Gecko Hi Limit Sensor - Microspa USPA / U-Class - Plug In style for retrofit pcb's only

Gecko Microspa USPA / U-Class plug in Hi-Limit sensor. ALL USPA pcbs actually have a soldered on style hi-limit sensor - this is not the correct sensor for that unit. This sensor suits retrofit U-Class PCB's with a hi-limit socket for this plug in style hi-limit. If you have a failed Microspa pcb with a soldered hi-limit, its replaced by a modified Hydroquip 7500 pcb (with Gecko programming) that utilises this hi-limit sensor. (normal Hydroquip hi-limit sensors are in a stainless probe, externally mounted to the heater tube)
