• INTERLOCKING RELAY

Bard 8201-025 is an OEM interlocking relay used in Bard wall mount HVAC control circuits to coordinate equipment operation and prevent conflicting calls, helping protect components by ensuring the correct sequence and electrical interlocks during heating or cooling operation. If you are troubleshooting intermittent operation, improper staging, or a control circuit that is not switching as designed, replacing the 8201-025 with the correct Bard factory relay helps restore reliable control logic and proper system response. Match the part number to your unit model and wiring diagram to confirm terminal layout and coil requirements before ordering, since relays with similar functions can have different ratings and configurations.
