STC-3008 dual temperature controller with red blue display and two probes

Here is another good temperature control and monitoring device STC-3008 integrates two single themperature controllers in this article you will learn how to connect and set ,price and where to buy it, my review.

Here is pros :

  • Two two independent temperature controllers in one case
  • Red and Blue display
  • Two relay a two probes
  • Same size as other temperature controllers (for example as MH1210W)
  • Have alarm function and delayed start in min
  • Al values can set 0.1°C
  • Cheap a this price

Here is cons:

  • Nothing comes to mind two integrated temperature controller for 10 usd is very cheap

My verdict:

The STC-3008 is a valuable thermostat because at a cost of around 10 usd it gets two universal thermostats in one box. Each thermostat unit can be used separately for cooling or heating.Accuracy is very good to improve it by 0.1°C step calibration. STC-3008 has added  alarm function  and relay delay in minutes. The connection is similar to other temperature controller as Mh1210W, SHT-2000  more below in the manual…

Its good for hatcheries, terrariums, refrigerators, compressors, for controlling in 2 steps.

 

 

 

 

Diagram schematic and manual + video

In the rows below I will show you how to connect the STC-3008 as you set it to cool or heat + other functions.Maybe help with the setting my video on youtube – I show there how to set the STC-3008 thermostat for cooling and also for heating:

Heating/cooling mode setting


Setting mode: setting (starting temperature): Press and hold the ▲ button to start the temperature flashing. Use ▲▼ key to set the starting temperature value.
Tips
Setting method: Start value <stop value (program automatically determines working mode is heating mode)

Setting method: Start value > stop value (the program automatically determines the working mode is cooling mode) 

Set startup temperature:

Press the “up ”  arrow button once to display the starting temperature. Long press the “up ” arrow button for about 3 seconds,The required temperature can be set by the up and down keys

Set the stop temperature:

Press the  button arrow  once to display the stop temperature. Long press the arrow  button for about 3 seconds and the stop temperature number flashes. The required temperature can be set by the up and down keys

Example in practice:

Heating use case: control the water heater, heat to 65 ° C to stop, the temperature drops back to 50 ° C and start heating again

The first step: heating mode, starting temperature <stop temperature
Step 2: Press and hold the ▲ button to start the temperature flashing. Use ▲▼ to set the starting temperature to 50 °C.
Step 3: Press and hold the ▼ button to stop the temperature flashing. Set the stop temperature to 65 °C with ▲▼ keys, and the setting is completed!
Refrigeration use case: use in the farm, the fan is ventilated to 26 ° C to stop, the temperature is raised to 30 ° C and the ventilation is started again.
The first step: cooling mode, starting temperature > stop temperature

Step 2: Press and hold the ▲ button to start the temperature flashing. Use ▲▼ to set the starting temperature to 30 °C.
The third step: long press the ▼ button to stop the temperature flashing, set the stop temperature to 26 °C by ▲▼, the setting is completed!

 

Press “Up 1” Button & “Up 2″Button at the same time to setting mode

  1. Attachment

    I have an STC-3028 but it came with no instructions. The 3008 is similar but only thing the blue display is for humidity. It’s displaying HHH and I’m not able to set it. Can you help?

  2. Do you know of a dual temperature controller that will chose a relay if a difference between the two probes is seen? For example, close relay if the temp in room A is greater than room B by 1deg.
