 Description
The GL-235 is designed to meet the need for easy installation,
dependable operation and serviceability. The GL-235 incorporates
unique, microprocessor based construction to ensure reliability and
accurate performance. The GL-235 offers advanced operating features
to provide differential temperature control, selectable high limit,
programmable recirculation freeze protection, nocturnal cooling and
optional booster pump control.
Automatic Heating: If the collectors are warmer than the pool water
by 4 degrees or more, and the pool is below the selected desired
temperature, the valve will rotate allowing heat collection. This
heat collection will stop when the solar sensor falls to with 1.5
degrees of the pool temperature or the pool temperature exceeds the
desired temperature set on the dial.
LED Indicators: Show the status of the system operation. Four highly
visible LED's show 1) power to the control, 2) power output directing
valves and/or pump to collect heat (heating), 3) power output directing
valves and/or pump to dissipate heat (cooling), 4) sensor fault indicator
shows sensor(s) not operating properly.
Single Setting For Desired Temperature: The GL-235 logic is set by a
single dial adjustment with the desired pool/spa temperatures clearly
indicated. The dial is calibrated with temperatures from 70F to 104F
for quick and easy operation.
GL-235 Output: Rating is the industry standard 24 VAC. A jumper switches
the output to 12 VAC for compatibility with older valve actuators. Output
is fuse protected.
System Test Switch: Allows the user to manually override the automatic
function of the GL-235 and verify operation.
