The product adopts the latest electronic technique with LED display, which learn from the
advantages and experience of stand-alone edition temperature controllers domestically
and overseas. It is the most economical product with simple operation, stable performance,
small size and intelligent control, cool and heat shift functions, which applies to various
refrigeration and heating places and equipments.
Model:RC-112E
WORK indicator: means the output load is in working status; Normally on means work；
flash means delay；Off means not work.
SET indicator: means set status, Normally on means work; Off means not work.
1. Temperature setting：
In normal working status, press SET, display the current temperature value, use UP or DOWN
button to adjust the ideal temperature you want. Tips: press on UP or DOWN can enter into
rapid adjustment. After adjustment, press SET to return to normal working status, or without
any operation for 15 seconds, the controller will return to normal working status and save the
adjustments.
In normal working status, press on SET for 3 seconds, set indicator is on, and enter into
maintain menu. When display HC, use UP or DOWN button to adjust the mode you want. Tips:
press on UP or DOWN can enter into rapid adjustment. After adjustment, press SET to the
next parameter, use the same method to set the rest parameters. When finishing, press on
SET for 3 seconds or without any operation for 15 seconds, the controller will return to normal
working status and save the adjustments.
2. Maintain Parameters Setting:
When there is difference between the measuring temp. and the standard temp., this function
can keep the measuring temp. same as the standard temp.
Temp. after calibration =Temp. before calibration.+adjusted value

In heat mode:
A. Heating systems works in below situation:
The measuring temperature ≤ the set temperature - the temperature difference;
B. Heating systems stop working in below situation:
The measuring temperature ≥ the set temperature
3. Delay Time:
HS and LS can set the high and low limit of the setting temperature:
For example: HS is +15, LS is -10, the temperature only can be set between -10~+15℃;so if
you want to set a value beyond this range, please reset the HS and LS firstly.
4. High and low temperature limit:

In cool mode:
A. Cooling systems works in below situation:
The measuring temperature ≥ the set temperature + the temperature differential
B. Cooling systems stop working in below situation:
The measuring temperature ≤ the set temperature
2. Cool and Heat Function:
When power on for the first time, if The measuring temperature ≥ the set temperature + the
temperature differential or The measuring temperature ≤ the set temperature - the
temperature difference, the output will not be activated immediately, and will be activated after
the delay time.
When the controller is in power on status,if sensor open circuit, LED flash and display “
_ _”,if sensor short circuit, display “HH”. When in sensor error status, the output load will run as
the cycle: stop 15 minutes, then work 15 minutes.
When the sensor temperature＞99℃，display HH；When the sensor temperature＜-40℃，
display LL.

1.Before use, please carefully read the user manual, must distinguish the functions of the different
contact points. The connected load power should not exceed the capacity of contact point (if
exceeding, please connect AC contactor). Each connecting wire should be connected to the
terminals firmly.
2.Please install the device firmly in a stable place, avoid crash. The device cannot be placed with
dripping or water, and keep away from the electromagnetic interference of the electrical apparatus.
3.In order to prevent the interference of high frequency, the sensors and low voltage lines cannot
parallel and be bundled up with high voltage line. The diameter of the high voltage wire must be
between 0.75 mm and 1.5mm.
4.If the device is disturbed, please cut off the power, and restart. This software belongs to class A,
which is not applicable to safety protection control.
5.Do not privately disassemble the device. If faults occur or have questions of the usage, please
contact our company.
Installation notes:
If the time period between the previous stop and this starts is longer than the delay time, the
output will be activated immediately; if it is shorter than the delay time, the output will be
activated after the delay time. The delay time is calculated from the previous output stop.
