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.
