-The red digital tube displays the actual temperature sensed by the sensor between 9 ℃ and 99 ℃. The left and right green digital tubes respectively display the user set stop temperature and start temperature. Due to the two requirements of heating control and cooling control, this controller also has two operating modes: "high temperature start" and "low temperature start".

1. High temperature start (cooling control): When the "start temperature" is greater than the "stop temperature", the thermostat is in the "high temperature start" state. For example, as shown in the left figure, the measured temperature is 26 ℃, the "stop temperature" is set to 20 ℃, and the "start stability" is set to 30 ℃. At this time, the machine is turned on, the running indicator light (green light) is on, and the socket is powered on. When the measured temperature is below 20 ℃, the machine will shut down. The standby indicator light (red light) is on, and the socket is powered off at this time. This starting method is mainly used for cooling, such as turning on air conditioning, exhaust fans, etc.

2. Low temperature start (heating control): When the start temperature is lower than the stop temperature. The thermostat is in the "low temperature start" state. For example, set the "stop temperature" to 30 ℃. If the starting temperature is 20 ℃, then when the measured temperature is less than or equal to 20 ℃. The machine is turned on and the running indicator light (green light) is on. At this time, the socket is supplying power.

When the measured temperature is greater than or equal to 30 ℃, the machine shuts down, the standby indicator light (red light) lights up, and the socket is powered off. This start-up method is mainly used for heating.

3. Alarm function: When the temperature sensor malfunctions or detects a temperature value<-9 ℃ or>99 ℃, the buzzer will sound an alarm and the digital display will show "Er." cutting off the power supply to the socket. Troubleshooting restores normal operation- 9 ℃ or above

Multipurpose: Suitable for temperature control in places such as boilers, water pumps, water heaters, electric heating equipment, geothermal water heating, geothermal film, underfloor heating, heating cables, electric kang, electric painting, hot and cold ventilation fans, insulation boxes, breeding farms, breeding rooms, bacterial fermentation, seed germination, etc.

Press the SET button to switch between the four modes of temperature control, F1, F2, and F3.

1. F1 "is an intermittent time control mode. The middle digital tube displays "F1" (similar to the refrigerator's voice recognition function). The left side of F1 corresponds to the stop time: set by pressing the up and down keys (1-99 minutes). The right side of F1 corresponds to the opening time: press the up and down keys (1-99 minutes) to set. As shown in the left figure, set "05" on the left side of F1 and "10" on the right side, that is, stop for 5 minutes and start for 10 minutes. The red indicator light is on when the machine is stopped. The green indicator light is on when turned on. Such a cycle.

2. F2 countdown time control mode. The setting range is between 0001 and 9999 minutes. Left corresponding time: set from 0 to 99. The corresponding time on the right is set from 0 to 99. The left side corresponds to the thousand and hundred digits of the timed time. The right side corresponds to the ten digits of the timed time. As shown in the left figureIf the left digital tube is set to "12" and the right digital tube is set to "00", the timer time will be 1200 minutes, which is 20 hours. When the set time is reached, the socket will power off and the green light will turn off. The red light is on. Apply timed shutdown, such as timed charging of electric vehicles, etc.

3. F3 "reservation time control mode. The setting range is between 0001 and 9999 minutes. Left corresponding time: set from 0 to 99. The corresponding time on the right is set from 0 to 99. The left side corresponds to the thousand and hundred digits of the timed time. The right side corresponds to the ten digits of the timed time. As shown in the left figureSet the appointment for 20 minutes, after which the green indicator light will turn on and the socket will be powered on. Scope of application, scheduled start-up.
