Installation

Mounting

The GL-235 is designed for outdoor use. Mount the box vertically with the knockouts facing

downward. For safety, the GL-235 must be a minimum of 5 feet (horizontally) from the pool or

spa.

Power input

Turn off power at circuit breaker before wiring. Remove the internal panel to expose the wiring

connections. Either 115VAC or 240VAC can be used. Refer to the input wiring diagram (Figure 1)

on next page. WARNING: Applying 240VAC to the 120VAC input terminals will cause

permanent damage to the control.

Grounding

Refer to NEC and local codes for specific grounding requirements. In general, a separate ground

conductor must be run to the ground terminal on the pool service panel.

Low Voltage (LV) output: Solar Valve

The GL-235 controls a single valve. In most applications this is the solar valve, which diverts water

through the collector panels or through the normal pool loop depending on conditions.

Description

The GL-235 is a differential temperature control for solar heating of pools, spas, and hot tubs. It

provides differential temperature control with an adjustable, calibrated water temperature high limit.

Automatic nocturnal cooling (for pools that overheat in hot climates) and recirculate freeze

protection functions can be enabled/disabled via internal jumpers.

Input power can be either 115 or 240 VAC. The output controls a 24VAC automatic valve actuator.

For older systems with 12VAC valves, an internal jumper can be moved to select 12VAC output

operation. The GL-235 also has a high voltage output for controlling a filter pump or booster pump.

Temperature/Resistance/Voltage

All Goldline controls use 10K thermistor sensors. When disconnected from the control the sensor

will read 10K ohms at 25ºC/77ºF. Refer to the chart below for the resistance at other temperatures.

For a given temperature, the resistance reading should be accurate to ±1%. For a given resistance

reading, the temperature reading should be accurate to ±0.5ºF. Voltage measurements should be

accurate to ± 2%. Ohm measurements made with sensor disconnected from unit. Voltage

measurements made with sensor connected to unit and power applied. Sensor voltages are DC volts.
