R

Hi neighbors, this is definitely kinda silly but I was hoping someone could recommend what my thermostat should be at and what mode to have it on now that we’re entering winter! I like my place to be warm and comfortable but not hot and hopefully keep my bill not too high! Thank you in advance.

L
Resident

Not silly! I was wondering the same thing.. please help jaja

H
Resident

I put mine on heat heat mode at 73 due to the “auto” function (in my apartment) does not seem to work. I do have a tendency to turn off my thermostat when I go to work and when I come back 9 hours later my apt is still warm. Hope this helps.
