Description
The Johnson Controls T-4002-2123 Cover (discontinued) is a Johnson Controls thermostat cover that provides an opportunity to change the appearance of the thermostat and possibly improve its performance. This cover has a shiny and smooth nickel plating that will blend with different interior designs. This cover fits over the current horizontal-mount thermostat cover, which you probably have from Johnson Controls’ T-4000 Series or possibly older models. The open-face design provides easy visibility of the thermostat’s display and, at the same time, shields it from dust and minor wear.
