Description
Product Summary
The Johnson Controls T-4506-203 is a thermostat from Johnson Controls, described by the manufacturer as: DA pneumatic dual temperature horizontal mount thermostat without indexing switch. It replaces T-4502-203 (replace Cover Also).
A thermostat reads the room temperature and tells the heating and cooling equipment when to run. Matching the thermostat to the system's stages, heat pump or conventional setup and power source is the key to a correct replacement. Replace a thermostat that reads the wrong temperature, will not call for heat or cooling, has a blank display or does not support the equipment's stages.
