Custom defrost temperature Controller Manufacturer STC-8080H

STC-8080H refrigeration defrosts thermostat from China Manufacturer is a high-low limit temperature controller within 2 output relays.

Features 

• The lower limit and the upper limit determine the ideal temperature range, from -40 to 50 ℃; Set them directly by shortcut key;
• Embed NVM to auto memory exists parameters, resume all data once power back, need not configure it again;
• Adjustable Temperature Calibration;
• Control the refrigeration by temperature and editable delay time; the compressor works 15mins and stops 30 mins once found sensor error;
• Control the defrosting by time and the artificial forced-defrosting available;
• Alarm by error code on display, and the buzzer screams;
• Control the alarm by temperature and editable delay time.

Wiring Diagram of STC-8080H refrigeration & defrost Thermostat

Tips:

• The NC is a close point normally, it will open when the load is working, not means "always close point" as some temperature controller factories marked, please do not misunderstand this term.
• This unit does not output AC electricity; hence you have to wire all live and null wires to each port; you may use the jumper wire conveniently.

This controller offers two extra options more than the STC-8080A+ refrigeration defrost controller. They are the editable delay time for the compressor and the alarm delay time setting.

How to set the temperature?

The aimed temperature range was defined from “F1” to F2”; you need to set both.
≥ F1, refrigeration starts.
≤ F2, refrigeration ends.

Operates

1. [SET] key for 3s, and the code F1 will appear.Hold the

2. Press the [Up] or [Down] key to get the aim function you want to update;

3. Press the [SET] key to check the existing value; Hold the [SET] key meanwhile press the [Up] or [Down] key (composite key) to change the value;

4. Release all keys once it reaches your aim value; Repeat operation from Step 2 / 3 / 4 to adjust other parameters;

5. After configuring all values, press the [RST] key to save data and back to normal monitor status. Attention: the modified value will be saved automatically and back to normal status if without operation in 30 seconds.
