STC-1000Pro TH / STC-1000WiFi TH
Intelligent Temperature and Humidity Controller

Introduction

STC-1000Pro TH / STC-1000WiFi TH is an integrated plug-and-play temperature and humidity controller. It has temperature and humidity integrated probe and is pre-connected to two output sockets to control temperature and humidity simultaneously.
The large LCD screen intuitively displays temperature, humidity, and other parameters. With the three-key design, it enables quick parameter setting, such as alarm limit, calibration, protection time, unit switching, etc. It is mainly used in aquarium, pet breeding, incubation, seedling mat, greenhouse, and other application scenarios.

Operation

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

3.2 Power-on
Please insert the power plug into the power socket to power on the controller (within the range of 100-240VAC). The screen will light up and display the temperature, humidity, and other readings.

3.3 Parameter Setting
Press and hold button for 3 seconds to enter the parameter setting mode, the buzzer will beep, and the LCD will display icon. In the menu setting, press button and the Tsv 3 parameter light will be on or flashes. When it is flashing, press or button to switch to the next parameter; when the parameter light is on, press or button to increase or decrease the setting value. In the menu setting, press and hold button for 3 seconds to save settings and exit; or the controller will save and exit setting mode after 30 seconds of idle.
The Tsv displays temperature-related parameters and Hsv displays humidity- related parameters.
For example, set TS and TD parameters into TS = 20°C and TD = 5°C respec- tively.as shown in Fig. 6.

1. Press button and release after the buzzer beeps (about 3 seconds);
2. Press button, and the parameter code will display TS;
3. Press button, and will flash, indicates TS parameter is ready to be set;
4. Press (or press and hold) button to change the value to 20;
5. Press button, and TPV will appear;
6. Press button, and the parameter code will display TD;
7. Press button, and TPV will flash,indicates TD parameter is ready to be set;
8. Press (or press and hold) button to change the value to 5;
9. Press button and release after the buzzer beeps (about 3 seconds) to exit the parameter setting.

Note: Dotted-line in the figure shows the numbers are flashing (ready for setting); solid-line shows the numbers stop flashing (value is set).
See the flow chart below to change other parameter values one by one. as shown in Fig. 7.

Function Description

4.1 Temperature Setting – TCH, TS, TD
Cooling mode (TCH = C)
When TPV (temperature-present value) is higher than TS + TD (temperature-set value + temperature differential), will appear, work1 will be turned on, and cooling will begin;
When TPV (temperature-present value) is lower than TS (temperature -set value), will disappear, work1 will be turned off, and cooling will stop.
For example: TS = 15°C, TD = 5°C, as shown in Fig. 8.

Heating mode (TCH = H)
When TPV (temperature-present value) is lower than TS – TD (temperature-set value – temperature differential), will appear, work1 will be turned on, and heating will begin;

When TPV (temperature – present value) is higher than TS (temperature -set value), will disappear, work1 will be turned off, and heating will stop. For example: TS = 15°C, TD = 5°C, as shown in Fig. 9.
4.2 Temperature Protection Time – TPT
WORK1 is a temperature socket and the time interval from its power-off  to power-on again should meet the time requirement for TPT. If not, or will flash.
This protection time requirement should also be satisfied when the controller is just powered on.
4.3 Temperature Alarm Limit- TAH, TAL
When TPV (temperature-present value) is higher than TAH (temperature alarm high limit), the temperature alarm high limit will be triggered and code will be displayed;
When TPV (temperature-present value) is lower than TAL (temperature alarm low limit), the temperature alarm low limit will be triggered and code will be displayed;
During the alarm, the buzzer makes a sound of “bi-bi-Biii” until the temperature is back to the normal temperature range; or press any button to mute the alarm.
During the temperature alarm limit, the output of WORK1 socket is not affected.
4.4 Temperature Calibration – TCA
The temperature can be calibrated if the temperature-present value deviates from the actual temperature.
TPV (temperature – present value after calibration) = TPV (temperature – present value before calibration) + TCA (temperature calibrated value).
4.5 Temperature Unit – CF
The temperature unit can be switched between Celsius and Fahrenheit.
The temperature related parameter values will be restored to factory default values after the temperature unit is changed.
4.6 Humidity Settings – HDH, HS, HD
Dehumidifying mode (HDH = D)
When HPV (humidity-present value) is higher than HS + HD (humidity set value + humidity differential), will appear, work2 will be turned on, and Dehumidifying will begin;

When HPV (humidity-present value) is lower than HS (humidity set value), will disappear, work2 will be turned off, and dehumidifying will stop.
For example: HS = 50% RH, HD = 10% RH, as shown in Fig. 10.
Humidifying Mode (TCH = H)
When HPV (humidity-present value) is lower than HS-HD (humidity set value – humidity differential), will appear, work2 will be turned on, and Humidifying will begin;
When HPV (humidity-present value) is higher than HS (humidity set value), will appear, work2 will be turned off, and humidifying will stop.
For example: HS = 50%RH, HD = 10%RH, as shown in Fig. 11.

4.7 Humidity Protection Delay – HPT
WORK2 is a humidity socket and the time interval from its power-o to power-on again should meet the time requirement for HPT. If not, or light will flash.
This protection time requirement should also be satisfied when the controller is just powered on.
4.8 Humidity Alarm High Limit – HAH, HAL
When HPV (humidity-present value) is higher than HAH (humidity alarm high limit), the humidity alarm high limit will be triggered and code will be displayed;
When HPV (humidity-present value) is lower than HAL (humidity alarm lower limit), the humidity alarm lower limit will be triggered and code will be displayed;
During the alarm, the buzzer makes a sound of “bi-bi-Biii” until the humid- ity is back to the normal humidity range; or press any button to mute the alarm. During the humidity alarm high limit, the output of WORK2 socket is not affected.
4.9 Humidity Calibration – HCA
The humidity can be calibrated if the humidity-present value deviates from the actual humidity.
HPV (humidity-present value after calibration) = HPV (humidity-present value before calibration) + HCA (humidity calibrated value).
4.10 Continuous Operating Time – COT
During humidity control, when COT≠0 and output conditions are met, WORK2 socket will work in on-o-on-off…. mode. COT is time on as well as time off. eg, if COT=10, the WORK2 output socket will turn on for 10 minutes and off for 10 minutes, then repeat.
When COT = 0 and output conditions are met, WORK2 output socket will not be affected by COT.
4.11 Backlight Time – BL
BL is the screen display time. When BL=0 indicates display is always on.

Equipment Installation

As a safety precaution, it is recommended to power on the equipment after the installation is completed.
The only installation method is by hanging the equipment. Please check the installation distance and screw size according to its application scenario before installation.
The schematic diagram of equipment installation is shown below:

Alarm

In the following circumstances during operation, the buzzer will give a “bi- bi-Biii” alarm, and at the same time, the alarm symbol on the screen will appear. Press any button to mute the alarm.

Restore Operation Function

7.1 Restore Factory Settings
When the controller is powered on and in non-setting parameter status, please press buttons simultaneously on the main controller and release until the screen turns off automatically. Wait for the equipment to restart automatically and restore to factory settings.
7.2 Restore Wi-Fi Network Settings (for STC-1000WiFi TH)
If you would like to reconfigure to a new Wi-Fi network, please keep the equipment in power-on status, press buttons and release when the symbol on the screen flashes. The icon will disappear after the network restoration is completed.
Please do not power off the equipment during the restoration process.
