Description
The SP-33 and SP-33D controls are single stage,
general purpose, temperature controls for use in
HVAC, refrigeration, and industrial applications.
The setpoint temperature range is user selectable
from:
40°F to +104°F
The SP-33 control provides one isolated SPDT
relay output while the SP-33D provides two (ef-
fectively DPDT). The relays on both the SP-33
and SP-33D 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-33 remote set-
point on page 7). The SP-33 and SP-33D 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 con-
tacts are completely isolated so the outputs can
switchanyvoltage,regardlessofthepowersource.
On SP-33D 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-33 and SP-33D 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-33 and SP-33D 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 informa-
tion on the wide range of interchangeable Gold-
line temperature sensors.
The temperature sensor wires run back to the
control should be connected to the screw termi-
nals labeled "3" and "4". See diagram on page 5.
Power input
The SP-33 and SP-33D 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 groundsto thegreen
screw provided or use grounding clips (eg Steel
City “Gee clips” or Raco #975). Refer to wiring
diagram below.

Output wiring
SP-33: The SP-33 provides one set of isolated
SPDT relay outputs. If you are directly control-
linga load(egpump, blower,valve, etc),youmust
connect a source of power through this output
relay. “NO” are normally open contacts which
close when the control output is on. “NC” are
normally closed contacts which open when the
control output is on. Refer to the sample diagrams
shown below.
SP-33D: The SP-33D provides two sets of iso-
lated SPDT relay outputs. If you are directly
controlling a load (eg pump, blower, valve, etc),
you must connect a source of power through these
output relays. “NO” are normally open contacts
which close when the control output is on. “NC”
arenormallyclosed contacts whichopenwhen the
control output is on. Refer to the sample diagrams
shown below.

LEDs
The SP-33 and SP-33D use 2 LED indicators to
display the status of the control. The diagram on
page 2 shows the location of each LED. Refer to
the chart below for LED information.
Anti-Cycle
This feature is used to prevent the output from
turning on within 4 minutes of output turning off,
regardless of temperature. An internal timer starts
counting immediately after the control "satisfies"
(output relay(s) turn off). The output relay(s) are
only allowed to energize AFTER the timer has
completed counting. If the timer hasn't finished
counting, the Output LED will blink.
NOTE: When input power is first applied to the
control, the Anti-Cycle internal timer automati-
cally starts and will prevent the output relay(s)
from energizing until after the timer has finished
counting.
The SP-33 and SP-33D operation is straightfor-
ward.
Cool mode: The control output will turn on when
the sensor temperature rises to the setpoint tem-
perature plus the differential amount. The control
output will turn off when the sensor temperature
reaches the setpoint temperature.
Heat mode: The control output will turn on when
the sensor temperature falls to the setpoint tem-
perature minus the differential amount. The con-
trol output will turn off when the sensor tempera-
ture reaches the setpoint temperature.
Some sample diagrams of the control logic are
shown below.

Using the optional RSP-33
The RSP-33 is a remote setpoint adjustment and
can be mounted up to 500 feet away from the SP-
33 or SP-33D control. Be sure to move the
Setpoint Selection jumper to the "External" posi-
tion when using the RSP-33. See included in-
structions for mounting information. The RSP-33
uses a 3 conductor connection to the SP-33/33D
controls. A 3 position screw terminal block on the

minals. Refer to the diagram below.

All Goldline controls use 10K thermistor sensors.
When disconnected from the control, the sensor
will read 10 K ohms at 25°C/77°F. Refer to the
chart below for the resistance at other tempera-
tures. For a given temperature, the resistance is
accurate to +/- 1%. For a given resistance the
temperature is accurate to +/- 0.5°F.
