YIERYI MH1210A User Manual

Microcomputer temperature controller

It suits most users in different environments for automatic intelligent control system of many kinds of

refrigeration, heating equipment. Refrigeration and heating mode could be set through the menu, the procedure

has been set the power outage permanent memory function.

Specifications:

1. working voltage: 12V DC or 220V AC

2. measurement range: -40 C~120 C; measurement error: ±0.5°C

3. control range: -40°C~120 C; temperature control precision: separation rate: 0.1°C; slewing range of

temperature: it could be adjusted in the range of 1 ~30°C

4. temperature sensor: NTC 25 C=10K B3435 ±1 % (1 miter length, no positive or negative)

5. output load: normally open 10A/AC220V

6. working environment: temperature: -20°C~70 C; humidity : 90%RH none moisture condensation ;

7. dimension of whole unite : 75(W)x34.5(H)x85(W) mm

8. trepanning dimension : 71(W) x 29(H) mm;

Press "set" button for 3s get into the procedure menu code mode, display the code "HC". Press "A" or "V" for

cyclical selection of parameter code of "HC-CP-LA-HA-PU-CA".

To enter a code, press the "Set" button, press the "A" button or the "V" button to change to the desired data and

press "Set" to save and exit;

Control the temperature set: press "Set" button, display blink and it is the default setting. Press "A " or "V " to

change the data and save automatically. (press on "A" or "V" for 2s or more to increase the adjusting speed )

heating control: when the temperature control mode ( code is HC) was H, e.g. the setting control temperature is

28 C , slewing range of temperature is 2 C , when the environment temperature >= setting temperature (28'C),

the relay will switch off and stop the output load; when the environment temperature <=setting temperature (28

C ) - slewing range of temperature (2 C ) and set "delayed start" before, the reply will switch on and output load

again, (if the delayed start function doesn't need, set the delayed start (code PU) to 0)

refrigeration control: when the temperature control mode (code is HC) was C, e.g. the setting control

temperature is 28'C, slewing range of temperature is 2 C, when the environment temperature <=after setting

"delayed start" time, the relay will switch on and sart output load.(suggest "delayed start" time to the default

setting time to protecting the compressor, please set the (code PU) to) if it doesn't need):

Page 2 Note: LA floor level and HA the up limit are not the temperature control parameter adjustment, change will reduce the temperature control range. Back to default setting: press the "Rst" button for 3s and display blink 5 times, all parameters back to default setting;...
Page 3 Note matters: 1. To prevent high-frequency interference, do not install the sensor line bundled with the power line and loaded equipment line, but should be separated wiring; 2. Supply voltage must be consistent with the rated voltage and the deviation is less than ± 10%. Strict distinction between sensor installation, power line and Loaded output interface;...
