HOW TO USE:
Connect the power supply and equipment, the controller can be powered to measure the temperature is displayed, press the SET button, the display temperature flashes, press + - to set the desired temperature, after setting finished, press SET to confirm the return, this When the controller automatically executed by setting the relay off. The thermostat 20A relay outputs to meet a variety of high-power loads, connect the control circuit can be powered for the thermostat, then the display shows the ambient temperature.
LEDs, LED and buzzer status descriptions:

Digital Tube: Shows LL sensor opens, follow the instructions to connect the sensor; display HH is beyond the measurement range thermostat will forcibly disconnect relay; high-temperature alarm display ---
FUNCTION PARAMETERS:
Press SET 5 seconds to enter the main menu settings, press the + - Switch P0 ... P6, or long press the SET button for 10 seconds without motion controller automatically confirm return.
P0 refrigeration, heating mode:
Press SET 5 seconds display P0, press SET to set the operating mode, press the + - switched to heating mode [H] [C] for cooling mode press SET to return, long press SET or automatic confirmation button for 10 seconds without motion controller carry out.
Cooling mode: when the temperature measured value ≥ temperature set point relay refrigeration, refrigeration starts; when the temperature measured value ≤ temperature set point - hysteresis, the cooling relay is off, the cooling off.
Heating mode: when the temperature set point temperature measurement value ≤ heating relay, heater starts; when the temperature set point temperature measurements ≥ + when hysteresis heating relay is off, the heater is turned off.
P1 hysteresis setting:
Press SET 5 seconds display P0, press + - Switch to P1, press SET to set back the difference, press + - to set hysteresis 0.1 to 15, press SET to return after the completion of, or long press the SET button for 10 seconds without motion controller automatically confirm completion.
Cooling mode: When the temperature measurement value ≥ set value, the relay, refrigeration starts; when the temperature measured value ≤ set value - the difference between the return, the relay off, cooling off.
Such as the environment is set at 30 ℃ 25 ℃, hysteresis is set to 2 ℃, after power relay closed cooling starts, when cooling to 23 ℃, the relay off cooling off, this time due to the cooler has been broken Open the temperature began to rise back up to the set value when 25 ℃, the relay is closed cooling starts again, so repeated cycle control temperature no higher than 25 ℃.
Heating mode: When the temperature measurement value ≤ set value, the relay, the heater starts; when the temperature measured value ≥ set value + return difference, the relay off, the heater is turned off.
Such as the environment is 10 ℃ setting is 25 ℃, hysteresis is set to 2 ℃, the relay is closed after power heater starts, when heated to 27 ℃, the relay off the heater turned off, this time due to the heater has been broken Open the temperature begins to drop, the moment when the set value dropped 25 ℃, the relay is closed heater starts up again, so repeated cycle control temperature not lower than 25 ℃.
P2 limit the maximum temperature settings:
To avoid misuse of others led to the setting temperature is too high risk that the thermostat is set to a maximum limit function, define the scope of the thermostat setting to control the maximum temperature set point.
Press SET 5 seconds display P0, press + - Switch to P2, press SET to set the maximum limit, press + - to set up the set temperature, the maximum is 110, according to a SET return is completed, long press SET or 10 No keystrokes second controller automatically confirm completion.
For example: Set the maximum temperature set point is 60 to 60 ℃ can only be set if you want a higher temperature set point temperature to expand the scope, you need to adjust the upper limit setting.
P3 lowest temperature setting limit:
To avoid misuse of others lead to the occurrence of ice blocking temperature is too low, this thermostat has a lower limit on the lowest setting function, defining a set range of the lowest temperature control thermostat set point.
Press SET 5 seconds display P0, press + - Switch to P3, press SET to set a minimum limit, press + - to set the minimum temperature can be set to a minimum value of -50, press SET to return after the completion of, or long press SET 10 seconds, the controller automatically confirm no keystrokes to complete.
For example: Set the minimum temperature set point 2 can only be set to 2 ℃ temperature set point if you want to expand the scope of lower temperatures, you need to change the setting lower limit.
P4 temperature correction:
When measuring the temperature and the standard temperature deviations due to user hardware or have special needs, you can use this function to correct temperature = temperature correction after correction + correction before the effective range of -7.0 to 7.0.
Press SET 5 seconds display P0, press + - Switch to P4, press SET to correct, press + - to set the correction value, press SET to return upon completion, or long press the SET button for 10 seconds without motion controller automatically confirm completion .
For example, the normal display is 25 degrees; temperature correction display 25 is 0 degree; temperature correction is displayed 26.5 1.5 degrees; temperature correction is displayed -1.5 23.5.
P5 delayed start time (unit: min):
When the cooling or heating needs work delay, delay function can be opened to protect the life of equipment.
Press SET 5 seconds display P0, press + - Switch to P5, press SET to set the delay start time is in minutes, press the + - Set 0-10 minutes, press SET to return after the completion, or 10 seconds long press SET No keystrokes controller automatically confirm completion
Cooling mode: the first powered, if the current temperature ≥ set value, the cooler will not start cooling immediately after the set delay time required to run start.
Heating mode: the first powered, if the current temperature ≤ set value, the heater will not start heating immediately after the set delay time required to run start.
When downtime cooler or heater starts between two adjacent delay start time is greater than the set value, the cooler starts immediately.
Shutdown cooling or heating between two adjacent launch delayed start time lapse is less than the set value, the need to start again after finished running cooler set delayed start time for the device to start. Delay time is counted down moments.
For example, the state set the delay under refrigeration for 5 minutes after boot cooler startup delay, five minutes after opening the refrigerator to reach the desired temperature when cooling is stopped, then the start time, the next time the refrigerator immediately start the timer is complete work unfinished end timing to wait timed to work, delay in the LED blinks.
Delay start is set to 0 equals off delay feature.
