Goldline SP-33 Quick Start Manual

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
switch any voltage, regardless of the power source.
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.
