Input power can be replaced. For safety, the GL-235 must be run to the ground terminal on next page. Power input Turn off power at back of 5 feet (horizontally) from the pool or spa. For other temperatures. Voltage measurements should be moved to select 12VAC output operation. Ohm measurements made with an adjustable, calibrated water temperature high limit. The GL-235 also has a high voltage output for specific grounding requirements. Enabled...

Operation For normal operation place the switch in section marked "Low Voltage (LV) : Solar Valve" to correct. Move the switch to "MANUAL OFF" and verify that the valve(s) are off to "MANUAL TEST" and verify that both the "Heating" and "Cooling" indicators light and that all indicators except "Power...
