Menu code introduction
Menu code | Detail explanation | Explanation | Unit |
HC | Heating/Cooling | Working mode set | H=Heating,C=Cooling |
D | Return difference | Temperature difference between the Power-on and shutoff | ℃ |
LS | Set the lower limit | Min value of control temperature set | ℃ |
HS | Set the upper limit | Max value of temperature set | ℃ |
CA | Temperature correction |
| ℃ |
PT | Delay start | Min time interval of shutoff | ℃ |
AH | AL-H | AL-H | ℃ |
AL | AL-L | AL-L | ℃
|
Temperature controller set:Press"SET"one time,press three minutes to enter into setting menu after displayed flashing and displaying code HC then.
Heating mode:Set mode control mode(code HC) as H,it is heating mode
Such as set value of control heating as 35℃,temperature return difference is 2 °.When value of temperature ≤setting value(35℃)-difference return(2℃)relay start input at 33℃
Environment temperature≥setting temperature (35℃)relay start output
Cooling mode:set mode control way(code HC) as C,it is cooling mode.
For example,set cooling temperature as 35℃,return difference is 2°.When value of temperature ≥setting temperature value (35℃)+return difference(2℃)37℃ relay will start output
When environment temperature value ≤setting humidity value(35℃) relay will close output
HC:Mode selection,C means cooling mode,H means heating mode
D:Return difference,when temperature starting in heating mode=displaying temperature-return difference.when temperature starting in cooling mode=displaying temperature+ return difference
D:return difference ,when temperature starting in heating mode=displaying temperature-return difference,when temperature starting in cooling mode=displaying temperature+return difference
PU:Delay start,when relay start timing at relay stop output,the next starting time interval must greater than delay start time to avoid frequent startup.
HS:Temperature upper limit alarm;when temperature exceed high alarm setting,digital tube showing "HHH",when temperature lower than alarm setting value,it will exist automatically.
LS:Temperature lower limit alarm:when temperature exceed low alarm setting,digital tube showing "LLL"temperature higher than alarm setting value ,it will exist automatically
CA temperature correction:temperature correction value add into humidity value,for example:temperature displaying 35℃ calibration temperature increase 5℃,displaying temperature should be 40℃
Restoration:Press up and down keyboard on the left,screen displaying 888,it will restore factory setting
PT:Delay to start ,For example:delay time for 1 minutes,when temperature reached at setting value,relay will start up after delay on 1 minutes.
AH:High temperature alarm:For example:Set ultra high temperature alarm temperature at 50°,buzzer alarming when temperature higher than 50°
AL:Low-temperature warning:For example:set low temperature alarm temperature at 20℃,buzzer alarming when temperature lower than 20°

Set the time:Press the "SET"keyboard two time,then press three seconds after digital tube shows flashing and enter into set menu,it is displaying code"PO".
Time control:set the way of mode control PO as (ON) open type control mode.
P1:Group 1 time power-on set.For example,set up time at 8:00,temperature controller start working when time is equal or greater than 8:00
P2:Group 2 time shutdown set.For example,set up time at 10:00,temperature controller stop working when time is equal or greater than 10:00
P3:Group 3 time power-on set.For example,set up time at at 11:00,temperature controller start working when time is equal or greater than 11:00
P4:Group 4 time shutdown set.For example,set up time at 13:00,temperature controller stop working when time is equal or greater than 13:00.
P5:Group 5 time power-on set.For example,set up time at 18:00,temperature controller starts
working when time is equal or greater than 18:00.
P6:Group 3 time shutdown set.For example,set up time at 20:00,temperature controller start working when time is equal or greater than 20:00
P7:Time end alarm,for example,set the work time at 8:00 to 10:00,buzzer start alarming when time exceed 10:00
