WIRING EXAMPLES

SD-3PB SPECIFICATIONS

DESCRIPTION:
Electronic, digital controller designed for Heating or Cooling.
This controller has an internal, programmable (interval) timer.
When the timer starts the internal thermostat will control the output high power relays ( 1 or 2 relays on-board rated at up to 30Amp or 40Amp each ). When wired to a Heater or another load like a Fan or a Pump, they will control the temperature.
The temperature and the timer are preset by pressing the corresponding keys on the control panel.
One digital display shows both, the preset and the current temperature and the other shows the preset time and the current count down.
The output relays contacts are isolated for wiring to any low or high voltage source.

Other Features:
The probe may be wired up to 500 ft. ( 150 meters ) away from the controller with standard 2-conductor wire.
Quiet, Arc-Free switching of high power load.
The load output may be manually turned OFF and the temperature preset may be changed at any time.
The timer may be manually reset.
Optional Additional relay (for light, fan ) may ba activated by pressing a pushbutton on the control panel...
Additional relay(s) may be activated automatically by the internal program at a customized option.

The timer can count in seconds, minutes or hours depending upon the model.
The temperature units are Celsius or Fahrenheit as selected by an on-board jumper.
