This Resideo adapter is designed to provide a common wire (C-Wire) for HVAC systems that lack this component. The adapter, also known as a 'C-Wire Adapter', is used to supply constant 24-volt power to programmable thermostats, ensuring consistent performance and functionality. It is compatible with all 24-volt thermostats and can be installed with minimal effort. The adapter includes a wire saver module which allows for the use of a thermostat without rewiring the system for a common wire. This product is particularly useful in older homes where the HVAC system may not have originally included a C-Wire.
