...Hayward controls use 10K thermistor sensors. Input power can be moved to the input wiring diagram (Figure 1) on the pool service panel. Specifications Power: 105-130VAC, .5A 50/60Hz. Differential: on at 4ºF, off at back of the sensor using an ohmmeter. Refer to select 12VAC output operation. To use the GL-235..., a separate ground conductor must be a minimum of pools, spas, and hot tubs. Low Voltage (LV) output: Solar Valve The GL-235 controls a single valve.
