York S1-6421652 2-Stage Circuit Board SSE W/Communication

The York S1-6421652 Two-stage circuit board is used for HVAC system equipment including air conditioners and heat pumps. This circuit board is the control center of the system in that it controls the operational stages of the compressor as well as other parts. It has two stages of operations that enable the system to provide better control of temperature and energy consumption than single-stage systems. Through interaction with other components of the system, the board adapts the performance to the existing conditions. This brings with it, factors such as decreased energy use, low noise levels, improved and steady temperature and humidity levels within the conditioned space, increasing the longevity of the HVAC system.
