I'm having a heck of a time identifying this control panel to figure out how to enter programming mode. I don't think it's a TP600, as there's a mode button and the light button is on the opposite side of the temp control buttons. When I press a temp control button, the LCD does not blink to enter programming mode. I've tried pressing and holding the mode button, and various combinations, to no avail.
I'd prefer to avoid removing the overlay pull the retaining screws. So far I've been able to view the back from inside the Looking at the back, I can make out that it says Balboa 22025 printed on the back of the circuit board, but searching that has not provided results. Can someone please ID this unit and point me to the user manual?
