KKnoon MH2000F Microcomputer Temperature Controller
Thank you for choosing Shenzhen’s “MEIHANG TECHNOLOGY” microcomputer temperature controller. This product gathers a wide range of modern heating and cooling technology, small size, lightweight, big range working voltage(AC90V~AC250V = 10% 50/60Hz), simple operation, accurate measurement and anti-interference ability, etc. It suits most users in different environments for automatic intelligent control systems of many kinds of refrigeration, and heating equipment. The procedure has been set for the power outage permanent memory function. specifications:
- Working voltage range: AC90V-250V ‡ 10% 50/60H2: Power consumption: 3W
- Power consumption of standing by ≤ 0.5W

Operation of buttons: status
Reset button, in the setting status; press this button one time to quit the
setting status, and back to the display
S: setting button, press S 3 seconds to get into the Menu code, it displays
Press S once more and again to cycle the parameter setting status parameter
code (refer to the attachment), if you want to adjust the parameter code
chosen, please press or when it appears and press save and quit.
up or down to adjust the parameter, press it for a long time it will adjust
quickly
Parameter setting
Heating mode: get into the parameter menu code model, after choosing the
code , press buttons or display “H” or “C”, after 3 seconds, it will save it
automatically, “H” means heating model, the setting control temperature is
40°F, slewing range of temperature is 2°F when the environment temperature ≥
setting temperature (40°F), the relay will switch off and stop the output
load; when the environment temperature ≤ setting temperature (40°F) – slewing
range of temperature (2°F) =38°F, the reply will switch on and output load
again:
Refrigeration control: get into the parameter menu code model, after
choosing the code Press buttons or it will display “H” or “C”, after 3
seconds, it will save it automatically, “C” means refrigeration, the setting
control temperature is 40°F, slewing range of temperature is 2F, when the
environment temperature 40°F, the relay will switch off and stop output load.
When the environment temperature ≥4 2F 40°F +2°F=42°F) the relay will switch
on and start the output load.
setting of temperature control: get into the parameter menu and choose to
press the button or change the parameter needed, it will save it automatically
after 3 seconds, (pressing button A or V for more than 2 seconds could adjust
the parameter quickly), this is the setting range of the temperature control
(range:-40~212°F)
delay start: get into the parameter menu and choose Press button or to
change the parameter needed, it will save it automatically after 3 seconds,
(pressing the button or for more than 2 seconds could adjust the parameter
quickly, this is the setting of delay start (range: 10minutes)
The setting of slewing range: get into the parameter menu and choose to
press the button or change the parameter needed, it will save it automatically
after 3 seconds, (pressing the button or for more than 2 seconds could adjust
the parameter quickly), this is the setting of delay start function (range:
0.1–50°F)
Code
Defective reminder
when the temperature sensor detects the up-limited environment temperature
of 212°F, it flashes H and turns off the output; when the temperature sensor
detects the down-limited environment temperature -40°F, it flashes L and turns
off the output too.
Note
- To prevent high-frequency interference, do not install the sensor line bundled with the power line and loaded equipment line, but should be separated the wiring
- Supply voltage must be consistent with the rated voltage and the deviation must be less than 10%. Strict distinction between sensor installation, power line and loaded output interface
- The temperature control host machine cannot be installed in a place where is dripping water, or the elderly, children could be touched
