The HTP 7855P-217 Main Control Board is an electronic control component used in coordinating the sequences of operations and safety monitoring of the heating equipment in HVAC systems. It operates using integrated circuitry, which receives signals provided by temperature sensors, pressure switches, and safety elements and sends commands to ignition components, pumps, and fans. It operates in EFTC and UFTC-140W-boiler hydronic HVAC systems. It is installed within the control compartment of the equipment, which contains wiring harnesses that are attached to the corresponding terminals, and power supply circuits. This controls ignition timing and signal operating conditions and controls connected components.
