How do you set the target temperature range? The range was defined from “SP” to “SP + Difference” in this unit.
- SP means the Temperature SetPoint, and it is the lower limit in this controller;
- [SP + Hysteresis] is the upper limit (Hysteresis is a unidirectional parameter here).
- From SP to [SP + Hysteresis] is the range the user wishes temperature to keep around, once exceeds this range the status of the load will be changed, 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 LS and HS limited;

- Release all keys, and then press the “UP” or “DOWN” key to the next code;
More Tips:
- Repeat Steps 3 / 4 to adjust other parameters;
- All new data will be auto-saved, and it will back to normal status in 4s if without operation.
