Description
The SP-30 and SP-30D controls are single stage,
general purpose, temperature controls for use in
HVAC, refrigeration, and industrial applications.
The setpoint temperature range is user selectable
from:
-30°F to +100°F or 70°F to 200°F
The SP-30 control provides one isolated SPDT
relay output while the SP-30D provides two (effectively DPDT). The relays on both the SP-30
and SP-30D are controlled by comparing the
thermistor temperature sensor to the adjustable
setpoint temperature. The user can select either
“heat” mode (relay operates on temperature fall)
or “cool” mode (relay operates on temperature
rise). The control setpoint can be set using the
internal setpoint dial (factory setting) or a remote
setpoint dial (see Goldline RSP-30 remote setpoint on page 7). The SP-30 and SP-30D also
features a plug in connector for a TD-30 Digital
Display Monitor. The TD-30 snaps into the cover
for easy mounting and displays both sensor and
setpoint temperatures.
Power can be provided from a 24VAC, 24VDC,
115VAC or 240VAC power source. Relay contacts are completely isolated so the outputs can
switch any voltage, regardless of the power source.
On SP-30D models, one relay output can switch
high voltage, the other switch low voltage. A
movable divider is provided to separate high and
low voltage wiring compartments.

Setup
The SP-30 and SP-30D can be configured to
operate in a variety of applications using jumpers
located on the circuit board (see diagram below).
Set these jumpers based on your application,
before attempting to install or wire the control.
The jumper functions and appropriate positions
are shown in the diagram below.

Mounting
The SP-30 and SP-30D controls are designed for
mounting indoors, protected from the weather and
with non-condensing humidity. For outdoor use
or in moist environments use a Goldine RE-1
raintight enclosure. Use the mounting screws
supplied or optional mounting bracket (consult IE
factory).
Sensor Mounting and Wiring
To maximize temperature measurement accuracy
securely mount the sensor and then insulate it to
protect it from the effects of ambient temperature.
18 AWG twisted pair wire should be used for
normal indoor runs. Sensor wiring run outdoors
must be rated for outdoor use and ensure that wire
connections are protected from the weather. For
long runs or runs near other electrical wiring use
shielded cable (Belden 8760 for indoor use or
Belden 8428 for outdoor use). Ground the shields
to one of the control's cover screws. If the SW
sensor supplied with the control does not meet
your needs, contact your distributor for information on the wide range of interchangeable Goldline
temperature sensors.
The temperature sensor wires run back to the
control should be connected to the screw terminals labeled "3" and "4". See diagram on page 5.
Power input
The SP-30 and SP-30D controls require power to
operate. Either 24VAC, 24VDC, 115 or 208/
240VAC can be used. Be sure to only power the
control with ONE power input. Connect 24VAC
to the “R” and “C” terminals; 24VDC to the “R”
(+) and “C” (-); 115VAC to the terminals marked
“115VAC” or 208/240VAC to the terminals
marked “240VAC”. Connect grounds to the green
screw provided or use grounding clips (eg Steel
City “Gee clips” or Raco #975). Refer to wiring
diagram below.
