    The module runs on a 12V DC supply and draws about 20mA or 70mA when the relay is energised. Here's the programming info: A brief press of SET enters the main temperature adjustment mode with the current set temperature flashing. This can be adjusted with the UP/DN buttons, and holding them will make them auto-repeat. When finished adjusting, the unit will store your new setting and revert back to normal operation after several seconds. Holding down SET for about 5 seconds will enter programming mode. You can step through the program parameters from P0 to P6 with the UP/DN buttons and use SET to select them. P0 Selects cooling mode or heating mode.In cooling mode (C) the relay will energise and close the contacts when the probe temperature is above the set temperature.In heating mode (H) the relay will energise and close the contacts when the probe temperature is below the set temperature. P1 Allows you to set a hysteresis value between 0.1 to 15 degrees.The hysteresis value is to prevent the relay chattering ON and OFF when the probe is wavering around the set temperature point.For instance, with hysteresis set to the default of 2 degrees, when in cooling mode and the temperature is set to 25 degrees, the relay will activate as soon as that temperature is reached, but not deactivate until the temperature is brought down to 23 degrees (25 degrees minus a hysteresis value of 2 degrees)When in heating mode the relay would activate as soon as the temperature fell to 25 degrees, but would remain on until it reached 27 degrees. (25 degrees plus a hysteresis value of 2 degrees.) P2 Highest temperature limit. Set to 110 degrees by default. This is used to limit the upper temperature than can be set. P3 Lowest temperature limit. Set to -50 degrees by default. This sets the lowest temperature than can be set. P4 Probe correction. Very neat. Allows you to calibrate the temperature the probe is sensing by +7.0 to -7.0 in tenth of a degree increments. P5 Relay energisation delay of between 0 to 10 minutes to limit fast cycling of equipment like compressors. After setting this function the unit must be powered off and on again for the change to take effect. When I tested this it switched after about 35 seconds with a delay of "1" and about 1:40 with a delay of "2". P6. This is an over-temperature limit that turns off the relay and displays a row of dashes on the display.

    This is an excellent little thermostat with all the necessary adjustment and programming options. Instructions are only in Chinese and may be difficult to figure out all the options available. To set setpoint just press Set and use the + and – buttons. Press Set again when the value is at your choice. If you press Set for 2 or 3 seconds you enter the options and P0 will show. Use + and - to travel to P0 to P6 options. Press Set to adjust one off then when it is displaying. Use + and - to travel to options/values for the option. Set again when finished. Options are as follow: P0 - Chose cooling (C) or heating (H); P1 – Set hysteresis between 0,1 and 15 ºC; P2 – Set hi scale value (110ºC by default); P3 – Set low scale value (-50ºC by default); P4 – Correct measured temperature (for adjusting some error) P5 – Delay start time from 0 to 10 minutes; P6 – Set hi temperature alarm between 0-100ºC (by default it is off). Contacts K0 and K1 are normally open contacts of the relay and are independent off the 12V alimentation of the thermostat so they can control a 110V circuit.

    Première photo la température ambiante. Deuxième photo Appui court sur set pour entrer la température de consi!gne 23.2 . Troisième photo appuie long puis + pour sélectionner P1 qui est l hysteresis. Appui sur set pour entrer l hysteresis ici 0,5 (2 degrés la valeur par défaut) attendre 5seconde pour le retour à l affichage. Mettre son doigt sur la sonde pour monter en température a 23.7 (23,2 + 0,5 hysteresis) la led s allume et le relai colle. On retire le doigt de la sonde la température baisse. La led s éteindra à la température de consigne 23,2

    Well buildt, and solid quality. Here are the instructions which were missing with my units: Setting the trigger temperature: To set the trigger temperature press the button marked 'SET'. The seven segment display will flash. You can now set a trigger temperature (in oC) using the '+' and '-' buttons in 0.1 degree increments. If no buttons are pressed for approximately 2 seconds the trigger temperature will be stored and the display will return back to the current temperature. Setting the parameters P0 to P6: To set any parameter first long press the 'SET' button for at least 5 seconds. The seven segment display should now display 'P0'. This represents parameter P0. Pressing the '+' or '-' buttons will cycle though the various parameters (P0 to P6). Setting the cooling or heating parameter P0: The parameter P0 has two settings, C and H. When set to C (default) the relay will energise when the temperature is reached. Use this setting if connecting to an air-conditioning system. When set to H the relay will de-energise when the temperature is reached. Use this setting if controlling a heating device. Setting the hysteresis parameter P1: This sets how much change in temperature must occur before the relay will change state. For example if set to the default 0,2 oC and the the trigger temperature has been set to 25.0 oC, it will not de-energise until the temperature falls back below below 24.8 oC. Setting this hysteresis helps stop the thermostat from continually triggering when the temperature drifts around the trip temperature. Setting the upper limit of the thermostat parameter P2: This parameter limits the maximum trigger temperature that can be set. It can be used as a safety to stop an excessively high trigger temperature from accidentally being set by the user. Setting the lower limit of the thermostat parameter P3: This parameter limits the minimum trigger temperature that can be set. It can be used as a safety to stop an excessively low trigger temperature from accidentally being set by the user. Setting temperature offset correction parameter P4: Should you find there is a difference between the displayed temperature and the actual temperature (for instance if the temperature probe is on a long run of cable) you can make minor corrections to the temperature reading with this parameter. Setting the trigger delay parameter P5: This parameter allows for delaying switching of the relay when the trigger temperature has be reached. The parameter can be set in one minute increments up to a maximum of 10 minutes. Setting the high temperature alarm parameter P6: Choose on or off, if on is chosen, push set again to set alarm temperature. Setting a value for this parameter will cause the relay to switch off when the the temperature reaches this setting. The seven segment display will also show '---' to indicate an alarm condition. The relay will not re-energise until the temperature falls below this value. The default setting is OFF. Have fun!

    Works like a charme. Hold set button for 5 to 6 seconds to enter programable mode. P0 Mode set(Heating or Cooling) C/H P1 Set return difference 0.1-15 P2 Up limit 110 110 P3 Down limit -50 -50 P4 Temp. Adjust -0.7-7℃ 0 P5 Delay start time 0-10 minutes P6 High temp.alarm 0-110℃ At “OFF” state, Long press + -,start and then recovery to inital set When in program mode Press +/- to scip P1 to 6 / press set to sellect P* / press +/- to set P* / press set to hold p* / press +/- to skip to other P*.. Do 5 seconds nothing returns to temp probing. Press set to set desired temp with +/-

    Nice little thermostat. Working as promised. Temperature measurement is accurate. It is not so easy to setup without any user manual.

    L'unica cosa negativa e' il tempo di attesa per riceverlo per il resto tutto ok .Termostato molto versatile e settabile per varie funzioni . Allego foto per programmazione in quanto quella che ho trovato nella confezione e' in cinese. Una contenitore dedicato magari trasparente sarebbe stato gradito .

    It does what it says it does. And it is quite accurate - I took my own temperature and it showed 35.6 degrees Celcius, which means it shows one degree less (but this can be easily compensated). Detailed instructions can be found here http://www.kelco.rs/katalog/images/17670.pdf. As the instructions suggest, I would not use the relay for something more than 5 Amps at 220 VAC, but you can control with it an industrial relay which means that you can practically switch ON - OFF really huge currents. Really useful, easily programmable, with reversible function (Hot or Cold), with adjustable hysteresis, with error compensation, with LED display and a rock bottom price. Thank you Banggood.

    I bought 3 kits. Great thermostat at a small price. For usage documentation: www.kelco.rs/katalog/images/17670.pdf Test parameters: P0 = C (default), P1 = 0.8 ° C (hysteresis), limit temperature = 33 ° C. Photo 2: error - probe not connected. Photo 3: led ON - closed relay contact - temperature below set maximum limit. Photo 4: led OFF - open relay contact - lower temperature than set hysteresis limit.
