Unit with power cord and sensors Goldline GL-30 Solar Control Unit - 110
Volts
The Goldline GL-30
differential temperature control is designed to provide maximum operating
efficiency and flexibility to effectively manage today's innovative solar energy
systems. It is a continuation of the advanced electronic technology which
produced the popular C-30 and CM-30 controllers - standards of the solar
industry since 1975, with hundreds of thousands of units installed worldwide.
With an adjustable high limit of 50º-104ºF, the GL-30 is capable of handling
most differential temperature control functions for operation of domestic water
heating and sophisticated space heating and cooling. The GL-30 is designed to
control recirculation, drain-back and closed loop systems.
Replacement unit for CM30 and C30:
• Control does not include power cord or sensors [must be
purchased separately or in a package]
• Two
SB-10K sensors may be required. [sold separately]
NOTE: TD-GL & DIX-30 Temperature Displays are discontinued
LED Indicators
Three highly visible LEDs
show:
• Power to control
• Power out from
control
• Power out from control due to a
recirculation mode to protect
• the system from
freeze damage.
GL-30 Output
The GL-30 output is rated
at 20 Amps and is designed to directly
operate a pump or fan for heat
collection when the controller is sensing an appropriate temperature
differential.
Differential
The GL-30 has an
adjustable differential with a range of 8º to 24ºF. Solar systems with long
pipe runs normally require a higher
turn-on differential temperature, and
open loop systems with short pipe runs usually require a lower turn-on
differential temperature for optimum performance. The GL-30 offers versatility
to tailor controls to numerous specific systems designs.
Storage
High Limit
The GL-30 allows you to set a high limit storage
temperature from 110º to 230ºF.
Recirculation Freeze
Protection
Recirculation freeze protection, when enabled, turns the
GL-30
output on to circulate warmer storage water through the collectors
when near freezing temperatures are reached at the collector
sensor.
System Test Switch
The system test switch
manually switches the GL-30 to ON, AUTO,
or OFF for complete control over
the system at all times.

General
Control and Sensor Trouble-Shooting Tips:
All of the GoldLine
(formally Independent Energy) controls (including C30, CM30, G30 and GL30
series) and some of the Heliotrope General (HG) DTT series controls incorporated
the use of 10k sensors. Some of the earlier HG controls and some other
lesser known brands used 3k sensors.
To determine the type of sensor, the
resistance must be measured in ohms (using a volt/ohm meter) when the sensor is
at 77 degrees F. 10k measures 10,000 ohms and 3k measures 3,000 ohms. As
the temperature goes up, the resistance goes down.
Resistance can
be checked at any temperature, and then
convert the ohm reading measured to
the temperature equivalent
by using the conversion
chart.
