Abstract
Abstract A locked thermostat box for wall mounted thermostats including a cylindrical lock which cannot be opened except by the proper key. The cover for the box is a portion of the box itself and is easily removed after unlocking with the key providing access to the thermostat for adjustment. Basically the box is in two sections, one of which is mounted with the thermostat on the wall and the other which is the cover previously mentioned. The cover includes four sides of the box which are bent from a piece of sheet metal and the wall mounted portion of the box has two sides bent from a piece of sheet metal with marginal channels formed by turning-in a small portion of the edges to receive the edges of the cover.
