How to set the target temperature range?

The temperature range was defined from “SP” to “SP + Difference (Hysteresis)” in this unit.

• SP means the Temperature SetPoint; it is the lower limit in this controller;
• The “SP + Hysteresis” result is the upper limits (Hysteresis is a unidirectional parameter here).
• From SP to “SP + Hysteresis” is the range user wishes temperature to keep around; once exceeds this range, the status of the load will change; follow the below steps to set it:
  • Press the “SET” key, which shows the SP value;
  • Press the “UP” and “DOWN” keys to change SP, which F2 and F3 are limited;
  • It will back to normal status in the 30s if without operation.

How to configure the other parameters of STC200+?

1. Hold the “SET” and the “Up”  keys for 4s simultaneously to enter the function code interface; you will see F0.
2. Press the “UP” or “DOWN” keys to select the code you want to update;
3. Press the “SET” button to check the existing value;
4. Press the “UP” or “DOWN” keys to adjust data;
5. Press the “SET” key again to the function menu, and the configured value is saved.

More Tips:

• Repeat Steps 2 / 3 / 4 to adjust other parameters;
• Press “SET” for 3s to save data and back to normal monitor status.

How to take it as the refrigerator temperature monitor and alarm?

• Set the F4= 3;
• The external alert will be triggered once found the room temperature crosses the safe range (SP+Hysteresis and SP);
• As a room temperature monitor system with a built-in alarm and external alarm supportable, it is suitable for both the freezer room and the warm room; but it will not control the refrigerator or the heater;
• It could be used as the exhaust temperature monitor/alarm unit for aquarium/fish tank water, chest/upright freezer, server room, spa room, smoking room, wine cellar, etc.
