Description
The Johnson Controls P100AA-3 Fan Cycling Switch is the best control solution for the circulation of air in the HVAC systems. This small switch which is housed in a rather hard plastic casing (size 3.0 x 2.5 x 2.0 es) is a Single Pole Single Throw (SPST) switch. In simple words, it works like a toggle switch. The P100AA-3 is intended for normal voltage 120 VAC and has the current of 10 A, so it is suitable for controlling most standard HVAC fans. Here’s where the temperature control comes in, when the temperature rises to 225°F the switch turns on the fan (cut-in) to maintain adequate flow of air and cooling of the system.
