Description

The Elitech Temperature and Humidity Controller STC-1000Pro is a feature-rich device that offers precise temperature and humidity control. The STC-1000Pro's dual display shows both temperature and humidity levels, ensuring that you are always aware of the current conditions. With programmable temperature and humidity settings, you can easily customize the device to suit your specific needs. The built-in alarm function alerts you when temperature or humidity limits are exceeded, providing an extra layer of monitoring and protection. Additionally, the STC-1000Pro supports external sensors, allowing for more versatile and accurate measurements. The RS485 interface enables data communication and remote control, enhancing the device's functionality and convenience.

Operation

Important: Improper use of the product may cause inJury or product damage. Please read, understand and follow the operating steps below. 

Sensor Installation 

Plug the sensor fully into the headphone jack from the button of the main controller. 

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.

Parameter Setting 

1. Press and hold button for 3 seconds to enter the parameter setting mode, the buzzer will beep, and the LCD will display  icon. 
2. In the menu setting, press the button and the Tsv3 parameter light will be on or flashes. When it is flashing, pressor button to switch to the next parameter; when the parameter light is on, press􀀊 or 􀀋button to increase or decrease the setting value. 
3. In the menu setting, press and holdbutton 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 humidity­related parameters. 

For example, set TS and TD parameters into TS = 20'[ and TD = S'C respectively.as shown in Fig. 6. 

• Press button and release after the buzzer beeps (about 3 seconds); 
• @ Pressbutton, and the parameter code will display TS; 
• Press button, and will flash, indicates TS parameter is ready  to be set; 
• Press (or press and hold)button to change the value to 20; 
• Press button, and TPV will appear; 
• Pressbutton, and the parameter code will display TD; 
• Press button, and TPV will flash,indicates TD parameter is ready  to be set; 
• Press (or press and hold) button to change the value to 5; 
• Pressbutton 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

Temperature Setting - TCH, TS, TD Cooling mode (TCH = C)

1. 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;
2. 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 = s•c, as shown in Fig. 8.

Heating mode (TCH = H)

1. 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;
2. 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 = 1s0c, TD = s·c. as shown in Fig. 9.

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.

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 WORl<1 socket is not affected. 

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). 

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. 

Humidity Settings - HOH, HS, HD 

Dehumidifying mode (HOH= D) 

1. 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; 
2. 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

1. 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;
2. 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= 5O%RH, HD= 10%RH, as shown in Fig.11.

Humidity Protection Delay- HPT

WORK2 is a humidity socket and the time interval from its power-off 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. 

Humidity Alarm High Limit - HAH, HAL 

1. 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; 
2. 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 humidity is back to the normal humidity range; or press any button to mute the alarm. During the humidity alarm high limit, the output of the WORK2 socket is not affected. 

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). 

Continuous Operating Time - COT 

During humidity control, when COT and output conditions are met, the W0RK2 socket will work in on-off-on-off .... mode. COT is time on as well as time off. eg, if COT =10, the WORK2 output socket will turn on for10 minutes and off for 10 minutes, then repeat. 
When COT= 0 and output conditions are met, the WORK2 output socket will not be affected by COT. 

Backlight Time - BL 

BL is the screen display time. When BL= □ indicates display is always on.
