Pentair MasterTemp & Max-E-Therm Heater Air Flow Switch 42001-0061S by Swimables | SW-41-061The Swimables SW 41 061 Air Flow Switch is a critical safety and ignition component for Pentair MasterTemp and Max E Therm pool and spa heaters. This switch monitors the pressure differential across the air metering orifice to verify adequate combustion airflow before ignition can proceed. Once the blower generates sufficient air movement, the AFS closes its contacts, completing the circuit to the hot surface igniter (HSI) and initiating the fuel

I really like the Timex Ironman Shock watches. They are very durable and reliable. Simple to use and modeled after the. Original Ironman watches of the late 80s and 90s. Buttons are clearly marked and easy to press. They used to make many colors of this Shock model of the watch inc a cool shiny red color my wife still has . I have been a runner many many years and at 65, am still out although a lot slower than my 20s. But Timex Ironman watches have. Been my constant companion on the roads and track for 35 years now.
