Intelligent temperature controller, Energy-saving and practicality
Microcomputer Temperature Controller
«User manual of MH1210A»
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;
Operation instruction:
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):
