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

N

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

N

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

N

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

N

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

N

F to a high of 104

N

F for quick and

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

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

r-

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

N

F. Two

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

snap switches are recommended if freeze recirculation protection

is utilized. 

Important--see installation instructions before using

Recirculation Freeze.

SYSTEM TEST SWITCH: 

Allows the user to manually over-

ride the automatic function of the GL-235 and verify operation.
