4.4. Wiring Diagram
A. Need not to distinguish + or - when wiring the NTC sensor's cable or the Input power.
 Wiring the 5 to the live wire and terminal 6 to a heater, or the opposite.
 Wiring the 7 to the live wire and terminal 8 to a refrigerator, or opposite.
The heating and cooling mode will switch automatically.
B. The input voltage must be within the voltage value marked in the diagram ±10% value.
C. Load Wattage ≤
Load Voltage ∗ Max Current of Relay
Power Factor
 The factor for Inductive Load like compressor, motor, 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 lamps is usually nearly 15.
5. Configurations
5.1. Code and Function Menu
Hold the button for 3s to enter the menu list .
Code Function Min Max Default Unit
F1
Temperature Setpoint -50.0 99.9 10.0 °C
F2
Temperature Hysteresis / Return Difference 0.3 10.0 0.5 °C
F3
Protection Delay Time for Refrigerator 1 10 3 Min
F4
Temperature Calibration -10.0 10.0 0 Hour
F1: Temperature Setpoint
It is the room temperature value users wish to keep around.
F2: Temperature Hysteresis / Return Difference Value
A. Switch to heating mode once found
Measured Temperature ≤ Temp Set-point – Return Difference
B. Switch to Refrigeration mode once found
Measured Temperature ≥ Temp Set-point + Return Difference
But the compressor will not start up until the compressor's delay time is over.
F3: Compressor Delay Time: The purpose of this value is to protect the compressor.
F4: Temperature Calibration
F4 = Real Temperature – Measured Temperature
5.2. How to Set Parameters?
Step1:
Hold the for 3s to enter the menu list; the display shows the code
F1
Step2:
Press the or to select the code you want to update;
Step
3:
Press
the to check the current value.
Hold the and press or key to change the value;
Step
4:
Release
keys to back to function menu list.
Repeat operation from Step 2 / 3 / 4 to adjust other parameters;
Step5:
After
configuring all values, remember to press the for saving data, and back to
normal monitor status
, the display shows the room sensor temperature.
T
he modified value will be discarded and back to normal status if without operation
in 8 seconds.
5.3. When Will is the Load Works/Stops?
Loads
Startup Condition
Stop Condition
Refrigeration
Room Temp ≥
F1
+
F2
and
The instant period passed the delay time (
F3
)
Room Temp ≤
F1
Heating
Room Temp ≤ F1 - F2
Room Temp ≥ F1
 Room Temp: Measured temperature value by the controller's sensor.
 F2: Return difference Hysteresis.
 The instant period is counts from load stops last moment to the instant time;
In other words, the time should be later than the compressor's last stops moment + delay
time.
6. Error & Solution
When an alarm occurred, the buzzer scream "di-di-di," press any key to stop screaming; but the
error code on display will not disappear until all the failures are resolved
Code Reason Troubleshooting
E1
The memory unit broken
Press/key to restoring the default data or get factory reset.
EE
Sensor error
Ensure the sensor was installed firmly or replace a new
sensor, display back to normal in 10 seconds once the
problem is fixed.
HH
Room temp. > 99.9°C
Check the room temperature and all loads, then stop the loads
from working manually if necessary.
