Hello, just bought a brand new house, but didn’t get in on the process early enough to choose “smart things” as options throughout the house, so I’m starting the upgrade process. I’m also fairly new to the community so I apologize for potentially stupid questions. I promise I have searched for answers first without complete success.
So I am trying to upgrade the thermostat for the heated floors in my bathroom. Currently installed is the Aube TH115:
From what I have gather here on the forums and the rest of the interwebs, I have two main options:
Replace the thermostat with a Smartthings compatible one. Unless I am mistaken there is no dual pole 240v smartthings compatible thermostat in existence to act as a direct replacement. That leaves me with rewiring it for a single pole and hooking up a compatible thermostat, of which the selection is pretty slim. The only one I’ve found that seems viable is the Stelpro KI (STZW402WB+) Z-Wave Electric Baseboard Thermostat. I’m not entirely uncomfortable doing the rewiring, and have easy access to professional electrician help if need be.
Modify the wiring for the current thermostat to include an adequately rated in wall switch, to power the heat on and off while having the existing thermostat always on and set at whatever we elect as the “warm” temp.
For our usage, the heat will only be on for an hour or two in the morning, and possibly the same in the evening. And, although both thermostats work based on regulating ambient temp, the only real concern is my wife’s cold feet on warm tiles. Our morning schedule is never consistent, so in an ideal world, I’ll eventually figure out how to trigger this whole thing based on whoever’s alarm is set earlier or something along those lines, but that is a post for another day.
The advantages I see for the replacement thermostat are that everything is being used as it was designed and there will be control over all of the settings of the thermostat via smartthings as opposed to simple on/off. On the downside, I have to convert dual pole to single pole, it does not monitor the floor temperature (and turn off if it gets too hot), and it will cost more.
The advantages of the in wall switch are cost, the monitoring of the floor temp, and keeping the dual pole setup. Downside, the only control I have is on/off, but in reality maybe it’s not a huge deal since all I’m looking for is warm tiles twice a day. The other downside is that, as you can see in the picture, the electrical box is already pretty jam packed. I don’t have any idea how I would fit a switch in there too.
So, my questions are:
- Are there other replacement thermostats I should be considering that I have missed?
- Does dual/single pole actually matter in this comparison for any practical reason?
- Am I overlooking any big pros/cons of either setup?
- Is the monitoring of the floor temp a big deal? It would seem that if it was, it would be a feature on all radiant heat thermostats?
- If you recommend an in wall switch solution, what switch? The current thermostat is rated to 4000 watts @ 240v. I do not know the specifications of the actual heating elements in the floor.
Thanks to anyone who has managed read all the way to the end. Any thoughts or help you can offer is appreciated.
