HOW TO SEE THE SET POINT :
1) Push and immediately release the SET key, the set point will be showed and the “ ”LED
starts lighting ;
2) Push and immediately release the SET key or wait about 15s to return to normal visualisation.
HOW TO CHANGE THE SET POINT :
1) Push the SET key for more than 2 seconds to change the set point value ;
2) The value of the set point will be displayed and the “set ”LED starts lighting ;
3) To change the Set value press the ▲or ▼ within 15s ;
4) To memorise the new set point value push the SET key again or wait 15s.
HOW TO CHANGE A PARAMETER VALUE :
To change the parameter’s value operate as follows:（first level Pr1）
1）Enter the Programming mode by pressing the SET+ ▼keys for 3s , the “set”LED starts to light ;
2）Select the required parameter. Press the SET key to display its value ;
3）Use▲or ▼to change its value ;
4）Press SET to store the new value and move to the following parameter ;
5）To exit : Press SET+▲or wait 15s without pressing a key .
HIDDEN MENU（the second level Pr2）
(The hidden menu includes all the parameters of the instrument (Pr1 and Pr2))
1) Enter the Programming mode by pressing the SET+▼keys for 3s the”set “LED starts to light ;
2) Then push again the SET+▼ keys for more than 7s. The L2 label will be displayed immediately
followed from the Hy parameter ;
3) Select the required parameter ;
4) Press the SET key to display its value ;
5) Use ▲or ▼to change its value ;
6) Press SET to store the new value and move to the following parameter ;

MANUAL DEFROST
Press to view the current evaporator sensor measured temperature value.
Push the key for more than 2 seconds and a manual defrost will start.
8.Output
1 Cooling/Heating :
Cooling :
Normal status : When the cabinet temperature is higher than the set point + hysteresis (Hy),and finish
the Anti-short cycle delay time(AC), cooling will start ;
When the cabinet temperature is lower than the set point, cooling will stop.
For the first time the power on ,and the time up to (od) value , if the cabinet temperature is higher than
the set point + hysteresis (Hy) , cooling will start.
Heating:
Normal status : When the cabinet temperature is lower than the set point , and finish the Anti-short cycle
delay time(AC), heating will start ;
When the cabinet temperature is higher than the set point + hysteresis (Hy), heating will stop.
For the first time the power on ,and the time up to (od) value , if the cabinet temperature is lower than
the set point , heating will start.
If the cabinet sensor is fault , the compressor will run and stop according to the set time.( running
time Cy and stop time Cn).
2 Defrost:
1) If the defrost cycle (id=0) , the defrost will be forbidden .
2) id≠0:
①The Evaporator sensor start to work (P2=y), the evaporator’s sensor temperature is higher than
the defrost termination temperature(dE) , it can’t open the defrost function .
②The Evaporator sensor start to work (P2=y) and the evaporator’s sensor temperature is lower
than the defrost termination temperature(dE) or (P2=n) , the defrost function will start when fit one of the
next conditions :
a) The controller will start defrost according to the set defrost cycle.
b) Press for 2s，start defrost.
3) Under the defrost state（Any of the following conditions can be closed defrosting）:
①The evaporator sensor start to work (P2=y) ,Evaporator sensor temperature ＞Defrost
termination temperature（d7）,defrost is closed
②Maximum time of defrost（Md）runs out，defrost is closed；
③Press for 2s，stop defrost；

1) When the temperature sensor is fault , it is display P1 or P2, it will recover when the problem is
solved.
2) Cabinet over temperature alarm :
When the cabinet temperature is beyond the (AU) set point , Ad and (dA) all finished , it will display
HA, when the temperature is lower than the (AU) , the alarm will stop.
When the cabinet temperature is below the(AL) set point , Ad and (dA) all finished , it will display LA,
when the temperature is higher than the (AL) , the alarm will stop.
9.Hot key
1) Upload
①Program one controller with the front keypad.
②Insert the “Hot key” and push ▲key; the "uP" message appears.
③Turn OFF the instrument remove the “Hot Key”, then turn the controller ON again.
2) Download
①Insert the “Hot key”, push the ▼key, the controller will display “do”.
②Turn OFF the instrument remove the “Hot Key”, then turn he controller ON again.
NOTE: The “Er” message is displayed for failed programming.
In this case push again o key if you want to restart the upload again or remove the “Hot key” to abort the
operation.
★Pelase make sure that the power is stable during this time.

11.Safety rules
★Danger :
1) Strictly distinguish the power wire, relay output, sensor down-lead and data line, and the relay
could not be overloaded.
2) Prohibit connecting the wire terminals without electricity cut-off.
★Warning :
Prohibit using this unit under the environment of over damp, high temp., strong electromagnetism
interference or strong corrosion.
★Notice:
1) The power supply should conform to the voltage value indicated in the instruction, and make sure a
steady power supply.
2) To avoid the possible interference, the sensor down-lead/data line and power wire should be kept in

a proper distance.
3) When evaporator sensor is installed, the sensor should be well connected with the copper tube
which is 5cm away from evaporator inlet.
