Third, the panel operation 

     1, temperature control (shutdown temperature) adjustment: press the set button flashes to control the temperature, press  or  key to change the value and memories. Hold down the key and  button and hold for more than 2 seconds to quickly increase or decrease the value. Press the set button to exit adjust status display cabinet temperature; If you do not press any key, the display cabinet temperature recovery after six seconds. (Control of temperature adjustment range: Parameter E 1 ~ parameter E 2) 

2, cooling indicator: refrigeration process, refrigeration lights; constant temperature refrigeration lights off; delay the process, refrigeration lights flashing. 

3, the heating indicator: the heating process, heating lights; constant temperature heating lamp; delay the process, heat lamp blinks. 

4, parameter settings: 

· Press the set button for six seconds after entering the parameter setting, while flashes E 1; 

· Press the key to change the parameter set selection, order display E 2, E 3, E 4, E 5, C1, C2, E 1; 

· Press the or  key to display and modify the value of this parameter, the stored data; 

Not press any key within six seconds to return to normal operation.


5 , restore the factory settings : hold down down key for one second , and then hold down the up key six seconds , the display flashes. At this point all parameters restored to factory default , six seconds after the return to normal operation.

  6 , parameter lock : Press the down key for six seconds , flashing "OFF" means locked, "ON" indicates unlocked. Lock

      After setting the parameters , the parameters can only view can not be changed . Controlled temperature regulation is still valid. ( Factory default "O N")

Fourth, the functional description

1, the cooling control:

   · Temperature control mode ( parameter C2) is set to 0 , the compressor after a delay , when the cabinet temperature is greater than ( control temperature + temperature difference ) ,

     Compressor starts , cabinet temperature is less than the control temperature, the compressor stops.

   · To protect the compressor , the compressor stops every time must exceed the delay time (E4 parameters ) can be re- started.

2 , the heating control

   · Temperature control ( parameter C2) is set to 1 , the delay through the heater , when the cabinet temperature is lower than ( the control temperature - temperature difference ) , the heater starts heating cabinet temperature greater than the control temperature, the heater stops heating .

3 , non- normal operating mode :

   · Cabinet temperature probe short circuit or high temperature gauge ( greater than 120 °C / 248 ° F) display "HH"; cabinet temperature probe open or low overrun ( less than -45 °C / -41 ° F) to display "LL". Warning lights flashing.

V. Installation Precautions

1 , in order to prevent high-frequency interference , the probe line in conjunction with power lines or bundle of parallel control lines to separate wiring .

2 , such as the installation need to extend the probe lines up to 100 meters , is not subject to re- examination.

3, the thermostat can not be installed where there is dripping .

Sixth, the thermostat matching accessories

1 , a temperature probe

2 , a mounting bracket

3 , a baffle and ¢ 3 * 10MM screw 1 .
