Description: Single Display Temperature Controller Temperature control range: -50 C ~ 99 C Temperature control accuracy: 0.1 C Working power supply: DC12V DC 24V AC110V~220V Sensor: NTC 10K 1 meter (with probe) Product Size: 79.2mm41.9mm26.3mm Hole Size: 72.1mm39.2mm Panel instruction Indicator light status instruction Key operation instruction 1.The way to check parameter: Under normal working status, pre and releasekey once instantly, it display temperature setting value; pre and releasekey once instantly, it displays the difference value. It back to display the normal temperature display status in 2s. 2.The way to set parameter: Under controller normal working status, pre SET key for 3s or more to enter parameter modifying mode, and the SET indicator light on, screen display the first menu codeF1. Pre key to avoid the interference, the sensor down-lead and power wire should be kept a distance or key to page up and page down menu item to find accordingly code, pre SET key to display the parameter set value of the current menu. pre and hold SET key, pre key or key again to adjust up and down the parameter setting value of the current menu item. Pre and hold both SET key and key or key simultaneously to choose and adjust the parameter value of the current menu value promptly. After finishing the setting, pre and release the key instantly to save the parameter modified value and return to display the normal temperature value. If no key operation within 30 seconds, system won't save modified parameter, screen back to display normal temperature. Screen display Er if error appears during parameter saving, and back to normal working status 3 seconds. 3.Restore system data When electrified, system will check itself, screen will display Er if error exit, please pre any key at this time, and it restore default value and enter into normal working mode. It is advised to reset the parameter value under this condition Operation instruction Under controller normal working status, pre and hold key for 3s can turn off the controller; under controller off status, pre and hold key for 3s can turn on the controller. Under the controller normal working status, screen display the current temperature value; also the controller can also switch the working mode between heating and cooling. Controller starts refrigerating with cool indicator light on when the measuring temperaturetemperature set value+ difference value, and the refrigerating relay is connected; the Cool indicator light flashes, it indicates the refrigerating equipment is under compreor delay protect status; when the measuring temperature temperature set value, the Cool indicator light on, and refrigerating relay disconnects. System starts heating when the measuring temperature value the temperature set value-difference value, and the Heat indicator light on, and the heat relay connects; when the measuring temperature temperature set value , the Heat indicator light is off, and the heat relay disconnects. Dual Display Temperature Controller Temperature control range: -55C~120C/-67F~ 248F Temperature control accuracy: 0.1 C / 0.1 F Display color: red + blue Working power supply: DC12V DC 24V AC110V~220V Sensor: NTC 10K 1 Meter (with probe) Product Size: 79.2mm41.9mm26.3mm Hole Size: 72.1mm39.2mm Operation and display panel Indicator light Operation guide 1. Short pre SET small digital tube to flash, pre or to set the target temperature, pre Standby button or no operation to save the setting within 3 seconds. 2. Pre and hold SET to enter the code setting mode, pre or to switch the code. After selecting, pre SET to enter the code setting. After setting, pre Standby button or no operation to save the setting within 3 seconds. . 3. The last parameter setting is saved by default after shutdown. 4, restore the factory settings: pre and hold "SET" to power on. 5. When the module is powered on, it will start directly. After power-on, pre and hold the standby button, the module will enter sleep or wake up; in case of power failure, the module will run automatically after power recovery, no need to start manually.
