3. Application method
When the power supply and equipment are connected, power can be supplied to the controller. At this time, it is displayed as measuring temperature. Press SET key once, and the display temperature flashes.The output of the thermostat is 20A relay, which meets various high-power loads. When the control circuit is connected, power can be supplied to the thermostat. At this time, the display shows the ambient temperature.
Indicator light, digital tube and buzzer status description
Indicator light: flicker indicates start delay of refrigeration or heating, and constant light means the relay is closed
Digital tube: display LL opens the way for the sensor, please connect the sensor according to the instructions;It is shown that HH is beyond the measuring range and the thermostat will forcibly disconnect the relay.Display -- -- alarm for high temperature

4. parameter function description
Long press SET 5 seconds to enter the main menu setting, press +- switch P0...P6, long press SET or 10-second keyless action controller to automatically confirm return

P0 refrigeration and heating mode:
Long press SET 5 seconds to display P0, press SET to SET operating mode, press +- switch [H is heating mode] [C is cooling mode] to press SET to return, long press SET or 10 seconds to confirm automatically.
In the refrigeration mode: when the temperature measurement value is greater than or equal to the temperature setting point, the refrigeration relay is sucked up and the refrigerator is started;When the temperature measurement value is less than or equal to the temperature set point - return difference, the refrigeration relay is disconnected and the refrigerator is closed.
In the heating mode: when the temperature measurement value is no more than or equal to the temperature setting point, the heating relay is sucked up and the heater is started;When the temperature measurement value is greater than or equal to the temperature setting point + the return difference, the heating relay is disconnected and the heater is closed.

P1 reset setting:
Long press SET 5 seconds to display P0, press +- to switch to P1, press SET to SET the return difference once, press +- to SET the return difference to 0.1-15, press SET to return once after completion, long press SET or 10 seconds without button action controller to confirm the completion automatically.

In the refrigeration mode: when the temperature measurement is greater than or equal to the set value, the relay is closed and the refrigerator is started;When the temperature measurement value is not equal to the set value - return difference value, the relay is disconnected and the cooler is closed.
Environment is 30 ℃ set data is 25 ℃, for example, set the return difference as 2 ℃, the electric relay closed refrigerating unit after the start, when the refrigeration to 23 ℃, relay disconnect refrigerating unit shut down, at this time due to the refrigerating unit has been disconnected temperatures began to rebound, when back up to the value of 25 ℃, relay closed refrigerating unit to start again, so repeated cycle control temperature is not higher than 25 ℃.
In the heating mode: when the temperature measurement value is not equal to the set value, the relay is closed and the heater is started;When the temperature measurement is greater than or equal to the set value + the return difference, the relay is disconnected and the heater is closed.
Environment for 10 ℃ set data is 25 ℃, for example, set the return difference as 2 ℃, the electric relay closed after the heater starts, when heated to 27 ℃, relay disconnect heater closed, at this time due to the heater has disconnect temperature starts to drop, to the present value of 25 ℃, the relay closed heater to start again, so repeated cycle control temperature is not lower than 25 ℃.

Maximum setting limit of P2:
In order to avoid the danger of setting the temperature too high due to the misoperation of others, this thermostat has the function of setting the upper limit and limiting the setting range of the highest temperature setting point controlled by the thermostat.
Long press SET 5 seconds to display P0, press +- to switch to P2, press SET once to SET the maximum upper limit, press +- to SET the maximum temperature that can be SET, the maximum value is 110, press SET to return after completion, long press SET or 10 seconds to automatically confirm completion.
Set to 60, for example, the highest temperature set point can only be set up to 60 ℃ to higher temperature set point temperature scope, need to adjust the upper limit value.

Restore factory Settings:
Due to some artificial reason, the internal setting of the thermostat is chaotic, and it takes a lot of time to set one by one. At this time, the factory setting can be restored with this function. The specific method is: in the state of shutdown, press + and - button at the same time, and turn on the machine.
