Xetron STC-1000Pro Smart Digital Thermostat User Manual

Overview

The STC-1000Pro is a plug-and-play smart digital temperature controller. It has two pre-wired heating and cooling outlets that automatically keep your appliances at ideal temperatures and keep them safe and reliable due to V-O classified flame-retardant ABS materials. Meanwhile, its three-button design and 2.5″ LCD provide intuitive temperature viewing and parameter settings, such as high/low temperature alarm, temperature calibration, “C/”F unit switch, and cooling protection time. The STC-1000Pro with UK/EU/US versions can be widely used in areas that require automatic temperature controls, such as homebrewing, aquariums, incubation, pet breeding, seedling heat mats, culture fermentation.

Note:

1. Csp(Cooling start point) = TS(Temperature Set-point) + CD(Cooling Differential)
2. Hsp(Heating start point) = TS(Temperature Set-point) – HD(Heating Differential)

Operation

Incorrect operation may cause serious damage to you or your device. Please make sure you read and understand the following procedures before starting.

Probe Installation
Incorrect operation may cause serious damage to you or your device. Please make sure you read and understand the following procedures before starting. Plug the temperature probe fully to the bottom of the main controller’s headphone jack. Otherwise, a buzzer alarm will be triggered, and the “Err” code will show on the LCD after powering the controller.

Power On

Plug the controller into a 100V to 250V power outlet, the LCD will light up and display temperature and other parameters.

Parameter Viewing

Press or to enter parameter viewing mode.
Press to view the parameters and relative values in ascending order:
TS→CD→HD→PT→AH→AL→CA. The parameter details are in 2.4 Parameter Settings. Note: The controller will automatically exit viewing mode after 5 seconds of inactivity.

Parameter Settings

STC-1000Pro supports parameter settings by buttons.

Button Operation

Press and hold button for 3 seconds to enter the parameter setting mode, the buzzer will beep and the LCD will display icon. Press button to switch to the next parameter, then press or to increase or decrease the setting value; or long press or to increase or decrease quickly. Press and hold for 3 seconds to save settings and exit; or the controller will save and exit setting mode after 15 seconds of inactivity. See the flow chart below for quick parameter setting procedures:

Parameter Functions

Temperature Setting – TS, HD, CD, PV, SV

When the controller is in normal operation, the PV displays the current value; the SV displays the set value by adjusting the TS (Temperature Set-point), HD (Heating Differential), and CD (Cooling Differential) parameters (Cooling Differential). It will switch between cooling and heating modes.

Cooling Mode:

• When PV (Current Value) ≥ TS (Temperature Set-point) + CD (Cooling Differential), the controller enters the cooling mode, the cooling icon is on and the cooling outlet starts to output.
  If the cooling icon flashes, the compressor is under protection status, please see 3.1.2
  Protection Time – PT for further information.

• When PV (Current value) ≤ TS (Temperature Set-point), the controller exits the cooling mode, the cooling icon is off.

Heating Mode:

• When PV (Current Value) ≤ TS (Temperature Set-point) – HD (Heating Differential), the controller enters heating mode, the heating icon is on and the heating outlet starts to output.
• When PV (Current Value) ≥ TS (Temperature Set-point), the controller exits heating mode, the heating icon is off.

Example:
If set TS = 25°C, CD = 3°C, HD = 3°C:
Csp (Cooling start point) = TS + CD = 28°C,
Hsp (Heating start point) = TS – HD = 22°C.
When PV (current value) ≥ 28°C(Csp), the controller automatically enters cooling mode. When
PV ≤ 25°C(TS), the controller automatically exits cooling mode.
When PV ≤ 22°C(Hsp), the controller automatically enters heating mode. When PV ≥ 25°C(TS), the controller automatically exits heating mode.

Protection Time – PT (Cooling Mode Only)
Frequent start/stop may influence or even shorten the service life of your appliance; we suggest you to set the parameter PT (Protection Time, i.e. cooling start delay time), to protect your appliance. Please set it according to your requirements.

Example: When PT is set to 3 minutes, PV (Current Value) > Csp (Cooling start point), the controller will enter cooling mode if either condition below is satisfied:

• The controller is powered on for more than 3 minutes;
• The interval between two adjacent cooling modes is more than 3 minutes

High Alarm Limit – AH
When PV (Current Value) ≥ AH (High Alarm Limit), high temperature alarm will be triggered, the LCD displays error code “EAH”, the icon and buzzer beeps promptly. Press any button to mute the buzzer, but the error code will remain until PV < AH.

Low Alarm Limit – AL
When PV (Current Value) ≤ AL (Low Alarm Limit), low temperature alarm will be triggered, the LCD displays error code “EAL”, the icon and buzzer beeps promptly. Press any button to mute the buzzer, but the error code will remain until PV > AL.
Note: The controller will work normally during AH or AL alarms.

Temperature Calibration – CA
When PV (Current Value) deviates from the standard or actual temperature, please use the parameter CA to correct it. The calibration value could be positive, 0 or negative and PV (calibrated) = PV (before calibration) + CA (temperature calibration).

Celsius/Fahrenheit – CF
The controller supports Celsius or Fahrenheit display. The US version default unit is in Fahrenheit, the UK/EU version default is in Celsius. If the default is different from your preferred unit, please modify the parameter CF as shown in 2.4 Parameter Settings.

Installation

For your personal and appliance’s safety, we suggest you power on the controller after the installation finishes.

This controller supports hanging-mount only, please check and confirm the installation distances and nails size before installation. The details are shown below for reference:

Cooling/Heating Outlet

Take care when using electricity!

Please plug your refrigeration and heating appliances into the corresponding cooling and heating outlets to the controller. If all status is normal, the controller will start cooling or heating automatically according to the parameters, the corresponding icon will show prompt to indicate the current working status.

Note: If you only need to connect one appliance, or do not use the outlet for a long time, please put it away to prevent potential damage to the controller.

Error Code

If the following conditions occur, the buzzer will beep and error code will show on the LCD to alert. Press any button can mute the buzzer but error code will remain until the problems solved.

• When LCD screen displays error code “Err”:
  The probe may be disconnected or not installed correctly. Please try to re- install the probe. If the “Err” code remains on the screen, please replace with a new one ASAP.

• When LCD screen displays error code “EAH”:
  The controller is in high temperature alarm status as current temperature is above high alarm limit (PV ≥ AH). Please check and solve it ASAP to avoid any damage or loss.

• When LCD screen displays error code “EAL”:
  The controller is in low temperature alarm status as current temperature is below the low alarm limit (PV ≤ AL). Please check and solve it ASAP to avoid any damage or loss.

Reset

Please power on the controller before reset.

Reset to Default Parameters

Press and hold all three buttons ( ) simultaneously until the screen is o. Release the buttons and the controller will auto-restart after reset to default parameters.
