Functional Devices RIBMNLB-6 Logic Board R-410A This model is technically identical

This model is technically identical to the 313A08 solenoid valve

it requires a field technician to physically inspect the heat exchanger and venting for blockages or cracks before restoring furnace operation

The unit is built with an aluminum lined inlet body and a 1/4" compression coupling inlet fitting

Look for signs of "starving" (low suction pressure

Functional Devices RIBMNLB-6 Logic Board R-410A This model is technically identicalThe Functional Devices RIBMNLB 6 is a 6 input logic board designed for high reliability AHU fan safety alarm circuits and general purpose logic applications. This track mount device streamlines complex relay logic by integrating six normally closed (N C) inputs that control a single master relay. When any of the monitored inputs openwhether from a low temperature alarm, smoke detector, or high pressure switchthe master relay trips, providing an
