Hi!
I’m planning to install TempZone in my bathrooms – on the first floor and in the basement.Bathrooms have only one 120V line from the panel – which powers vanity lights and wall outlets there … to get a new dedicated line from the panel would require almost a full house demolition…
Both systems will consist of SmartStat and 10-15B-120T roll.
Any troubles you can foresee in this situation?
Thanks,
Sergei

Sergei,

We always suggest that systems be on a dedicated breaker. The reason for this is that it makes the possible troubleshooting of systems easier should that occur and also keeps load down on the circuit and saves systems from overloading in that fashion. Now, a 10 foot roll only utilizes 1.88 Amps meaning that both rolls for both systems would utilize 3.76 Amps in total which in the grand scheme of household systems is barely anything.
The only other problem I would imagine could arise would be when the breaker comes into play. Many breakers nowadays are GFI (Ground Fault Interruptor) active meaning they have a GFI already built into them. NEC code these days requires a GFI active breaker for a bathroom or GFI outlets to be installed in the bathroom or a combination of both. The thermostats for our systems already have built in GFI’s and GFI’s on the same circuit do not get along. The GFI that is first in the line will normally trip off the secondary almost every time creating problems. This would mean that your shared breaker would need to be a standard breaker, non-GFI active and depending on code, may not be advisable. It may be best to also check with a local electrician on this subject just to verify that you could surpass this obstacle.
Hopefully that will help you in your endeavor! If you should need any other questions answered, please let us know!
Thank you Sergei!

Thanks, Keith!
The breaker on the line is not GFI for sure, but outlets are with GFI … which means that thermostat’s GFI and outlets’ GFI will be in parallel not in sequence …
Should be working …
Thanks,
Sergei
