Description

The GL-235 is designed to meet the need for easy installation,
dependable operation, and serviceability. The GL-235 incorpo-
rates unique, microprocesser based construction to ensure relia-
bility and accurate performance. The GL-235 offers advanced
operating features to provide differential temperature control,
selectable high limit, programmable recirculation freeze protec-
tion, nocturnal cooling and optional booster pump control.

AUTOMATIC HEATING:

If the collectors are warmer than the

pool water by 4

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 within

1.5

F of the pool temperature or the pool temperature exeeds the

“desired temperature” set on dial.

AUTOMATIC COOLING:

(Field selectable option) If the col-

lectors are cooler than the pool water by 6

F or more, and the

pool is above the selected desired temperature, the valve will

rotate allowing cooling via the solar collectors. The heat dissipa-

tion will stop when the collectors rise within 3

F of the pool tem-

perature or the pool temperature is lowered below the set desired

temperature.

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 the temperatures from 70

F to a high of 104

F for quick and

easy, user-friendly operation. The temperature set indicates set

pool/spa temperature, and the GL-235 will automatically dete

mine if the water should be solar heated or cooled, thus maxi-

mizing the system capabilities.

TERMINAL STRIP CONNECTIONS:

For input power, and

sensor inputs. Controls also have industry standard 3 pin connec-
tors for both forward and reverse valve actuator operation and
screw terminal connectors.

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.

GL-235 VALVE OUPUT:

Rating is the industry standard 24

VAC. A jumper switches the output to 12VAC for compatibility
with older valve actuators. Output is fuse protected.

RECIRCULATION FREEZE PROTECTION:

(field selectable

operation) turns the GL-235 output ON, directing warmer

pool/spa water through the collectors when near freezing tempera-

tures are reached at the collector sensor. The GL-235 will allow

recirculation when the collector temperature rises to 42

F. Two

10K Ohm sensors are required for operation. One or more freeze

snap switches are recommended if freeze recirculation protection
