5 out of 5 stars review
Just what i needed
Sad i had to buy this to keep an adult from changing the thermostat...works perfect...he can't change the temperature anymore. Now if he keeps up with the fan all night I will be looking for a fuse box lock next and turn off the power in his room

Does job intend for. Can sleep better at night, people can't turn heat and air up and down.
