Description
The SP-300 control is a two stage, general pur-
pose, temperature control for use in HVAC, re-
frigeration, and industrial applications. The set-
point temperature range is user selectable from:
-30°F to +100°F or 70°F to 200°F
The control provides two staged isolated SPDT
relay contacts. The relays are controlled by com-
paring the thermistor temperature sensor to a
setpoint. The SP-300 allows the user to select
either “heat” mode (both relays operate on tem-
perature fall) or “cool” mode (both relays operate
on temperature rise) or “heat/cool” mode (output
1 relay operates on temperature fall and output 2
relay operates on temperature rise). The control
setpoint can be set using the internal setpoint dial
(factory setting) or a remote setpoint dial (see
GoldlineRSP-30remote setpoint on page 6). The
SP-300 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 24VDC, 24VAC,
115VAC or 240VAC power source. Each set of
relay contacts is completely isolated so the out-
puts can switch any voltage, regardless of the SP-
300 power source. Furthermore, one relay output
can switch high voltage, the other switch low
voltage. A movable divider is provided to sepa-
rate high and low voltage wiring compartments.

Setup
The SP-300 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 at-
tempting to install or wire the control. The jumper
functions and appropriate positions are shown in
the diagram below.

Mounting
The SP-300 is designed for mounting indoors,
protected from the weather and with non-con-
densing humidity. For outdoor use or in moist
environments use a Goldline RE-1 raintight en-
closure. 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 wiring 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 electri-
cal wiring use shielded cable (Belden 8760 for
indooruseorBelden8428foroutdooruse). Ground
the shields to one of the SP-300 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 termi-
nals labeled "3" and "4".
Power input
The SP-300 control requires power to operate.
Either 24VDC, 24VAC, 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.

Output wiring
The SP-300 outputs are isolated (dry) contacts
which are ideal for many control applications.
Because there is no output voltage, if you are
directly controlling a load (e.g. pump, blower,
valve, etc.) then you must connect a source of
power to the SP-300 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. If wiring for a heat/cool application, be
sure to wire the heat load across the Output 1
relayandcool load across output2relay. Refer
to the diagram below for example wiring.

off when the sensor falls to the setpoint. Output 2
will turn on when the sensor temperature rises to
the setpoint plus the stage offset plus the differen-
tial-2. Output 2 turns off when the sensor falls to
the setpoint plus stage offset.
1 Stage Heat/1 Stage Cool mode
Output 1 is in "heat" mode and operates identi-
cally to Output 1 described in “heat” mode. Out-
put 2 is in “cool” mode and operates identically to
Output 2 described in “cool” mode above.
Refer to the diagrams below for control logic.
The SP-300 operation is straightforward.
2 Stage Heat mode
Output 1 will turn on when the sensor temperature
falls to the setpoint minus the differential-1 and
turn off when the sensor rises to the setpoint.
Output 2 will turn on when the sensor temperature
falls to the setpoint minus the stage offset minus
the differential-2. Output 2 turns off when the
sensor rises to the setpoint minus stage offset.
2 Stage Cool mode
Output 1 will turn on when the sensor temperature
rises to the setpoint plus the differential-1 and turn

Anti-Cycle
This feature is used to prevent an output from
turning on within 4 minutes of the output turning
off, regardless of temperature. Each output is
independent and has its own Anti-Cycle timer.
The internal timer starts counting immediately
after the control output "satisfies" (output relay

turn off). The output relay is only allowed to
energize AFTER the timer has completed count-
ing. If the timer hasn't finished counting, the
corresponding 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.

Using the optional RSP-30
The RSP-30 is a remote setpoint adjustment and
can be mounted up to 500 feet away from the SP-
300 control. Be sure to move the Setpoint Selec-
tion jumper to the "External" position and the
Setpoint Range to the desired temperature range,
when using the RSP-30. See included instruc-
tions for mounting information. The RSP-30
uses a 3 conductor connection to the SP-300
control. A 3 position screw terminal block on the
RSP-30 is labeled "1", "2", and "3", similar to the
screw terminal located under "R" and "C" on the
SP-300. Using 3 conductor wire, connect each
pair of similarly marked screw terminals. Refer to
the diagram below.
Adjustments
Adjust the setpoint, differential 1, differential 2
and stage offset to the desired settings.
