1. Use Connect the power supply and equipment, to the controller power supply, as measured temperature is displayed, press the SET button, the display temperature flashes, press "+" "-" to set the desired temperature (hold down the button 5 seconds more quickly lift). After setting press SET to confirm return, then the controller according to the set temperature automatically execute the relay off! 2. Indicator, LED Status Description Indicator: indicates relay is closed, Off means the relay has been disconnected; Digital: Displays the sensor 888 is open, follow the instructions to connect the sensor; Show HHH for the excess of the maximum temperature of the measuring range, the thermostat will be forced off the relay; Display L L L of the measuring range of the lowest temperature, the thermostat will be forced off the relay; Display - - - high temperature alarm, thermostat will forcibly disconnect relay; 3. Parameter Function Press SET button for 5 seconds to enter the main menu settings, press the "+" "-" Switching P0-P8, long press SET to confirm or automatically 10 seconds after no key operation of the controller to return. P0 refrigeration, heating mode: In the main menu interface P0, press the SET key to enter setup, press "+" "-" to switch to heating mode [H] [C] for the cooling mode, press SET to return, long press SET or 10 seconds without button operation control automatically confirm completion. [C] under cooling mode: Measured value set point + hysteresis, relay; measured value set point, the relay off; [H] Under heating mode: Measured value set point - hysteresis, relay; measured value set point, the relay off; P1 hysteresis setting: In the main menu interface P1, press the SET button to enter the hysteresis settings, press the "+" "-" to set hysteresis of 0.1 to 30, press SET to return after the completion of a long press SET or 10 seconds without button operation controller automatically confirm completion. Cooling mode: When the measured temperature set value + return difference, relay, refrigeration starts; when the temperature measured value set value, the relay off, refrigerator off. For example: the environment 30C, 25 C is set, hysteresis is set to 2 C , after power relay closed refrigeration starts, when the cooling to 25 C , the relay off cooling off, this time due to cooler have disconnected the temperature began to rise, when the set value rose to 27 C (set point + return difference) relay closes when the chiller is started again, and so forth loop between the control temperature 25-27 C . Heating mode: when the temperature measured value set value - the difference back, relay, heater start; when the temperature measured value set value, the relay is switched off, the heater is turned off. For example: 10 C environment for the setting is 25 C , hysteresis is set to 2 C , after power relay closed the heaters, when heated to 25 C , the relay off the heater turned off, this time because the heater has been disconnect the temperature began to fall, down to the current set point 23 C (set-point - return difference), the relay is closed heater starts again, and so forth cycle to control the temperature between 23-25 C . P2 highest temperature setting limit: To avoid misuse of others led to the set temperature is too high risk, the highest setting of the thermostat capping defining the control thermostat setting range maximum temperature set point. In the main menu interface P2, press the SET key to enter setup, press "+" "-" to set up the set temperature (maximum 110), press SET to return after the completion of a long press SET or 10 seconds without button motion controller automatically confirm completion. For example: P2 is set to 60 C , the highest temperature measured only 60 C , when the temperature rises to 60 C , the digital tube displays "H H H", the relay forcibly disconnected. If you want a higher temperature set point temperature to expand the scope, you need to adjust the upper limit set value. P3 set minimum temperature limit: To avoid misuse of others lead to the occurrence of ice blocking temperature is too low, the lowest of the thermostat set lower limit function, defining the scope of the thermostat setting controls the minimum temperature set point. In the main menu interface P3, press the SET key to enter setup, press "+" "-" set the minimum temperature can be set (minimum -50), press SET to return after the completion of a long press SET or 10 seconds without keystroke controller automatically confirm completion. For example: P3 is set to -20 C , the lowest temperature of -20 C can be measured, when the temperature was lowered to -20 C after, LED displays "L L L", the relay forcibly disconnected. If you want to lower the temperature set point temperature to expand the scope, you need to adjust the setting value lower limit. P4 temperature correction: When the measured temperature and the standard deviation of temperature or because the user hardware has s
