Johnson Controls T-4756-2145 Plastic Cover

The Johnson Controls T-4756-2145 Plastic Cover is a high-durability replacement faceplate designed specifically for T-4000 Series Pneumatic Room Thermostats. This beige, vertically-mounted cover is engineered for dual-temperature applications, featuring 2 setpoint windows to allow for clear visibility of heating and cooling dials. As a veteran-grade HVAC pneumatic accessory, it provides a clean, professional finish for T-4756 heating-cooling thermostats and compatible T-4054 models without the need for an integrated thermometer. The impact-resistant plastic construction ensures long-term protection of internal sensitive bimetal elements against dust and debris in commercial environments. This dual-window thermostat cover is essential for maintaining the integrity of pneumatic control systems that utilize high-volume output thermostats for automatic changeover between direct and reverse actions. Its vertical orientation and standardized mounting clips ensure a secure fit for rapid field replacement during routine HVAC maintenance or system upgrades.
