W3230 12V 24V AC110-220V Probe Line 20A Digital Temperature Controller LED Display Thermostat With Heat/Cool Control Instrument

Feature:

100% new high quality. Cooling or heating mode of operation is available. Set the maximum/minimum upper limit temperature to avoid accidents. Automatically initiates cooling or heating at a constant temperature. Temperature calibration to calibrate the temperature as needed. When the temperature is high, the controller will alarm when the temperature reaches the set temperature. Product specifications:

Material: electronic components Colour: Black Temperature range: -55-120C Control temperature accuracy: 0.1° Display color: red and blue Power supply voltage: DC 12V / AC110-220V Data Save: Yes Relay: 20A Size: 79X43X26MM Package Include:

1 x Digital thermostat temperature alarm controller sensor

Instructions:

Connect the power supply and equment to supply power to the controller. At this time, it is displayed as measuring temperature. Pre SET once, the display temperature will flash, pre 11 to set the desired temperature (pre and hold + one to quickly raise and lower) After finishing, pre SET to confirm the return. At this time, the controller automatically performs relay on/off according to the setting! The output of the thermostat is 20A relay, which satisfies various high-power loads, and connects the control circuit to supply power to the thermostat. The display shows the ambient temperature. Indicator, digital tube and status descrtion Indicator light: Blinking indicates cooling or heating start delay, always on indicates that the relay is closed Digital tube: Display LL is the sensor open circuit, please connect the sensor according to the instructions; display HH is out of the measurement range, the thermostat will forcibly open the relay; display - for high temperature alarm Parameter function descrtion Pre and hold SET for 5 seconds to enter the main menu settings, pre + one to switch Po. .P6, long pre SET or 10 seconds without on action controller to automatically confirm the return. PO cooling and heating mode Pre and hold SET for 5 seconds to display PO, pre SET once to set the working mode, pre +- to switch [H is heating mode] [C is cooling mode] Pre SET once to return, long pre SET or 10 seconds without on action controller automatically confirm carry out. In the cooling mode: When the temperature measurement value > temperature set point, the refrigeration relay is closed and the refrigerator is started; when the temperature is measured, the quantity set value, the refrigerator will not start the cooling immediately, it needs to run after the set delay time. In the heating mode: the first power-on, if the current temperature < set value, the heater will not start heating immediately, it needs to run after the set delay time. The chiller starts immediately when the downtime between the two starts of the chiller or heater is greater than the set value of the delay start time. When the stop interval between the two starts of the refrigerator or heater is le than the set value of the delay start time, the device can start after restarting the set delay time of the set after the run. The delay time is calculated from the moment of shutdown. For example, the setting delay is 5 minutes in the cooling state, the cooling device starts to delay after the power is turned on, and the refrigerator is turned on after 5 minutes. When the required temperature is reached, the refrigerator stops, and the timing starts, when the next cooling start timing is completed. Work, the time is not completed before the end of the time to work, the LED indicator flashes during the delay. When the delay start is set to 0, it is equal to the off delay function. P8 factory reset Due to some human reasons, the internal setting of the thermostat is confusing. It takes a lot of time to set the item. In this case, you can use this function to restore the factory settings. The specific method is: in the off state, pre and hold the + and - ons at the same time, and then turn on the power, all the above parameters are restored to the factory settings.
