A variety of modes can be switched， if you are used only for temperature control function， choose P-4， P-5 or P-8mode;

P-1: The relay (can be set separately pull and release times and cycle times)

P-2: Voltage relay (voltage can be set upper and lower limits)

P-3: Voltage control relay

P-4: Temperature relay (can be set upper and lower temperature and the heating or cooling mode)

P-5: Temperature time relay

P-6: Temperature voltage relay

P-7: Temperature voltage time relay

P-8: Temperature alarm mode (the temperature exceeds the set upper and lower limits relay)

P-1 time relay mode

Make use of the timing relay or time relay， time range: 0-999 seconds or 0-999 minutes， switch;

Cycle execution:

By the time the relay mode， the user can set the relay pull-time T1 and release time T2， T1 is set to three seconds for example， T2 is seven seconds， then the relay run will first perform three seconds then pull time of 7 seconds release， and so on.

When you set the T1 and T2 times， the system will be powered down to save the set value， the next time you run P-2 mode automatically be loaded T1 time to wait to start running.

After pressing the SET to set time values T1 and T2 state， press the SET button to set the execution cycle times， maximum 999 times. The number is set to 0 infinite loop execution. When the timer is running， press the SET button for three seconds byTiming values are shownSwitch toCount the number of cyclesDisplay.

Single execution timing:

If only set T1 (pull time)， T2 (release time) is 0， the relay timed run after T1 time to stop， no cycle operation， this time can be used as a timer， T1 time time to complete， the relay is released， At this point press the ENTER key， the system will re-start the timer to T1 time.

If T1 (pull time) is set to 0， the relay has been in a released state (not up and running， turned normally closed， normally open disconnected).

P-2 voltage relay moduleFormula

Under voltage relay mode and temperature control relay mode， the user can set the upper limit control value， when the detected voltage or temperature exceeds the upper limit of the relay by a pull into a release until the voltage is below the lower limit set just pull again relay， this function can be used for voltage monitoring， temperature control， etc.， can also be used as a DC voltmeter and thermometer， voltmeter display range: default shipping is 0-99.9V， error 0.1V. Temperature display range -55.0-99.9 Error 0.5 .

Required voltage detection range of 0-9.99VHardware version error 0.01V Please Remarks.

Press SET button for three seconds after the release， relay status negated， namely the detection voltage or temperature exceeds the upper limit of the relay， the detection voltage is lower than the lower limit of the relay releases.

P-3 voltage relay mode:Is "P-1" mode and "P-2" combined mode， the user can control the timer start by detecting the voltage value.For example: When the voltage exceeds the upper limit start timing of 10 minutes after disconnecting.

P-4Thermostat relay mode

Mode Select "P-4"， this time into the Thermostat relay mode， the user can set the temperature exceeds the upper limit of the relay， below the lower limit of the release， or is set to exceed the upper limit of the release， below the lower limit pull.

Temperature sensor DS18B20 real-time acquisition and ambient temperature through a digital display， temperature range:-55.0~99.9， display precision 0.1 ， error 0.5 ， the minimum temperature ofSetting mode is identical with the voltage relayWhen the temperature is below zero value， digital control point on the last digit indicates the temperature is below zero.

You can set the temperature control of the upper and lower back as the temperature difference is too large to avoid temperature fluctuations cause the relay to frequent movement.

To set upper and lower limits of minus value， short pressSETKey to enter the upper and lower limits setting， pressSETAfter three seconds， release to the upper or lower switching temperature value minus the value of a digital control point on the far right shows the temperature of minus value， pay attention to the actual value minus the value of the upper temperature limit is lower than the lower limit of the actual value， for example， set up fixed upper limit22.5 lower limit is20.5， then switch to the upper limit of minus-22.5， the lower limit is-20.5， then the detected temperature is lower than-22.5 deemed to exceed the upper limit.

You can setHeating or cooling modeIf you needTemperature exceeds the upper limitStarter relay， orTemperature is below the lower limitStart relay， can be switched by pressing the SET button for three seconds and release action.
