Product internal parameter descriptions and settings
Panel buttons: set (set key) + (up key) - (down key)
1。temperature control point setting method:
Under normal operation, press the set key, shows the number of beats, then display the value of the temperature setting: Press the + or - key to increase or decrease the temperature setting. Long press + or - to quickly increase or decrease. No keystrokes automatically after 5 seconds to save the settings and return to normal operation.
2。the cooling and heating mode selection method
Set key set key 5 seconds to enter the menu screen display P0 + can enter the set - you can switch to the P0, P1, P2, P3, P4, P5, and this time show the main menu, press again to set change the setting to 10 seconds automatically identify and return to normal operation
P0 refrigeration, heating mode
Cooling mode: When the temperature measurement value ≥ temperature set point, the relay pull cooler start; refrigeration relay is switched off when the temperature measurement value Heating mode: When the temperature measurements> Temperature set point + hysteresis, the relay is switched off, the heating is turned off; relay is energized when the temperature measurement value ≤ temperature set point, the heating, the heating starts.
P1 hysteresis setting
Cooling mode: When the temperature measurement value ≥ set value, the relay, refrigeration starts; For example, set the value of 20 ° C environment for 30 ° C, back to poor set 2 ° C on power relay closes cooler start, when refrigeration to 17.9 ℃, relays disconnect the cooler off, this time due to the cooler been disconnected temperature began to rise when the rebound to set the value of 20 ° C, the relay is closed refrigeration start again, and so forth loop to control the temperature not higher than 20 ° C
Heating mode: When the temperature measurement value ≤ settings and relay heater starts; When the temperature measurement value> settings + return difference, the relay is switched off, the heater is turned off. For example, set the value of 30 ° C environment for 20 ° C, back to poor set 2 ° C, the heater relay is closed after power-on start relay to turn off the heater off when heated to 32.1 ℃, this time due to heater has disconnected the temperature begins to fall immediately down to set the value of 30 ° C, the relay closes heater started again, and so forth cycle to control the temperature of not less than 30 ° C.
P2 is the lowest temperature setting lower limit:
Limited to the minimum temperature set point of the thermostat control setting range.
For example: Set the -10 temperature set point minimum can only be set to -10 if you want to expand the temperature range of the temperature set point, you need to adjust the upper and lower setting.
P3 highest temperature setting caps:
Limit the maximum temperature set point control thermostat setting range.
For example: set to 60 temperature set point of the highest can only be set to 60 if you want to expand the temperature range of the temperature set point, you need to adjust the upper and lower setting.
P4 temperature correction
This feature can be used when the measurement of the temperature deviation and standard temperature correction, the corrected temperature = temperature + correction value before correction
P5 delay start time: minutes
Cooling mode: the first power, current temperature ≥ set value, the cooler will not immediately start cooling, need to run to set the delay time to start.
Heating mode: the first power, if the current temperature ≤ settings, the heater will not immediately start the heating, the need to run set delay time to start.
The down time between the start of the refrigeration or heater between two greater than the cooler immediately start the delayed start time setting;
Refrigeration or heater adjacent downtime between the two starts after a lapse of less than delay start time setting cooler, cooler start need to run the finished set delay start time setting the device to start . The delay time from stop instantly.
