5. How to calibrate the air probe 
If the actual cellar temperature differs from the displayed temperature,  set ot = 
actual cellar temperature minus displayed temperature. 
6. How to adjust defrost cycle 
1) In case the cooling unit does not stop, the parameters FnC = C-n, idF =4 and 
MdF = 30 can be used to cycle off. 
2) In case there is excessive frost, the parameters FnC = C-y, idF = 6 and MdF = 
20 can be used to avoid frost. 
7. How to adjust the humidity 
The parameter Fon is used to adjust the humidity in the wine cellar. Higher Fon 
results  in  higher  relative  humidity. Use  a  separate  hygrometer  to  monitor  the 
humidity. 
8. How to set alarm call 
1) A speech notice will be sent to your phones when the cellar temperature is 
higher or lower than the set-point Set by ALU or ALL. 
2) In order to test the call function, set parameters Ald = 0 and dAO = 0.  After 
testing, set Ald = 60 and dAO = 23. 
9. How to set low temperature cellar heater 
The heater turns on  at set-point SAA minus regulation differential Shy;  the 
heater turns off at heater set-point SAA. 
NOTES: 
  Use a forced air heater to warm up the wine cellar. 
  If there is a thermostat on the heater, bypass it or set the thermostat at the 
highest level. 
  If the heater runs more than 10 A current, use a 120VAC coil contactor. 
10. Manual Defrost 
Press the DEF key for more than 2 seconds and a manual defrost will start. 
11. Parameter Programming 
1) Press the SET +  keys for more than 3 sec until the “°C” or “°F” LED starts 
blinking, then release the keys. 
2) Press again the SET +  keys for more than 7sec until the Pr2 label will be 
displayed, then release the keys. The first parameter Hy will be displayed.
