6.3. Wiring Diagram
A. 10K NTC sensor, Need not to distinguish + or - when wiring it.
B. The input voltage must within the voltage value marked in diagram ±10% value.
C. Load Power ≤Voltage of load ∗Max current of Relay
Factor
The factor for Inductive Load like compressor, heating pump, usually be 5~8;
The factor for Resistive Load like Electric heating rod, Electric blanket
usually is 1.5~2;
The factor for Incandescent lamp usually is 15.
7. Configurations

HC Heating or Cooling C H C
D Return Difference (°C) 1 15 5 1
LS Lowest set Limit (°C) -50 ATV
-50 1
HS Highest Limit (°C) ATV 120 120 1
Temperature Calibration (°C)
Delay Time (Min)
7.2. What is ATV and how to set it?
ATV means Aim Temperature Value which is the ideal temperature you wish to reach,
once exceed this value (if difference value = 0) the status of load will be changed,
Details of setting as follow
Step1
Assure power on, Press and release key once times you will find display
blink a data which is changeable.
Step2
Now press the or keys to get you aim value;
press and hold on the or is fast forward function;
the steps length is 0.1°C;
The editable range between lower (LS) and higher (HS) limit.
The buzzer will scream once Room Temperature < LS
, or Room
Temperature > HS, Press any key to stop screaming if you want to.
Waiting for 10s the device will save data automatically or press to save it.
7.3. When will the load working?
Firstly of all, the instant time passed the delay time (PT), and then matches one of the following
A. In heating mode (
=
), the relay will turn on heater when
Measured Temperature Value ≤ATV - Temp. Differential (D)
B. In cooling mode (
=
), the relay will turn on cooler
Measured Temperature Value ≥ATV +Temp. Differential (D)
7.4. How to correct measured temperature if found it not right?
Exist gap/distance between the measured temperature and the real temperature is normal
especially the first time launch this controller; the gaps could be corrected by setting the value in
CA, and please follows the formula: CA= Real Temperature-Measured Temperature.
7.5. How to set other parameters?
Press and hold on until appears the code HC (nearly 3s).
Now press the or keys to select the code you want to update;
Press and release to see exist value; then press the or to get your aim value;
Press key to memorize the configured value and return to the menu.
Repeat operation from Step 2 / 3 / 4 to adjust other parameters;
ress to save data and quit from setting mode back to normal monitor status. r let it
alone, the modified value will be saved automatically if without operation in 10s
7.6. How to get Factory Reset?
In normal status, press and keys in same time, do not release them until screen shows
YS which means success, nearly 3s.
8. Error & Alarm
When alarm occur, if the readout flash ---and buzzer sounds,
A. Press any key to stop buzz scream;
B. Check the room temperature and then change the compressor / heater working
status manually if necessary,
C. fix or replace the sensor; after that screen will back to normal state
D. And other code please, reference below content to fix problem.
Code Reason Troubleshooting
HHH Measured temperature >
Check the room temperature and then change the
compressor / heater working status manually if
LLL Measured temperature <
