PCB-POOL TO SPA MECH (S)

Intermatic #

188--00021A

The Intermatic 188--00021A is a printed circuit board assembly, used inside Intermatic pool and spa timer controls to handle the pool-to-spa switching mechanism. It replaces the internal mechanism board that manages the pool-to-spa function on the control it fits, rather than requiring the entire timer body to be swapped. It is sold as a bench or field service part for a licensed technician replacing a failed board rather than the entire control housing. In the AES catalog it is grouped under parts & accessories within the controls timers category. It is sold each rather than as part of a kit unless noted otherwise on the part itself.
