Description
York S1-031-03886-000 Two-Stage PHE Circuit Board with PWM Control
The York S1-031-03886-000 is an OEM replacement circuit board engineered for two-stage plate heat exchanger (PHE) systems equipped with pulse width modulation (PWM) control. Designed to York’s exacting factory specifications, this board delivers reliable, accurate management of two-stage heating and cooling operations while enabling precise PWM-based modulation for enhanced system efficiency and comfort.
Key Features
- OEM York replacement circuit board — direct factory-spec fit
- Supports two-stage PHE (plate heat exchanger) operation for improved efficiency
- Integrated PWM (pulse width modulation) control for variable-speed fan or pump modulation
- Engineered for precise staging and reliable system sequencing
- Designed for straightforward drop-in replacement with compatible York equipment
- Helps maintain consistent comfort levels through accurate two-stage control logic
Application
This circuit board is intended for use in York HVAC systems utilizing plate heat exchanger technology with two-stage operation. The onboard PWM functionality allows the system to modulate output — such as fan speed or pump flow — in response to real-time demand, reducing energy consumption and wear on system components compared to single-stage or on/off control.
