before they become larger problems.

None of that is really new but it’s still neat to see ClimateMaster capitalize on the value of ecobee’s homeIQ and dashboard.

Now before you go thinking that all ClimateMaster is doing is throwing their name on another cool product like so many manufacturer’s do you will want to read this next bit which is really impressive;

Featuring iGate Connect™ technology, the new Trilogy 45 Q-Mode is also the first residential geothermal heat pump system to provide dealers with complete diagnostics and operating data via any Wi-Fi enabled device over the internet.  Through an online portal, dealers can access built-in measurement of all critical system operations and conditions at the past 5-faults.  More than 25 unit settings can be configured from the dealer portal, including air-flows and range of unit capacity.

What does this mean? This means that contractors can not only see reporting data on the internet they can actually adjust settings on the equipment remotely.

One word.. wow!

That is going to be a huge timesaver on commissioning equipment.

As you can see from the drawing above ClimateMaster has taken the ecobee technology and modified it to act as a Gateway between their hardware and the online ClimateMaster Dealer portal. Well done!

Should be interesting to see where this goes as other geothermal heat pump manufacturers up their game.

  1. I have a Climatemaster Trilogy system using the iGate ecobee thermostat. It does a very nice job of logging system operational parameters. The HomeIQ web based data view of operation is very helpful in tracking system operation and in fine tuning the system. Any 3 day interval of data can be viewed (past and present) allowing comparions of operation. A data download provides a csv file which can be inported into Excel. The iGate thermostat can also log 2 auxilliary temperatures, and one can be the “at the house outside temperature”. However, missing in the data download are some useful parameters shown on the thermostat Menu/System Status screens, but not logged in the data, including Trilogy ground loop water entering temperature, gpm flow; blower CFM, and iGate water temperatures in the storage tank. These would be of great use in helping to optimize the system operation.

    1. Thanks for sharing! I am a big fan of ‘ecobee’ and I am anxious to get my hands on an igate control just to see what it can actually do in comparison to other ecobee products.

      It sounds like some of the features ( fan speeds / gpm / etc ) are not yet done?

      1. Correct. Neither Climatemaster or ecobee were committing to adding those features when I asked, although ecobee said that they would give the request to the product development staff. Lets hope for more logging. Also helpful would be water tank temperture. My Trilogy has been doing a good job making most of my hot water from the geothermal source. Very occasionally it needs to use e-heat. With better knowledge of the water temperature through the HomeIQ download, it would be easier to optimize operational settings available within the thermostat. The thermostat has most operating data in it’s real time status. But the homeowner has to be at the thermostat to get the data through menu selections. Nice, but it could be better if additional parameters were logged.

  2. Richard I would be interested in knowing what data you can see on the thermostat. Are you able to see flow rates? Fan speeds? In their literature Climate Master indicated that iGate would give the contractor access to 25 different settings that they can setup and it sounds like that is not done and or the consumer has no access to it.

    As for your tank comment the irony is you can do what you want to do with an ecobee SMART with an RSM board.

    I continue to be intrigued by the iGate and do keep posting updates on how it works for you and the features it gives you.

    1. Mac, the Climatemaster branded ecobee thermostat displays the following 51 items of data through the menu:

      All of the above 51 items of data are available to the homeowner plus data on temperature settings, humidity settings, actual house temperature and outside temperature (from internet) . T1 temperature is in theory able to be installed and configured to be the active outside temperature reported in HomeIQ. Some data are useful, but some only to specialists. Only a few are reported in the HomeIQ data download from the web portal.
      I have not yet seen the HVAC contractor do a remote setup change but it is said to be possible. It’s in the “to do” list for my contractor. Will let you know how it works out.

      1. Mac, in addition the iGate thermostat that came with my Trilogy system looks to have RSM capability for hook up of two remote temperature sensors or dry contacts. I will try to set up an external remote temperature sensor and get it working. If it works, it will be reported in the downloadable data set in the HomeIQ which will be nice. Will let you know how it works out.

      2. Any type 2 10k thermistor should work so long as you have the B Value. If you struggle finding one let me know I can point you where I get mine ( disclosure: i work there lol )

      3. Thanks, Mac. I plan to use a Honeywell C7089U1006 outdoor sensor. The ecobee site indicates that the sensor had been tested OK. Would also be nice if the HomeIQ reported a second sensed temperature (I could put it on the hot water tank outlet and get HW temperature reported, but it does not seem to be a reported value yet – maybe in the future?)

        I just got a third MTU for my TED5000 which I will use to monitor electric-hot water needed by the Trilogy. Has not been much, but I want to test various settings to get a hot water situation that better satisfies my wife. Have set my HW tank temp on the thermostat (controls the Trilogy) for 125. Using HW economy at the moment which tries to use as much geothermal hot water as reasonable while keeping the house temperature from falling too much. Thinking also about measuring the hot water quantity. Then I should have all the parameters I need to fine tune the Trilogy setup. Am sure it is overkill, but I’m just a curious type. And I want to improve the accuracy of my model assumptions (below)

        I made an Excel spreadsheet which, based on hourly outside temperature (curently web based and not sensed) and my house net heat load(calibrated from past 3 years of a hybrid Oil and heat pump operation) and estimated average daily hot water need, predicts the Trilogy operation for each hour. I compare the predicted hourly kW need with measured kW usage from the TED5000. So far the predicted operation of the Trilogy produced by the geo equipment Sales consultant is matching well (within uncertainties of Hot Water consumption, internal heat generation) my expectations based on operation from Sept 9 to today. Happy about that!

      4. I used to use a TED5000 but ditched it for zigbee on my ecobee. My 12 month reporting data now includes power consumption which is very nice. ( Sorry its not available in your model )

        Also the sensor you found will 100% work I just chose for a much cheaper solution. In fact the sensor I am using is used by ClimateMaster already in the unit you have. Total cost was under $20.00. If you ask your climatemaster dealer for a freeze / hot water thermistor and use the B Value of 3972 it SHOULD work just fine.

        If it helps I can take a picture of mine and share it so you know you are getting the right thing.

      5. Hi Mac. Thanks. A picture would be helpful. The Honeywell is available on Amazon for about 24.54. Which ecobee model are you using. Would it work with the Climemaster Trilogy. Is it available as a Climatemaster offering? Would more data be available from the HomeIQ from that one? Link to information?

      6. I am using a modified ecobee smart with RSM that the general public does not have.

        That is a great price for that sensor. I will do a post this weekend on the sensor I am talking about and how to hook it up / make it work and will include photos.

        The Smart wont work on your Trilogy without rewiring and its not worth it to give up the features you do have.

    2. Hello Mac

      Today I finally got around to installing my remote temperature Sensor – Honeywell C7089 U – to my I-Gate Connect thermostat on my Trilogy 1860 system. Did the set up per the Climatemaster instructoin manual for the IGate thermostat. The install went as expected with the thermostat menu taking me through the steps of Naming the sensor, saving that, selecting Honeywell, selecting the model 7089. The thermostat had the number code needed and all seemed OK.

      But the temperature displayed said outdoor, not the name I gave it.

      Afterwards , went back through the menu through Settings to check the setup. The fields were empty and did not have what I had put in previously.


      I can go outside and place an ice cube on the sensor to see if it is displaying?

      Or despite what the Manual says, perhaps this doesn’t work as suggested?

      Any experience on this on your side.

      Many thanks.

      Richard Fisher

      1. Hey Richard unfortunately the extent of my experience with iGate is reading about it. I am well versed in ecobee but since this is an OEM product the software and hardware doesnt match what I am used to working on.

        Sorry I am not of much help.

      2. I got it to work. Very nice in that the Sensor data is displayed in a I-Gate HomeIQ widget, and in the downloadable csv data file and is also plotted vs time too.

      3. If you have any screenshots you can share I would love to see them. I am curious to see how the iGate portal looks in comparison to the regular ecobee portal.

        What sort of data you can see, what you can control, etc would be cool to know and screenshots would be great to see!

      4. I have two sensors which can be added to the thermostat. Usually they are temperature sensors. I can put one to Outside and designate it as that, one to temperature in another room and designate as “for information”, or put one in another room and designate it as “control” in which case it takes over from the temperature at the thermostat. Data is shown in the I-Gate widget for temperatures (mine is named Jacobus), and in the Home IQ plot (see yellow and Jacobus), and is also shown in the Home IQ csv download (see Jacobus) and logged every 5 minutes.  I can’t attach a picture to this. Sorry.

  3. Thanks for this post–it helped me gain some insights on the data available for the Trilogy. I was able to download my data into Tableau and combined it with power data. It’s amazing how efficient this unit is. We are off oil now and we’re on track to save at least $1500-2000 in oil this winter based on past usage.

    Email me at if you want some screenshots of the analysis or the service tool I have.

    1. Very cool patrick sounds like you have done some really cool stuff. I will drop you an email in the new year so I can see what you have done. You should also checkout the WaterFurnace symphony control for comparison it is VERY cool.
