IIProgrammable touch screen controller

1. Adopting a LCD display type screen button programmable temperature and humidity controller, a large viewing angle high contrast LCD display with backlight function

2. Fixed conditions or program conditions can be set arbitrarily

3. Fixed conditions can be set for a time of 0-99H59min

4. The programmable mode can simultaneously set up 10 sets of programs with different conditions. In any set of programs, a partial number of segments can be intercepted to execute the loop

5. Within each program group, up to 100 different temperature, humidity, and time segments can be set (up to 99 hours and 59 minutes per segment), and 10 programs can be connected in series. The maximum number of cycles for each segment can reach 550 times

6. Equipped with a power-off memory device, the remaining programs can continue to be executed when the power is restored

7. The temperature rise and fall can be controlled by slope and has the function of self correcting temperature and humidity reference points

8. It has TIMER SIGNAL OUTPUT RELAY, which can output the control contacts required by another control program to the outside during any stage of the process

9. The temperature sensor adopts DIN PT-100 Ω

10. Both temperature and humidity control adopt the BTHC system; Control S.S.R. in a P.I.D. manner; Make the heating and humidification capacity of the system equal to the loss of heat and humidity, so that it can be used stably for a long time, and improve the stability and lifespan of control components and interfaces

11. It has the function of P.I.D. automatic calculation, which can reduce the inconvenience caused by manual setting

When an error occurs during setup or operation, a signal will be provided

13. Power outage memory device for five years

14. The controller has a recording signal output and a picture lock (LOCK) function

3、 Freezing system

1. European and American energy-saving fully enclosed industrial low-temperature compressor

2. The cooling method adopts air-cooled, and the entire series uses environmentally friendly refrigerants

3. Dry filters, solenoid valves, and other refrigeration equipment

4. The condenser is air-cooled and equipped with a cooling motor device or water-cooled coil

5. The low-temperature system adopts a binary refrigeration circuit, which has a fast cooling speed

6. Expansion system: a capillary capacity controlled refrigeration system
