Panel thermostat module with probe, 12VDC power supply, which can be set according to both cooling and heating.
It supports temperature calibration to correct any discrepancies between the displayed temperature and the real one.
Alarm function for the temperature exceeding the set threshold and light indicator to display the active state.
Dual display showing the detected temperature ( PV ) and the set temperature ( SV ).
It has the function of memorizing the settings in case of power failure.

Use:
When starting, the module displays the measured temperature.
Short press on SET the display flashes, press up and down until the desired temperature is set. After setting, press SET to confirm. In this step, the module will automatically control the relay to maintain the set temperature.
The red indicator indicates the start-up delay when it blinks and when it lights up it indicates the relay is closed.
Pressing the SET button for 5 seconds enters the program selection menu. Another 5-second press of the SET button or inactivity for 10 seconds confirms the selection.
Code table:
| Code | Function | Interval Set | Default |
| P0 | Heating/Cooling | H/C | C |
| P1 | Returns the difference | 0.1-30 | 2 |
| P2 | Set limits to maximum | 120 | 120 |
| P3 | Set limits to minimum | -55 | -55 |
| P4 | Temperature correction | -20 | 0 |
| P5 | Start delay | 0-10 min | 0 |
| P6 | Temperature Alarm | -175 | OFF |
| Q7 | Save settings | ON/OFF | OFF |
| P8 | Return to factory settings | ON/OFF | OFF |
Installation:
Programs:
P0: Cooling/heating mode. Select program P0, press SET to confirm, arrow for H (heating) or C (cooling) mode, SET again for 5 seconds to confirm or leave 10 seconds without operation. In cooling mode, when the measured temperature value is greater than or equal to the temperature reference point, the relay is closed. When it is lower than the reference point minus the return difference, the relay is open. In heating mode, when the measured temperature value is lower than or equal to the temperature reference point, the relay is closed. When it is greater than the reference point plus the return difference, the relay is open.
P1: For example, if the environment is 30°C, the set value is 25°C, and the hysteresis is set to 2°C. After the power is turned on, the relay closes the refrigerator to start. When the cooling reaches 23°C, the relay stops the refrigerator and the refrigerator is turned off. The open temperature starts to rise. When it rises to the set value of 25 °C, the relay closes the refrigerator again, so that the control temperature of the repeated cycle does not exceed 25 °C.
P2: the thermostat has the upper limit function of the highest setting, which limits the setting range of the highest temperature reference point controlled by the thermostat.
Press and hold SET for 5 seconds to display P0, press the arrows to switch to P2, press SET once to set the upper limit, press the arrows to set the highest settable temperature, the maximum value is 110, press SET once after completion.
For example: the set temperature value set to 60 can only be set to 60°C. If the set temperature value needs to be extended, the set value of the upper limit must be adjusted first.
P3: Same function as P2, but for the lower temperature limit.
P4: Temperature correction is necessary when the displayed temperature value does not correspond to reality.
P5: Set the start-up delay time in minutes to protect the controlled equipment.

E ok aparatul, arata cu 2-3 grade mai mult decat temperatura normala dar poate fi programata diferenta de temperatura.
