Operation
Set Set-Point
Press〖S〗to enter into the set status. The current set-point value displays.
Press〖▲〗or〖▼〗 to set the value (keeping depressed can fast set).
The status will exit, and the setting will be saved, if no key operation within 6 seconds.
Factory default set is 100℃. Range is from LS to HS (see parameter code table below).
Set System Parameters
Keep〖P〗depressed for 6 seconds to enter into parameter setting status.
Press〖P〗to select the parameter code (see parameter code table below). Press〖▲〗or〖▼〗to set the value.
The status will exit, and the settings will be saved, if no key operation for 6 seconds.
Parameter Code Table
Code Function Range Factory Default Set
LS Low temperature warning 0 ~ (set-point – hysteresis - 1) 0℃
HS High temperature warning (set-point + hysteresis) ~ 415℃ 415℃
Pt Delay protection 0 ~ 3 minute 0 minute
CA Calibration -15 ~ +15℃ 0℃
d Hysteresis 1 ~ 15 ℃ 5℃

Control
Heating Control
If Troom ≤ Set-point -【 【d】 】, and R1 has been de-energized for 【 【Pt】 】, then R1 energized;
If Troom ≥ Set-point +【 【d】 】, then R1 de-energized.
R1 Load Delay Protection
After power supplied, R1 could be energized after 【 【Pt】 】;
After R1 de-energized, it could be energized again after 【 【Pt】 】.
Warning
 When sensor fails, Blinking display the failure code “LL” or “HH”, buzzing, R1 de-energized.
 If Troom ≥【HS】, blinking display “EH”, buzzing, warning output (R2 R3) acts (see table below), R1 de-energized.
 After power supplied, and after once having reached to set-point +
【

,
, i if f Troom ≤【LS】, blinking display “EL”, buzzing, warning
output (R2 R3) acts (see table below), R1 energized.
Note: when buzzing warning, pressing〖P〗will stop buzzing.
Warning Output (R1 R2) Table:
Terminal Remark
R3 After power supplied: open when warning, closed when no warning. When no power supply: open
R2 After power supplied: closed when warning, open when no warning. When no power supply: closed
COM Common terminal
Calibration
The sensor absolute accuracy could be calibrated by setting【 【CA】 】.
Restore to Factory Default Settings
Under none-setting status, keep all four keys depressed simultaneously for 6 seconds, the “8888” will display, and all system
parameters will be restored to factory default settings.
Installation
1st: Insert into drilling hole;
2nd: Clamp
Attention
 Do not make wiring (R1, R2, R3 and sensor) when power supplied.
 Wiring work should be manipulated by certified technicians.
 Wrong connection could damage the controller, and the loads. Power supply to terminal 7 and 8 to check the controller. If there is a
multimeter, check the outputs, as well as input, by the help of settings.
 Sensor and input signal wires should not be laid together with power supply wire, and even in same pipe.
 Sensor wire is better as short as possible. Not wind the redundant length wire to electrical noise equipment.
 The loads should be within the specification of the controller output driving ability. If using ac/dc module as load, or tungsten lamp,
or motor, following the below requirements to avoid surging current damaging or shorten the life time of the controller outputs:
For ac/dc module as load, the rated current should be no more 1/10th of output specification under pure resistance.
For tungsten lamp as load, the rated current should be no more 1/15th of output specification under pure resistance.
For motor, the rate current should be no more 1/5th of output specification under pure resistance.
For example: a 3A (pure resistance spec.) relay, if drive a 660W tungsten lamp with, the relay contactor will be burnt
immediately, if drive a 0.2A tungsten lamp (44W), the life-time will be guaranteed.
 Don’t touch inside components;
 Avoid installing controller in the following
environment:
More wet than 90%RH, or easily dew; Vibrating, or
will be shocked; Possible sprayed; Under erosive
air; Under explosive air.
