STC-1000 | Operating Instructions

Function

The STC-1000 is a multi purpose Temperature Controller. It allows for temperature controller, adjustable hysteresis, offset calibration and output relay delay. An alarm will sound if the temperature limits are exceeded or a sensor issue is detected

Controls

• Cool Indicator

• Heat indicator

• 3 digit LED Display

• Power Button - Power On/Off, Confirm Parameter Adjustment

• Button - Set

• Up Button

• Down Button

• To turn the STC-1000 OFF or ON, press and hold the Power Button for three seconds

• Under normal working conditions, the STC-1000 displays the current measured temperature. The Heat and Cool indicator will illuminate to show if the Heating or Cooling relay is active

• Cooling activates when the measured temperature is greater than the Set Point temperature and the Hysteresis. If the Cooling indicator is flashing, this indicates that the Compressor Delay is active. Cooling will begin when this period ends. When the measured temperature reaches the Set Point temperature, the Cooling Relay will deactivate and cooling will stop.

• Temperature Set Point - this is the set point temperature that you wish to maintain using the STC-1000 Controller

• Hysteresis - this is the allowed value above/below the set point before cooling/heating activates

• Compressor Delay Time - this si the delay before the Cooling relay activates (to prevent excessive compressor use)

NOTE: If the STC-1000 is pre-installed then the default settings mat differ from the above

If there is a large variance between the displayed temperature (IE the temperature of the temperature probe and the actual internal temperature (as measureed by a calibrated thermometer) then the Temperature Offset can be adjusted from -10°C to 10°C

A Temperature Offset will offset the displayed temperature by the entered amount.

Thus, if the displayed temperature is 2°C but the actual internal temperature is 4°C, and offset of +2°C is required.

Note: In most cases this is not necessary to be adjusted.

This indicates the temperature probe is unplugged, damaged or faulty. Press any key to cancel the alarm and investigate the source of the error.

This indicates the measured temperature as exceeded the temperature mesuring range (-50°C - 99°C). Heating and Coolling will be suspended. Press any key to cancel the alarm. The system will revert when the measured temperature is back within range.

• Ensure correct wiring is followed (see below for wiring diagram)

• Ensure unit is not connected to electricity when wiring unit

• Do not use unit in areas that exceed temperature, humidity range of the device

• Ensure it is connected to a suitable power outlet
