The Prostat Add-A-Wire Control and Diode kit is a specialized HVAC wiring solution designed to expand the capabilities of your existing thermostat cable without the need to pull new wires through your walls. This kit is an essential accessory for modernizing heating and cooling systems, particularly when upgrading to a smart thermostat that requires a common (C) wire for constant power. By utilizing a control module and a diode, this component allows two separate signals to be sent over a single wire, effectively turning a four-wire cable into a five-wire system or a three-wire cable into a four-wire system. It is a reliable, time-saving electrical component for HVAC technicians and homeowners looking to improve system functionality with minimal structural disruption.
