Re: Electromode thermostat
Google the word "electromode" to get a list of different applications for this type of thermostat, which is rated at about 20 amps.
They are usually used for radiant floor heat, electric baseboard, an overhead heater fan/light, etc.
Check to see if you have any of these things in your daughter's bathroom.
It's possible it was originally used to control an electric floor radiant grid that has since had a break in the wire grid under the floor & is no longer working.
