12V /24V High Quality STC1000 Temperature Controller

STC-1000 temperature controller regulates the temperature by turn on/off the connected load; Within dual separate relays, the heating and the refrigeration controlling modes auto switch according to the room sensor temperature; that’s why It was called “All-Purpose Temperature Controller.

STC-1000 Features

• Classic & Best-selling from 2005, a lot of DIY videos available on YouTube;
• The temperature set-point and the hysteresis to determine the ideal temperature range;
• Adjustable Temperature Calibration;
• Programmable Protection Delay Time helps to extend the life of loads;
• Alarm by error code on display, and the buzzer screams once the sensor temperature is over the measurable range or sensor error.
• Embed NVM to auto memory exists parameters, resume all data once power back, need not configure it again.

Two independent relays within STC-1000, one wiring a heating unit and the other connected to a refrigeration unit. The controller will auto switch between heating and cooling modes. That is why it was called “All-purpose temperature controller.”

STC-1000 Wiring Diagram

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.

• 1 & 2 terminal for input power, max no more than the marked voltage* 110%, e.g. 220 v * 110% = 242 V.
• 3 & 4 terminal for NTC Sensor cable probe, Need not to distinguish + or – ;
• 5 & 6 terminal for the heater, Wiring the 5 to a live line, and terminal 6 to a heater, or opposite; In other words 5 and 6 together like a power switch;
• 7 & 8 terminal for Cooler, Wiring the 7 to a live line, and terminal 8 to a heater, or opposite; In another word 7 and 8 together like a power switch;

How STC-1000  temperature controller works?

In essence, this unit STC-1000 is just a switcher with the below conditions:

Temperature condition

There is a Temperature Setting Value (Set-Point) and a Hysteresis/Difference Value in the configuration interface. Both are editable, and these two data decide the Ideal Temperature Range.​

Time Condition

There is a Delay Time Value (option from 1 to 10 minutes) to protect the compressor from start-stop frequently; it is count time from the moment the compressor stops last time; The relay to refrigeration machine without electricity before the instant time passes this Delay Time.​
