Goldline SP-300 Quick Start Manual

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
Goldline RSP-30 remote 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.
