Model GL-235-LV-HV
The model GL-235-LV-HV has two outputs: 1) Selectable low volt-
age output for 12/24 VAC valve actuator. Wire via 3 pin connectors
or terminal block (compatible with older actuators). 2) Isolated con-
tact, high voltage output for 120/240 VAC booster pump or time
clock override. Order sensors and freeze snap switches separately.
Model GL-235-LV
The GL-235-LV is similar to the GL-235-LV-HV, but has a low volt-
age output only.
Temperature Sensors
All Goldline temperature sensors are 10K Thermistors which are
accirate to +/-
2N
F. The sensors are double-dip potted in silicone for
maximum protection from moisture.
PC: Multi-purpose sensor that can be used for both Solar (surface
mount) or Pool/Water (drill-in plastic piping).
SC-1/4: Brass screw-in sensor with
3
” NPT pipe thread. Screws
directly into drain plug on the pump strainer basket.
Freeze Snap Switches
Goldline recommends the use of one or more freeze snap switches to
be wired in series with the solar sensor if the recirculate freeze pro-
tection feature is being used. Both snap switch models operate identi-
cally, however, the GC-1 is designed to meet the highest aerospace &
military specifications.

Goldline Combo (GLC)
The “GLC” package contains everything required to automatically
control most solar pool heating systems. The “GLC” provides the
industry’s #1 best selling control, valve, actuator, and sensors togeth-
er in one box. The “GLC” makes inventory control easier, ensures all
parts arrive at the job site, and components remain protected in facto-
ry-fresh condition. The Goldline “GLC” consists of the GL-235-LV
or GL-235-LV-HV control, a 24 VAC actuator, a valve (see chart)
and 2 sensors (see chart). For GLC with the GL-235-LV-HV control
add HV after GLC in Model number. MODEL
