monitoring the internal cabinet air temperature to prevent heat exchanger damage and system overheating

which should be torqued to 95 in-lbs for optimal seating

When troubleshooting a furnace blower that won't shut off or a unit that is short cycling

while higher voltages will likely cause immediate coil failure

ensuring a precise fit for older or specialized flat face flange configurations where a standard 8-hole gasket would fail to provide uniform compression

Functional Devices RIBH1C Relay monitoring the internal cabinet airThe Functional Devices RIBH1C Relay is a heavy duty enclosed pilot relay engineered for building automation and HVAC industrial control circuits. This SPDT (Single Pole Double Throw) relay features a unique dual coil input design, capable of accepting 10 30VAC DC or 208 277VAC, making it a versatile "Relay in a Box" for multi voltage field applications. With a 10 Amp resistive contact rating, the RIBH1C is designed to handle pilot duty, ballast
