Unlike many timer models with only two buttons, the four buttons on the Omega PTC-21 allows for quick and convenient time changes (one for each digit). Also handy is the non-volatile memory that allows the timer to remember where it left off if ever power is cut during a countdown.

If you have trouble sourcing the PTC-21, the Eagle B506-5001 timer is a direct replacement (identical functionality, no wiring changes required). If purchasing a used unit, make the socket is included (required for connecting wires).

If you choose to use a different brand/model, make sure that it is 1/16 DIN sized, can be powered by 120VAC, counts down from at least 90 minutes by the second, and supports an alarm. Please note that if a different timer is used, the wiring and initial setup instructions will most likely be different.
