Abstract
Thermostats do not presently display the amount of stored heating fuel remaining. The replacement of a thermostat often requires the user to install a new backplate or goof plate because of the different size of the replacement thermostat. This invention provides a backplate or goof plate that displays the existing storage fuel level, and is for use with an existing or a replacement thermostat.
