The Bard 8201-135BX Relay Cycle Timer is an OEM timing relay used in Bard wall mount and packaged HVAC equipment to help manage equipment staging and run-time timing logic with a default-off operating state at power-up. If your unit is short cycling or not sequencing the way the original control strategy intended, replacing a failed or inconsistent timer relay with the correct Bard part can restore dependable start and cycle control without field modifications. As a genuine Bard replacement, 8201-135BX is built to match the original electrical interface and timing function so it installs and operates like the factory component when you confirm part number compatibility for your specific model and serial range.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
