We have an inground pool with the GL235 Control panel. a few weeks back, the Check Sensor light started flashing. I replaced the sensor(one on the roof ofcourse) but that did not fix it(still blinked), so then saw there may have been a break in the wire, so replaced that. This stopped the Check Sensor from blinking. , but created a new issue.
The Unit will not come on automatically. If I slide the switch to manual, the value opens and it works, but the auto with the temp dial at the highest, does nothing. The heat/cool lights don't even come on. Not sure what could be causing this.
The only thing I did notice is that the roof sensor was not connected into the pipe. This seemed strange but thought it was this way to get the outside temp, but not sure. We have had the unit for about 5 yrs with no issues, but late last year, we did have one of the collectors changed(Fafco) since it was leaking. I wonder if the technician forgot to drill the hole for the sensor.
Do you think this is why the automatic setting is not turning on? we live in AZ, so the daytime temp is really warm, and should start heating the water. Very Confused AZ
