Floor Heating Tstat, Hi-Volt thats Integratable
Hi All,
Anyone have a solution (particularly for Retrofit) for Hi-Volt (120-240v) floor-heating TStat?
I've tried the NuHeat units, but with the *Cloud-based Integration* its just not reliable, IMO. I have two sites that I cannot keep online and am looking to replace them with something that communicates locally.
TIA!! |
Also, if I remember correctly, a Crestron TSTAT could be used for floor heating. There are a bunch on eBay along with slab sensors. Also on eBay I saw a Crestron DIN-1TSTAT8 8-Zone Radiant Heat Thermostat Hope this helps Jay On 11/13/2024 12:40 PM, stefuel2 via

With new construction and some retrofit, you definitely could use 'standard' TStats. But if you have existing Hi-Volt units, it can be a bear to retro an LV TStat as you need not only a 'Low-to-High volt' relay but also a transformer to power the Stat... It gets pretty ugly even in a 2-gang box, and a lot of these units are in a 1-gang box. It's still possible but not nice. The NuHeat units would be great if their integration didn't suck!!
Horizon supports 10k Ohm sensors now so that could be an Replacement option when install allows, though it would likely need to be remoted, as it is horizontal orientation and has the in-wall 'bump' that would definitely eliminate fitting in a gang box with a Tx and relay...
Just hoping for a decent alternative... (I should always be prepared for disappointment...) |
I'm at the point where giving up is the only option as well.
Regarding NuHeat, I went back and forth with them and Intersystem Controls for over a year to finally get it working.
Finally, about 2 months ago, Intersystem emailed me an updated module that "fixed" the controls a bit.
My system would get authentication and seemed fine, but none of the commands would work except for "Get Info".
With the new module, it has been working consistently for about 2 months.
It's worth mentioning that you should somewhat ignore the example program with regards to how it handles analog temperatures.
It is structured to just throw away the remainder when converting to a 2-digit temp for display on an interface.
My clients don't like it when the thermostat reads 79 and the Crestron panel reads 78 because 78.8 isn't properly rounded up.
I just did the rounding the proper method.
Regarding other options, I'm looking into options using Hubitat (Thanks Jay!!!).
Sinope makes 120/208/240V in-floor heating thermostats that are compatible with Hubitat.
So, fingers crossed ... that might be the best option.
Otherwise, maybe making pizza for a living is still on the table! |
Thanks Brian. After my recent article on integrating home assistant (HA) with Crestron (https://restechtoday.com/my-experience-integrating-crestron-and-home-assistant/), you might check if there is an HV floor heating thermostat compatible with that platform. While I really like the Hubitat, and it has proven to be a very reliable platform, HA integrates with many more products than the Hubitat does. I'm running both in my house now and haven't had any reliability
issues with either one. I will preface that with the fact I've
been running the Hubitat since 2020 and only started working with
HA this past summer. Hope this helps Jay On 11/14/2024 9:31 AM, Brian Matson via

Just use a contactor with the appropriate voltage on the coil. Then you can use any thermostat

Thanks, Grant Dunn |
As always, Thanks to Brian and Jay...
I hope that we can do some testing for a good floor heat TStat and find a decent solution for these kinds of things. Hubitat and Home Assistant increasingly seem to be the way we will need to interface to things that we never (in the past) would have considered worthy of using but now may be our only solutions!!
And especially a big shout out to Jay who has singularly led the charge in developing and testing these things.
I highly recommend his resources and think that others should try them and send him some $$$!!...:) |
Thanks Chris. I've just been a firm believer for a long time that there are
great IoT devices out there, that have some incredible
functionality, and can really enhance a smart home. And, Just
because Crestron wants everything in a smart home to be purchased
from them, that shouldn't be a barrier to adoption. Even if the
lack of margins on these devices keep them from being used on many
customer projects, Crestron programmers, with a system in their
own homes, can save a boatload of money compared to Crestron
products. And, once programmers become comfortable with these
devices in their own home, they can be used in limited ways in
customer systems to add special functionality. That being said I still think Crestron makes some great products. I have CLW light switches throughout my home and the ability to customize the button configurations and engrave them is still a significant differentiator when compared to off the shelf smart switches. I also think that Crestron will eventually come out with a Matter gateway for Crestron systems. In this way they can monetize dealers adding consumer IoT devices into a Crestron system. For those that want to dip their toe into the waters of consumer IoT devices, I would recommend looking at the Aqara FP2 presence sensor. The product is a game changer when it comes to what you can do wrt presence sensing in a room. Its use of mmWave radar allows you to setup zones in a room and detect when people are in a specific zone, not just in the room. You can create all kinds of automations based around that knowledge. For example, you could create a detection zone in front of a gas fireplace and shut the fireplace down when someone approaches it. This could save a toddler from significant burns if they are attracted by the flames of the fireplace when someone isn't watching. You could also setup detection zones on either side of a bed and dimly light pathway lights to the bathroom if someone gets up at night. But, the lights won't get turned on if there is movement in the bed itself. Finally, the FP2 is so sensitive it can detect the movement of someone breathing while they are asleep. So, you can truly know if a room is occupied or not. All of this is impossible with a standard presence/motion detector. The only downside to the FP2 is that it isn't battery powered, it has to be wired to an outlet. Here is an article I wrote on it: https://restechtoday.com/occupancy-sensing-with-the-aqara-fp2-presence-sensor/ You can find all the drivers I've written, including the
Crestron-Hubitat driver on my github: https://github.com/jbasen/ Thanks again Jay On 11/15/2024 6:23 AM, ckangis via

I'm working in a house that has existing Somfy MyQ shades and we've added some Crestron shades in other rooms. Crestron shades are head and shoulders better than the Somfy (or HD) units in terms of quietness, control capabilities, Feedback (Somfy has none) and RF range this install has a LinkProZ that is 50' away from one room of shades and its highly unreliable. I'll spend more time solving the Comms issue than its worth...
Device idiosyncrasies and the work-arounds for them are where I spend most of my time...
Thanks for mentioning the Aqara Presence sensors, I'm excited about the technology, and also hoping that Aqara and others will find a way to build units that look nicer for the kinds of homes that we deal with...:) |
No arguments on anything you are saying. Unless you are a
programmer, looking to automate existing shades on a budget that
fits your salary, you are not going to to use SwitchBot products
for shade automation. On the other hand, if the customer comes to
you and says, we have this awesome espresso machine. We just love
the coffee it makes. Can you automate it so when my alarm clock
goes off in the morning it automatically makes coffee? Now your
response can be - "Sure, I have this neat little device called a
SwitchBot Bot. We can use that to automate your espresso
machine. The only downside is that periodically you'll have to
change the battery." Customer is thrilled. For me, this isn't about replacing what Crestron can do. It is about doing things that Crestron can't do. I've only been on one project that didn't have a budget. There were over 200 Crestron shades in that house. Every other Crestron system, no matter how big had a budget and there were tradeoffs made in functionality vs cost. It is nice to have the option of an IoT equivalent to a Crestron product to save a buck. It may not be as nice, but it will function fine and allow money to be spent on areas where having a Crestron product really makes a difference. Does the customer care that the Somfy shades aren't as nice? The
Somfy shades may be perfectly adequate for them even though the
Crestron shades are much better. One last thing. I believe that the Aqara FP2 can be mounted in
the center of a ceiling where it would pretty much be invisible.

Thanks, Jay. Agreed!!
MQSACK, That's a good suggestion, however it is similar to Crestron Din unit.
What I'm really looking for is an integratable Hi-Voltage wall mount TStat that can replace an existing unit already hard-wired in the wall.
Often we cannot easily re-wire the Hi-Volt to accommodate Low-to-High voltage interface with Crestron or other stats...
Thanks for all the responses!
