1. Use Connect the power supply and equipment, to the controller power supply, as measured temperature is displayed, pre the SET on, the display temperature flashes, pre "+" "-" to set the desired temperature (hold down the on 5 seconds more quickly lift). Ar setting pre SET to confirm return, then the controller according to the set temperature automatically execute the relay off! nbsp 2. Indicator, LED Status Description Indicator: indicates relay is closed, Off means the relay has been disconnected; nbsp Digital: Displays the r 888 is open, follow the instructions to connect the r; Show HHH for the exce 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; nbsp 3. Parameter Function nbsp Pre SET on for 5 seconds to enter the main menu settings, pre the "+" "-" Switching P0-P8, long pre SET to confirm or automatically 10 seconds ar no key operation of the controller to return. nbsp nbsp P0 refrigeration, heating mode: In the main menu interface P0, pre the SET key to enter setup, pre "+" "-" to switch to heating mode [H] [C] for the cooling mode, pre SET to return, long pre SET or 10 seconds without on operation control automatically confirm completion. nbsp [C] under cooling mode: Measured value ge set point + hysteresis, relay; measured value le set point, the relay off; [H] Under heating mode: Measured value le set point - hysteresis, relay; measured value ge set point, the relay off; nbsp nbsp P1 hysteresis setting: In the main menu interface P1, pre the SET on to enter the hysteresis settings, pre the "+" "-" to set hysteresis of 0.1 to 30, pre SET to return ar the completion of a long pre SET or 10 seconds without on operation controller automatically confirm completion. nbsp Cooling mode: When the measured temperature ge set value + return difference, relay, refrigeration starts; when the temperature measured value le set value, the relay off, refrigerator off. For example: the envment 30degC, 25 nbsp nbsp nbsp degC nbsp nbsp nbsp nbs set, hysteresis is set to 2 nbsp nbsp nbsp degC nbsp nbsp nbsp , ar power relay closed refrigeration starts, when the cooling to 25 nbsp nbsp nbsp degC nbsp nbsp nbsp , the relay off cooling off, this time due to cooler have disconnected the temperature began to rise, when the set value rose to 27 nbsp nbsp nbsp degC nbsp nbsp nbsp nbsp(set point + return difference) relay closes when the chiller is started again, and so forth loop between the control temperature 25-27 nbsp nbsp nbsp degC nbsp nbsp nbsp . nbsp Heating mode: when the temperature measured value le set value - the difference back, relay, heater start; when the temperature measured value ge set value, the relay is switched off, the heater is turned off. For example: 10 nbsp nbsp nbsp degC nbsp nbsp nbsp nbspenvment for the setting is 25 nbsp nbsp nbsp degC nbsp nbsp nbsp , hysteresis is set to 2 nbsp nbsp nbsp degC nbsp nbsp nbsp , ar power relay closed the heaters, when heated to 25 nbsp nbsp nbsp degC nbsp nbsp nbsp , 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 nbsp nbsp nbsp degC nbsp nbsp nbsp nbsp(set-point - return difference), the relay is closed heater starts again, and so forth cycle to control the temperature between 23-25 nbsp nbsp nbsp degC nbsp nbsp nbsp . nbsp nbsp 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, pre the SET key to enter setup, pre "+" "-" to set up the set temperature (maximum 110), pre SET to return ar the completion of a long pre SET or 10 seconds without on motion controller automatically confirm completion. For example: P2 is set to 60 nbsp nbsp nbsp degC nbsp nbsp nbsp , the highest temperature measured only 60 nbsp nbsp nbsp degC nbsp nbsp nbsp , when the temperature rises to 60 nbsp nbsp nbsp degC nbsp nbsp nbsp , 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. nbsp nbsp 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, pre the SET key to enter setup, pre "+" "-" set the minimum temperature can be set (minimum -50), pre SET to return ar the completion of a long pre SET or 10 seconds without keystroke controller automatically confirm completion. For example: P3 is set to -20 nbsp nbsp nbsp degC nbsp nbsp nbsp , the lowest temperature of -20 nbsp nbsp nbsp degC nbsp nbsp nbsp nbspcan be measured, when the temperature was lowered to -20 nbsp nbsp nbsp degC nbsp nbsp nbsp nbspar, 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. nbsp nbsp P4 temperature correction: When the measured temperature and the standard deviation of temperature or because the user hardware has special needs, you can use this function to correct temperature corrected before correction + = temperature correction effective range of -7.0 to 7.0 (unit nbsp nbsp nbsp degC nbsp nbsp nbsp ). In the main menu interface P4, pre the SET key to enter setup, pre "+" "-" to set the correction value, pre SET to return once completed, long pre SET or 10 seconds without on operation controller automatically confirm completion. For example: Normal display 25 degrees; temperature correction is 0:00 Show 25 degrees; temperature correction display 26.5 1.5 degrees; temperature correction -1.5 23.5 degrees when displayed. nbsp nbsp P5 delay start time (unit: seconds): When refrigeration or heater work required delay can be turned on delay function to protect the life of the equipment. In the main menu interface P5, pre SET key to enter setup, pre "+" "-" Setting the delayed start time (unit: seconds), the delay time in the range of 0-600 seconds, pre SET to return ar the completion of a long pre SET or 10 seconds without on operation controller automatically confirm completion. nbsp Cooling mode: the first power on, if the current temperature ge set value + return difference when the chiller does not start cooling immediately ar the need to run the set delay time to start. Heating mode: the first power on, if the current temperature le set value - the difference between the time back, the heater does not start heating immediately ar the need to run the set delay time to start. nbsp Downtime cooler or heater starts between two adjacent delay start time is greater than the set value, cooling starts immediately. Shutdown cooling or heater adjacent lapse between two starts is le than the delay start time setting, start again ar the need to run chillers complete set delayed start time for the device to start. Delay time is counted down instantly. Delay start is set equal to zero off delay function. nbsp For example: cooling mode set the delay to 60 seconds, if the current temperature ge set value + return difference when the thermostat start delay ar power, ar 60 seconds, turn cooler. When you reach the desired temperature of the refrigerant is stopped, then the start time, the time the cooling starts, if ar a time delay set by the cooler work immediately or to wait for the end of the timer to work. nbsp P6 Buzzer switch (this function is invalid) nbsp P7 temperature alarm function: In the main menu interface P7, pre SET key to enter setup, pre "+" "-" to set the high temperature alarm temperature setting range is 0-110 nbsp nbsp nbsp degC nbsp nbsp nbsp nbspor OFF to turn off this feature (factory default is 50 nbsp nbsp nbsp degC nbsp nbsp nbsp ). Upon completion pre SET to return, long pre SET or 10 seconds without on operation controller automatically confirm completion. When the temperature reaches the set value of the high temperature alarm, digital display - - - simultaneously forced off the relay. When setting has been preing "-" key, the setting value is reduced to 0, then click the "-" key to display "OFF", at which time the function is off, the high temperature alarm function is invalid. nbsp P8 restore factory settings: Some man-made causes internal thermostat setting confusion, one by one to set the time-consuming, then use this function to restore the factory settings.
In the main menu interface P8, pre SET key to enter setup, pre "+", "-" is set to [H], pre SET to return ar the completion of a long pre SET or 10 seconds without on operation controller automatically confirm complete recovery factory settings. (Another way: In the off state, while holding down the "+" and "-" on, then on, all of the above back to factory default settings.)
