Method of use

When the power supply and equipment are connected, power supply can be provided to the controller. At this time, the display is displayed as the measured temperature. Press the SET key once, and the display temperature flashes. The thermostat output for 20A relay, to meet a variety of high power load, connected to the control circuit, can supply power for the thermostat, at this time the display display for the environment temperature.

Indication of status of indicator light, nixie tube and buzzer

Indicator light: flashing indicates refrigeration or heating start delay, constant light indicates relay has been closed

Digital tube: display LL opens the way for the sensor, please connect the sensor according to the instructions; HH shows that outside the measuring range the thermostat will force the relay to disconnect; Display -- -- alarm for high temperature

Parameter function description

Long press SET for 5 seconds to enter the main menu setting, press +- to switch P0... P6, long press SET or 10 seconds no button action controller automatically confirm return.

P0 cooling and heating mode

Long press SET for 5 seconds to display P0, press SET once to SET the working mode, press +- to switch [H for heating mode] [C for cooling mode] and press SET once to return, long press SET or 10 seconds for no button action controller to automatically confirm completion.

In the refrigeration mode: when the temperature measurement value the temperature setting point, the refrigeration relay absorbs and the refrigerator starts; When the temperature measurement value is less than or equal to the temperature setting point - return difference, the refrigeration relay is disconnected and the refrigerator is closed.

In the heating mode: when the temperature measurement value is less than or equal to the temperature setting point, the heating relay will suck in and the heater will start. When the temperature measurement value temperature setting point + return difference, the heating relay is disconnected and the heater is closed.

P1 error setting

Long press SET for 5 seconds to display P0, press +- to switch to P1, press SET once to SET back difference value, press +- to SET back difference value to 0.1-15, press SET once to return after completion, long press SET or 10 seconds no button action controller automatically confirm completion.

In the refrigeration mode: when the temperature measurement value set value, the relay suction, the refrigerator start; When the temperature measurement value is less than or equal to the set value -- the return difference value, the relay is disconnected and the refrigerator 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 ℃.

Heating mode: when the temperature measured value set value, the relay suction, heater start; When the temperature measurement value set value + return difference value, 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 ℃.

P2 set upper limit for maximum temperature

In order to avoid the risk of setting the temperature too high due to the wrong operation of others, this thermostat has the highest setting upper limit function, which limits the setting range of the maximum temperature setting point controlled by the thermostat.

Long press SET for 5 seconds to display P0, press +- to switch to P2, press SET once to SET the maximum limit, press +- to SET the maximum temperature, the maximum value is 110, press SET once to return after completion, long press SET or 10 seconds no button action controller 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.

P3 set the lower limit at the lowest temperature

In order to avoid the ice blocking caused by the wrong operation of others, this thermostat has the function of setting the minimum upper and lower limit, which limits the setting range of the minimum temperature setting point controlled by the thermostat.

Long press SET for 5 seconds to display P0, press +- to switch to P3, press SET once to SET the minimum lower limit, press +- to SET the minimum settable temperature, the minimum value is -50, press SET once to return after completion, long press SET or 10 seconds no button action controller automatically confirm completion.

For example, is set to the temperature set point set to a minimum of 2 ℃ to lower the temperature set point temperature scope, need to adjust the lower limit value.

factory data reset

Due to some man-made reasons, the internal Settings of the thermostat are confused. It takes a lot of time to set them one by one. At this time, this function can be used to restore the factory Settings.
